Integration guides

Practical, task-oriented guides to integrate the Guidis Reinf Reinf API and operate EFD-Reinf with less manual rework.

A differentiator of the Reinf API is that it can be consumed by AI agents: Claude Code, Codex and your own automation can read the assessment files on the user machine (XML, PDF, Excel, CSV and supporting documents), organize the submission data and transmit EFD-Reinf events through the integration.

Available guides

• Use Claude Code to prepare EFD-Reinf submissions - an assisted flow to read the assessment files, organize the submission and confirm doubts before transmitting.
• Use Codex to automate EFD-Reinf via API - executable automation outside the portal, with a technical credential and public OpenAPI.

Before you start

Check the Reinf API documentation and authentication to generate the API key and exchange it for an access token at POST /api/integracao/token.
