API Contract Assurance

Contract testing that fails the build as soon as an endpoint alters its response structure, so server releases no longer break the apps and partners depending on them.

01 / Overview

What this service delivers

Consumers of an API seldom fail because the service is offline; far more often a field has silently become nullable. Contract testing exists to catch exactly that. Our suite validates every response against its schema, checks status codes and error formats, and applies the access rules that count, so one customer can never see another customer's data. It runs on every pull request, which means a breaking change shows up as a failed build within your own pipeline rather than as a support ticket raised by a partner.

02 / Deliverables

What you receive 7 items

  1. 01Schema-validated contract tests covering up to 40 endpoints
  2. 02Checks on status codes, headers and error format for every endpoint
  3. 03Authorisation tests confirming role limits and per-object access controls
  4. 04Negative scenarios for malformed requests and missing fields
  5. 05Pipeline integration that identifies precisely which contract failed
  6. 06Stored schema snapshots, so any accidental change is visible in a diff
  7. 07Guidance on extending the suite as new endpoints are introduced

03 / Fit

Who it suits, and what we need from you

Ideal for

  • Teams whose shipped mobile app struggles to keep up with server changes
  • Products with an API used by external partners
  • Back ends left untouched because nobody can predict the fallout of changes

What we need from you

  • API access, plus credentials for every user role
  • Any existing API specification in machine-readable form; it is optional
  • An engineer who can rule on intended behaviour wherever it is unclear

You share these through the technical brief in your dashboard after checkout.

04 / Outcomes

What changes for your team

  • 01

    Breaking changes fail in the pipeline instead of on a user's device

  • 02

    Refactoring becomes safer with contracts actively enforced

  • 03

    Your shipped mobile app keeps working when the server evolves

This is a remote engineering service, so nothing is shipped physically. Work is delivered into systems you control. Read delivery & handover and refunds & cancellation for the full terms.
