API testing

Test the contracts your product depends on.

Verify that services behave predictably across valid requests, invalid input, authorization boundaries, state changes and dependency failures.

DESIGNED FORPlatform and integration teams
Managed by TaskQA
In detail

APIs hold products together, but many failures appear only outside the expected request. TaskQA builds coverage from the contract and the business workflow, then challenges validation, authorization, sequencing, retries and error handling. Reports preserve request context while keeping credentials and sensitive data out of evidence.

What this includes
01

Contract coverage

We verify methods, schemas, required fields, types, status codes, headers, pagination and documented compatibility expectations.

02

Negative testing

Boundary values, malformed payloads, missing data, duplicate requests and unauthorized access are exercised deliberately.

03

State and workflow

Multi-step workflows validate creation, updates, transitions, idempotency and consistency across related endpoints.

04

Failure behaviour

Timeouts, dependency errors, rate limits and partial failures are assessed for safe, observable and useful responses.

What to expect

Clear scope. Useful detail.

01

Scenario coverage matrix

See the endpoints, roles, states and response classes covered in the cycle, including exclusions.

02

Sanitized technical evidence

Request and response context is preserved without placing secrets, tokens or personal data into shared reports.

03

Integration-level insight

Findings connect endpoint behaviour to the business workflow and downstream effect instead of stopping at a status code.

04

Ideal product moments

Use API testing for REST services, authentication, payments, webhooks, version changes and partner integrations.
