Product API Server

A well-documented REST API with login, background jobs and test coverage, so your web or mobile developers can start building against it straight away.

  • 22 working days
  • Scope published below
  • GST included
  • Ref. CZ-SW-103

Overview

Decisions you make about your back end today determine how painful product changes become next year. We write a service designed to last, with tidy resource controllers, validated input, migrations that apply without errors to an empty database, background queues for slow tasks and tests where they add real value. You get a machine-readable specification covering each endpoint, built on the relational database you prefer, so your client developers always know exactly what to send and expect.

What you receive

  1. Up to 30 REST endpoints, each one fully documented
  2. Token authentication with roles and a check on every permission
  3. Seed records, versioned migrations and a schema that runs locally
  4. Background and scheduled jobs for emails, exports and slow tasks
  5. API specification file plus an interactive console for exploring endpoints
  6. Automated tests covering login, validation and the key business flows
  7. Deployment instructions and a documented list of all environment variables

How it runs

  1. Step - 01

    Contract

    We model your domain, settle every endpoint and publish the specification before coding.

  2. Step - 02

    Build

    Endpoints are delivered feature by feature, each with its tests written alongside.

  3. Step - 03

    Integrate

    Client developers start building on staging while we finish the remaining endpoints.

  4. Step - 04

    Harden

    We run a load check, review error handling and rehearse the deployment.

Timeline: 22 working days, counted from the day we receive what we need from you.

Is it a fit?

A good match for

  • Mobile apps currently relying on a spreadsheet instead of a real server
  • Teams replacing an old server codebase everyone avoids touching
  • Products planning a second client app on the roadmap

What we need from you

  • Your data model, or one hour with the person who knows the business rules
  • A choice of hosting and database, or our recommendation
  • Representative sample records, especially the awkward edge cases

Why it helps

  • Client developers can start immediately against an agreed API contract
  • Test coverage that lets future developers make changes with confidence
  • Slow operations run in background queues, keeping requests fast

Questions

Yes. Every endpoint carries a version prefix from the start, so breaking changes can be introduced without disrupting a mobile app that is already released.

Whichever relational database you prefer. If you have not decided on hosting or the database engine, we will recommend an option that suits your product and team.

We configure the hosting environment and give you every credential. Ongoing hosting and maintenance are not part of this scope and would be arranged separately.
