Developer access

Build document workflows with DocuStitch.

API access is designed for teams that need repeatable PDF operations outside the browser interface. This page documents the current surface area, request model, and integration expectations.

Request API access View endpoints

Scoped processing

API workflows should use isolated jobs, explicit retention rules, and clear limits per route.

Predictable endpoints

Common document operations are exposed as simple POST endpoints with multipart file inputs.

Infrastructure path

Unlike local browser tools, API requests necessarily use server-side processing and should be labeled accordingly.

Authentication

All API requests require a Bearer token. Request access from the Enterprise page.

# Include in all requests
Authorization: Bearer YOUR_API_KEY
