Template

User Story Template for API Products

API products serve developers as users. User stories must specify request/response contracts, error handling, rate limiting, and SDK compatibility.

This template adapts the standard user story format for API-first products where the interface is an endpoint, not a screen.

Template sections

4 sections covering the complete user story workflow.

01

Developer Persona

Replace the traditional user persona with a developer persona: language/framework, integration context, and experience level with your API.

02

API Contract

Acceptance criteria must include: HTTP method, path, request/response schemas, status codes, and rate limit behavior.

03

Error Handling

Specify error responses as first-class requirements: error codes for each failure case, response body format, and retriability.

04

Breaking Change Assessment

Every API story should assess: does this break existing integrations? If yes, what is the migration path and deprecation timeline?
