OpenAPI Specification

Import the SheetsToLabels Business API contract into API clients, SDK generators, and connector builders

The OpenAPI 3.1 specification is available at:

https://sheetstolabels.com/openapi.json

Download the OpenAPI JSON to import the API into Postman, Insomnia, compatible SDK generators, or custom-connector tooling.

The specification includes:

  • Bearer API Key authentication.
  • PDF generation with single, preset, and manual layouts.
  • Idempotency-Key and integration-source headers.
  • Binary application/pdf success responses.
  • Structured application/problem+json errors.
  • API-ready template discovery and variable metadata.
  • Avery and APLI-compatible print-layout preset discovery.

Generated clients must preserve the successful response as bytes or a file. Do not configure a generated client to parse every response as JSON.
