The path to APV-300

Developers who already call APIs from code and now run them in production. Three courses, taken in order; finish one and its badge is yours, finish all three and the exam is waiting at the end. It builds on APV-100 and the Associate paths.

Skills measured

Three skill areas, weighted equally

Each course is one skill area, 10 questions each, drawn fresh for every attempt.

Resilient API Calls

33%
  • Classify transport, HTTP, envelope and per-item failures and map each to one action
  • Bound retries with an overall deadline, a retry budget, full jitter and Retry-After
  • Stop a failing upstream from eating credits and latency with a circuit breaker
  • Pace many workers under one per-minute limit and stop cleanly before credits run out
  • Make queue consumers idempotent with operation-derived keys and the outbox pattern

Scale and Cost Control

33%
  • Build canonical cache keys and add single-flight, stale-while-revalidate and negative caching
  • Plan, send and reconcile batch requests, re-queueing only the rate-limited items
  • Run a 100,000-row enrichment job that checkpoints, resumes and stays under the rate limit
  • Merge paginated results without duplicates or reordering, and know when a listing changed under you
  • Estimate a job's cost before it runs, enforce budgets per feature or tenant, and alert on burn rate

Operate Integrations Securely

33%
  • Issue, scope, inject and rotate API keys per service and environment without downtime
  • Verify HMAC-signed webhooks over the raw body with a replay window and constant-time comparison
  • Log every API call as structured data with credits, latency and request identifiers, and no secrets
  • Alert on error classes and credit burn, and hand support the identifiers that find your call
  • Test integrations with pure units, recorded fixtures and bounded live contract tests in CI

What to expect

How exam APV-300 works

Three kinds of question

Most are multiple choice: a scenario, a snippet of code or a response, and four options. A few are hands-on: the exam shows you a real API request, you run it, and type the value from the live response. Those runs are free and don't use your credits.

Write code that passes tests

3 questions ask you to write a short JavaScript function, such as a retry decision or a signature check. Run it against the examples as often as you need. When you submit, it runs against hidden tests on our side, and it counts only if it passes all of them.

Hands-on answers need a real run

A hands-on answer counts only if you ran its request during the exam. Running the call is the skill being measured.

Timed, open book

You have 90 minutes from the moment you start. The lessons and the docs are fair game, which is how you'll work on the job anyway.

A score report, pass or fail

Scores are out of 1000 and 700 passes. Pass or fail, you get a report of how you did in each skill area, saved to your account to print or keep as a PDF.

Retakes

If you don't pass, you can retake the exam after 24 hours. After two attempts in a row without a pass, the next one opens after 7 days.

Your credential

Pass and you're issued a credential ID with a public verification page, one-click LinkedIn and a shareable transcript. It's valid for three years, and renewal is free.

Certification questions.

About APV-300 and the credential.

Talk to the team →
Is the exam proctored?
No. It's an open-book online exam. The hands-on questions keep it honest: an answer only counts if you ran its request during the exam.
Does the certification expire?
Yes. Advanced certifications are valid for three years from the date you pass, so the credential reflects the platform as it is now. Renewal is free: from six months before the expiry date until six months after it, pass a 15-question, 30-minute assessment and the same credential ID is valid for another three years. Renewing early doesn't cost you any time.
Does it cost anything?
No. The courses, the exam and the credential are free, and the exam's hands-on requests don't use your credits.
Do I need another certification first?
No, it isn't required. This path assumes an Associate certification, or the HTTP, JSON, error handling and key safety that APV-100 covers. If any of that is new, start with APV-100.
Can I change the name on my certificate?
You set the name when you start the exam. If it needs correcting after you've passed, contact us from the account that holds the credential.

Each one is its own three-course path and exam.
