300-835
Automating Cisco Collaboration Solutions (CLAUTO)
300-835 CLAUTO Exam Guide: Scope, Blueprint, Preparation, and Scheduling Decisions
Cisco 300-835, CLAUTO, was designed to validate the programming, API, automation, and Python knowledge used to automate and extend Cisco Collaboration platforms. It served candidates pursuing the collaboration automation concentration associated with CCNP Collaboration and Cisco Certified DevNet Professional, as well as the Cisco Certified DevNet Specialist—Collaboration Automation and Programmability certification. The key decision now is not simply how to study: Cisco announced a last test date of February 2, 2026, so candidates must first confirm whether the exam is still available before investing in a preparation plan.
What did 300-835 validate?
300-835 focused on applying automation and programming techniques to Cisco Collaboration products rather than testing collaboration administration in isolation. Cisco’s v1.2 description identifies programming concepts, APIs, automation protocols, and Python programming as central areas of knowledge.
The exam was intended for professionals who needed to build or maintain integrations around collaboration platforms. That includes engineers working with Cisco UCM, contact-center tooling, collaboration endpoints, Webex services, and applications that extend those systems through code or APIs.
This is a different preparation profile from a purely operational collaboration exam. A candidate could understand call flows and platform configuration yet still need practice with authentication, request and response handling, data formats, API behavior, Python structure, and troubleshooting automation failures.
Cisco associated 300-835 with both the CCNP Collaboration and Cisco Certified DevNet Professional certification paths. Cisco’s CLAUI course documentation also states that passing the exam earned the Cisco Certified DevNet Specialist—Collaboration Automation and Programmability certification and fulfilled the concentration-exam requirement for those certification paths. Verify the current certification rules before relying on historical pathway information.
Should you schedule 300-835 now?
Check Cisco’s current exam-status and certification pages before scheduling. Cisco announced that 300-835 CLAUTO was scheduled to sunset, with February 2, 2026 as the last day to test on the v1.2 topics and February 3, 2026 as the first day for the updated certification changes.
Cisco’s retired-exams policy says retired exams are no longer available for certifying or recertifying. Therefore, a candidate who has not already confirmed an available appointment should treat 300-835 as a legacy exam and verify the official status rather than assume that a booking page or old study material represents a current option.
If you were pursuing 300-835 before the announced deadline, compare your intended appointment date with the last day to test, then confirm the exam name and version with Cisco’s official registration route. Do not rely on a third-party calendar, an old course listing, or an undated practice product.
If the exam is no longer available, the sensible next action is to review Cisco’s current collaboration certification portfolio and exam blueprints for a replacement path. The 300-835 v1.2 blueprint remains useful as historical evidence of automation skills, but it should not be treated as a current promise of eligibility, delivery, or certification credit.
Which skills carried the most blueprint weight?
The v1.2 blueprint places the greatest emphasis on Unified Communication and Cloud Collaboration, each weighted at 25%, while Collaboration Endpoints is weighted at 20% and Network Programmability Foundation is weighted at 10%. Use the domain labels with the percentages when prioritizing study; the percentages are not interchangeable measures of difficulty.
Unified Communication is weighted at 25% and includes Cisco UCM AXL SOAP API automation, CTI APIs, the Serviceability Perfmon API, CDR, IP Phone Services, and Finesse REST APIs and Gadgets. This domain calls for platform-specific API knowledge alongside general integration discipline.
Cloud Collaboration is weighted at 25% and covers Webex REST APIs, administrative operations, Python automation of Webex spaces and memberships, bots, embedded and service apps, Webex Widgets, and Webex SDKs. Candidates should connect each API topic to a practical workflow instead of learning product names as disconnected vocabulary.
Collaboration Endpoints is weighted at 20% and appears as a distinct domain in Cisco’s v1.2 blueprint. Because the supplied research identifies the domain but does not provide a full item-by-item breakdown here, use the official blueprint as the authority for its detailed objectives rather than inferring coverage from unrelated endpoint documentation.
Network Programmability Foundation is weighted at 10% and covers Git operations, REST, RPC, and SOAP API styles, synchronous and asynchronous API consumption, Python fundamentals, virtual environments, and deployment components such as load balancers, firewalls, DNS, and reverse proxies.
A practical allocation decision follows from the blueprint: build a working foundation first, then spend the largest blocks of hands-on time on the two 25% domains, reserve deliberate endpoint practice for the 20% domain, and revisit foundation topics whenever they block work in the product-specific domains. This is a study recommendation, not a Cisco scoring rule.
What should you know in the programming foundation?
Start with the Network Programmability Foundation because weak fundamentals can make every later API exercise look like a product problem. The v1.2 domain includes Git, API styles, synchronous and asynchronous consumption, Python fundamentals, virtual environments, and common deployment components.
Your first study pass should distinguish REST, RPC, and SOAP by how they expose operations, represent requests, and return responses. Then practice reading API documentation: identify the endpoint or operation, required parameters, authentication method, response format, error behavior, and any pagination or state considerations documented by the service.
For Python, prioritize code comprehension and small automation tasks. Be able to follow variables, functions, loops, conditionals, collections, imports, exception handling, and structured data processing. Create a virtual environment, install only the dependencies needed for a small script, and record how the environment is reproduced.
Use Git as a working habit rather than a list of commands. Create a repository for study scripts, commit a functioning baseline, make a focused change, inspect the diff, and recover from a deliberately incorrect edit. This gives each API exercise a traceable starting point and makes debugging more disciplined.
Do not neglect deployment vocabulary. A script may work locally yet fail when DNS, a reverse proxy, firewall rules, or a load balancer changes how traffic reaches it. Draw a simple request path and identify which component resolves names, filters traffic, distributes requests, or forwards them to an application.
How should you study Unified Communication automation?
Treat Unified Communication as a set of integration problems: discover the interface, authenticate, submit a valid request, interpret the response, and handle failure. The v1.2 blueprint specifically names UCM AXL SOAP automation, CTI APIs, Serviceability Perfmon, CDR, IP Phone Services, and Finesse REST APIs and Gadgets.
Begin with a comparison table of the named interfaces. For each one, record the platform function it supports, the protocol or interface style, the kind of data it exposes or changes, and the operational consequence of an invalid request. This forces you to distinguish an administrative automation task from a real-time control or monitoring task.
Build a small sequence around an API workflow without depending on live exam questions. For example, design the inputs, request structure, expected response, validation checks, logging, and failure path for an administrative UCM operation. The goal is not to memorize a payload; it is to understand how an automation client should behave when the service accepts, rejects, or partially processes a request.
Study CDR and Serviceability Perfmon as data and observability topics, not merely interface names. Ask what an automation script would collect, how it would identify malformed or missing data, and how the result could be separated from an authentication or transport failure.
For Finesse REST APIs and Gadgets, connect the API to the user-facing application layer. Sketch what data an agent-facing gadget needs, how it obtains that data, and what should happen if the API is unavailable. This makes the relationship between a backend service and a collaboration application easier to reason about.
A common mistake is to study UCM configuration screens while avoiding code and API documentation. Configuration familiarity helps, but it does not replace practice with requests, responses, authentication, error handling, and data transformation.
How should you prepare for Cloud Collaboration topics?
Cloud Collaboration is weighted at 25% and spans Webex REST APIs, administration, Python automation of spaces and memberships, bots, embedded and service apps, Webex Widgets, and Webex SDKs. Prepare by tracing how an application acts on behalf of a user, an administrator, or a service.
Separate identity and authorization from application logic in your notes. For every Webex automation exercise, identify who or what is making the request, which resource is being accessed, what permission is required, and how the script should respond when authorization is insufficient. This prevents a common error: treating every API failure as a Python bug.
Practice a complete spaces-and-memberships workflow at the design level. Define the intended resource, list the data the script must send, validate the response, and decide how the script handles an existing membership, a missing space, a duplicate request, or a temporary service failure. Keep test data controlled and avoid using real organizational information in learning projects.
Bots, embedded apps, service apps, Widgets, and SDKs should be studied by their integration role. Ask whether the component acts inside a user conversation, embeds collaboration capability in another application, provides a service identity, adds an interface element, or supplies a development toolkit. The distinctions are more useful than memorizing a catalogue of names.
Include asynchronous behavior in your preparation. An event-driven application may receive information later rather than obtain everything in the original request. Practice documenting the event, the handler, the validation step, and the action taken after the event arrives.
Do not assume that cloud automation is simply on-premises automation with different URLs. Authentication models, service boundaries, resource identifiers, rate behavior, event handling, and application packaging can change the design of a reliable integration.
How do Collaboration Endpoints fit the study plan?
Collaboration Endpoints is a separate v1.2 exam domain weighted at 20%, so it deserves its own study block rather than being absorbed into general Webex or UCM revision. Use Cisco’s detailed blueprint to identify the exact endpoint objectives, then connect each objective to an automation or integration use case.
A useful method is to map an endpoint workflow from discovery through operation and monitoring. Record how an application identifies an endpoint, what data it needs to send or retrieve, which service mediates the action, and what evidence would show that the operation succeeded.
Keep endpoint notes concrete. For each technology named in the official objective list, write one short explanation of the resource or behavior involved, one dependency, one likely failure condition, and one question you would ask before automating it in production. This exposes gaps more effectively than rereading product descriptions.
Avoid borrowing assumptions from unrelated device-management exams. The fact that an endpoint is visible to an administrator does not automatically mean that the same object, permission, or operation is available through the interface being tested. Check the blueprint and the relevant Cisco documentation for the supported automation boundary.
Because the supplied research does not reproduce every Collaboration Endpoints subobjective, do not create a private checklist from memory. Download or consult the official v1.2 exam-topics document when reviewing historical coverage, and use its wording to decide whether your notes address the required area.
What study sequence works for a mixed automation exam?
Use a dependency-first sequence: programming and API fundamentals, then one Unified Communication workflow, one Cloud Collaboration workflow, and finally endpoint integration and cross-domain review. This sequence reduces the risk of memorizing product terminology without being able to reason through an automation task.
Phase one should establish the foundation. Work through Git operations, API styles, synchronous and asynchronous patterns, Python fundamentals, virtual environments, and deployment components. Produce small artifacts: a version-controlled script, a documented request flow, and a troubleshooting checklist.
Phase two should concentrate on Unified Communication and Cloud Collaboration because each domain is weighted at 25%. Alternate the domains rather than completing one and forgetting the other. After each exercise, explain the authentication path, request format, response handling, error path, and security or deployment dependency in your own words.
Phase three should give Collaboration Endpoints a dedicated review block weighted to its 20% blueprint share. Use the official topic document to select objectives, then test whether you can connect endpoint behavior to an application workflow. Return to Network Programmability Foundation whenever a Python, Git, API, or deployment weakness interrupts the exercise.
Phase four should be diagnostic. Take a topic list and mark each item as explain, demonstrate, or unfamiliar. A topic marked explain but not demonstrate needs a practical exercise; a topic marked unfamiliar needs documentation-led study; a topic marked demonstrate needs a short, timed review rather than another passive reading session.
If your available time is limited, do not divide it equally across every product. Protect foundation work, prioritize both 25% domains, keep the 20% endpoint domain visible, and use the 10% foundation weighting as a minimum signal rather than a reason to skip it. These are preparation decisions based on the blueprint, not official passing criteria.
What should a practical lab or project contain?
A useful lab has a defined objective, controlled inputs, an observable result, and a failure path. Build small automation exercises around the blueprint domains instead of attempting an oversized collaboration platform project that is difficult to reset or troubleshoot.
For a foundation lab, place a Python client in a Git repository, run it inside a virtual environment, parse structured data, and log both successful and unsuccessful outcomes. Document the API style and whether the client waits for a response or handles an asynchronous event.
For a Unified Communication lab, model an API-driven administrative or monitoring task. Keep the exercise focused on request construction, response interpretation, validation, and recovery. If you lack access to a live system, use documentation and representative data without claiming that a simulated response proves production behavior.
For a Cloud Collaboration lab, design a spaces or memberships workflow with explicit identity and authorization assumptions. Add input validation, safe handling of duplicate or missing resources, and a clear record of what the script attempted. A useful review question is whether another engineer could understand the result from the logs alone.
For an endpoint lab, start with the exact objective in the official blueprint and define the boundary of the integration. Identify the endpoint resource, the controlling service, the application action, and the observable success condition. Do not expand the exercise into unsupported features simply to make it look more advanced.
The project should finish with a short incident review: what failed, how you isolated the fault, which evidence you used, and what change prevented recurrence. This develops the reasoning needed for automation work without depending on leaked or memorized exam content.
Which preparation mistakes waste the most time?
The most damaging mistake is preparing for an exam version without first checking whether it can still be taken. Cisco announced the 300-835 retirement timeline, and Cisco’s retired-exam policy says retired exams cannot be used for certification or recertification. Status verification comes before course selection or scheduling.
Another mistake is treating the blueprint percentages as a list of isolated facts. The 25% Unified Communication domain and the 25% Cloud Collaboration domain both depend on the 10% Network Programmability Foundation domain’s API and Python skills. Study the dependencies between domains, not only their headings.
Avoid memorizing API names without practicing the surrounding workflow. Knowing that an interface exists does not show that you can select the right request pattern, authenticate correctly, validate returned data, or distinguish transport, authorization, application, and deployment failures.
Do not rely on exam dumps, leaked questions, or answer memorization. They do not establish current exam availability, do not teach transferable automation skills, and cannot guarantee a passing result. Use official objectives, Cisco documentation, code exercises, and honest self-assessment instead.
Do not assume a course title is a current exam guarantee. Cisco’s CLAUI course was designed to prepare candidates for 300-835 and covered UCM, IP Phone Services, Unity Connection, Finesse, Collaboration Endpoints, Webex Teams, and Webex Meetings, but a historical course description cannot establish that the exam remains available or that its content has not changed.
Finally, avoid spending every study session writing code while ignoring documentation. Automation work depends on reading interface contracts, permissions, data structures, and operational constraints. Alternate implementation with explanation and review.
What delivery details are documented?
The original Cisco Learning Network overview lists 300-835 as an English exam delivered through Pearson VUE, and the v1.2 exam-topics document lists a duration of 90 minutes. These are historical or version-specific details; confirm current availability and registration information with Cisco before making a scheduling decision.
The original overview’s first test date was February 24, 2020. That date describes the historical launch information and should not be confused with a current appointment date or an indication that the exam remains open for registration.
The supplied official material does not establish a current price, question count, passing score, delivery-mode availability, retake rule, or current language policy beyond the original overview’s English listing. Those details should be checked directly in Cisco’s current registration and exam information systems rather than filled in from third-party sites.
If Cisco confirms that a legacy appointment is still relevant to your case, verify the exact exam code, version, provider, language, time allowance, and cancellation or rescheduling terms during the official booking process. Save the confirmation and compare it with the official blueprint version you studied.
How can you use Cisco’s CLAUI course information?
Cisco’s Implementing Automation for Cisco Collaboration Solutions course was designed to prepare candidates for 300-835 and covered Cisco UCM, IP Phone Services, Unity Connection, Finesse, Collaboration Endpoints, Webex Teams, and Webex Meetings. Use that scope as a way to locate learning gaps, not as a substitute for the v1.2 exam blueprint.
If you already have access to the course, turn each product area into an applied question: what can be automated, through which interface, with which identity, and how would you verify the result? Then compare your answer with the official exam topics and mark anything that the course does not address clearly.
Cisco states that the CLAUI course provided 24 Continuing Education credits toward recertification. Because credit policies and certification status can change, confirm the current applicability of any course credit with Cisco before purchasing or completing training for that purpose.
Course completion alone is not a readiness test. After each module, close the material and reproduce the workflow from notes, explain the failure modes, and make a small change to the code or design. If you cannot do that, schedule more practice before treating the topic as complete.
What should you do next?
First, verify the exam’s current status and whether Cisco recognizes any completed or planned attempt. The announced last day to test on 300-835 v1.2 topics was February 2, 2026, and Cisco’s policy says retired exams are unavailable for certification and recertification.
If an official booking path confirms an available attempt, download the applicable blueprint, build a domain checklist, and diagnose your foundation before spending most of your time on product-specific material. Prioritize Unified Communication and Cloud Collaboration at 25% each, then give Collaboration Endpoints its 20% domain allocation and maintain Network Programmability Foundation practice at 10%.
If no attempt is available, stop using 300-835 as a scheduling target. Use the v1.2 blueprint and Cisco’s historical course scope to identify automation skills you want to retain, then move to the current Cisco certification and exam-topic pages for a valid replacement route.
Keep a final evidence log containing the official status check, blueprint version, study objectives, lab results, and unresolved questions. That record helps prevent a common certification failure: preparing diligently for an exam that has already changed or retired.
Conclusion
300-835 was a focused automation and programmability exam for Cisco Collaboration environments, with substantial coverage of Unified Communication, Cloud Collaboration, Collaboration Endpoints, and programming foundations. Its announced retirement timeline makes verification the first candidate task. If Cisco confirms that the legacy exam is unavailable, do not schedule it or rely on old preparation promises; use the official current certification pages to choose the next exam. If an authorized attempt remains relevant, study from the v1.2 blueprint, practise complete API workflows, and measure readiness by what you can explain and implement rather than by memorized answers.
