API sprint OpenAPI template
Use this template to make an API sprint concrete before implementation starts.
Template sections
The template is intentionally short so business and engineering reviewers can agree the API boundary quickly.
- Endpoint purpose
- Auth and permissions
- Request example
- Response example
- Failure behavior
- Handover owner
Why OpenAPI helps early
An OpenAPI-style template forces the team to name the contract before implementation drifts. It makes request shape, response shape, errors, ownership, and handover reviewable.
- Payload examples
- Auth assumptions
- Error responses
- Rate limits
- Owner for each system
What to decide before build
The first API sprint should not start with code. It should start with the business action the API supports and the conditions that make the handoff safe.
- Triggering event
- Source system
- Target system
- Retry behavior
- Logging and alerting
API template output
- Contract draft: Endpoint, method, payload, response, auth, and error examples.
- Integration notes: Source system, target system, owner, retry logic, and logging assumptions.
- Test examples: Happy path, missing field, permission failure, duplicate request, and timeout behavior.
- Handover notes: Repository, environment, secrets, runbook, and next endpoint candidates.
Preguntas frecuentes
- Do we need a complete OpenAPI spec for a sprint?
- No. A lightweight OpenAPI-style draft is enough to align scope and avoid ambiguity before implementation.
- Can we start without API access?
- Yes, with sample payloads or exports, but live access should be treated as a delivery risk and validated early.
