API Automation Testing

Catch breaking API changes before your integrations do

We build automated test suites for your REST, SOAP, GraphQL, or WebServices APIs and wire them into CI, so a bad deploy fails a pipeline instead of a customer’s workflow.

Why ThoughtCoders
  • US, Canada & UK overlapWorking hours planned around your team, not just ours.
  • One point of contactA named lead owns the engagement end to end — no ticket queue.
  • NDA on every engagementSigned before we see a single ticket or line of test data.
  • Scale up or down monthlyNo multi-year lock-in — resize the team as the release calendar changes.

Who this is for

Engineering teams shipping APIs that other services, partners, or a mobile app depend on — with little or no automated coverage today.
Especially useful if the way you find out about a breaking change is a support ticket, not a failed build.

What you get

  • 25–40 automated test cases covering core endpoints, auth flows, and error handling
  • A version-controlled test suite (Postman/Newman, REST Assured, or your preferred stack) structured by service, not by ticket
  • CI wired into GitHub Actions (or your existing Jenkins / Azure DevOps setup) so tests run on every pull request
  • One load/performance pass on your 3 highest-traffic endpoints using JMeter
  • HTML and JSON test reports after every run
  • A 60-minute handover session walking your team through the suite and how to extend it
  • 2 weeks of post-handover support for flaky tests or environment issues

Timeline & process

Week 1

Discovery & scoping

Review your API docs or OpenAPI/Swagger spec, agree on which endpoints matter most, and get access to a staging environment.

Week 2

Test design & framework setup

Write test cases against agreed acceptance criteria and stand up the automation framework and folder structure.

Week 3

Automation & CI wiring

Implement the suite, connect it to your CI pipeline, and get the first full green run.

Week 4

Handover & stabilization

Fix flaky tests, hand over reports and documentation, run the walkthrough call, and start the support window.

What we need from you

  • Access to a staging or sandbox environment with realistic test data
  • API documentation or an OpenAPI/Swagger spec — or 30 minutes with the engineer who knows the endpoints
  • Test credentials and API keys for each environment we’ll run against
  • One walkthrough call with your team before we start

Proof, not promises

Not in scope, so there are no surprises

  • Full penetration testing or a formal security audit — we flag obvious issues, but this isn’t a pentest engagement
  • Coverage for endpoints that aren’t reachable from a staging or sandbox environment
  • Load testing beyond the endpoints agreed at kickoff
  • Ongoing maintenance after the 2-week support window — available separately as a retainer

Questions we get asked

Do we own the test suite after the engagement, or is it locked to your team?

It's yours. The suite is version-controlled in your own repo from day one, and the handover session walks your team through extending it — there's no dependency on us to keep it running afterward.

What if our API doesn't have OpenAPI/Swagger docs?

Common enough that it's built into the process — 30 minutes with the engineer who knows the endpoints gets us to the same starting point as a spec would.

Will this catch things a load balancer or WAF issue outside the API itself would cause?

No — this suite tests your API's own logic, auth, and error handling. Infrastructure-level failures (load balancer misconfig, WAF rules, DNS) sit outside this scope; flag it at kickoff if that's a known risk area and we'll tell you honestly whether it belongs in this engagement or a separate one.

Can your team work inside our existing CI setup, or do we need to switch tools?

We wire into what you already run — GitHub Actions, Jenkins, or Azure DevOps — rather than asking you to adopt new infrastructure for our sake.
