REST API Design and Documentation

A versioned API contract with OpenAPI docs, worked examples and a mock server your partners can build against today.

Delivered in

9 working days

Revisions

One round, included

Ownership

Yours from day one

Overview

What this engagement is

Partners integrate faster when they are not reverse-engineering your endpoints. We design or document your API properly: consistent resource naming, predictable pagination and filtering, error responses that name the field at fault, and versioning that lets you change things later without breaking anyone. The OpenAPI specification is published with a browsable console and a mock server, so an external developer can write and test their side before your implementation is even finished.

Deliverables

What lands in your repositories

7 items
  • OpenAPI 3 specification covering up to 40 endpoints
  • Consistent conventions for pagination, filtering, sorting and errors
  • Published documentation site with request and response examples
  • Mock server generated from the specification for partner testing
  • Authentication guide covering keys, tokens and rate limits
  • Versioning and deprecation policy in writing
  • Postman collection for your support and partner teams

Outcomes

What changes once it ships

Partners integrate without a series of clarifying emails

Front-end work starts against a mock instead of waiting

Breaking changes become a planned event rather than an incident

Process

How the 4 stages run

  1. 01

    Review

    existing endpoints inspected, or requirements gathered if new

  2. 02

    Design

    conventions, resources and the error model agreed with your engineers

  3. 03

    Specify

    OpenAPI written, examples added, mock server generated

  4. 04

    Publish

    documentation deployed and walked through with your team

Booked most often by

  • Companies whose API documentation lives in a spreadsheet
  • Products opening up to partner or customer integrations
  • Teams whose front-end and back-end keep disagreeing about payloads

What we need from you

  • Access to the codebase or existing endpoint list
  • An engineer available for two design conversations
  • Any partner requirements or contractual constraints on the interface

These are collected in the technical brief that opens in your dashboard the moment payment clears. The clock starts when they arrive, not before.

Answers

Questions this engagement raises

Yes. Reading an unfamiliar codebase and writing the contract is a large part of this work.

Implementation is separate, though we often find small inconsistencies and fix them by agreement.

We do the equivalent with a schema, documentation and example queries. Same price.

This is engineering work, not a physical product — nothing ships and there is no stock to run out of. Delivery is to the working days stated above, into systems you control, and the refund terms set out what happens if we miss the date.
