Early access
- Portal for the tax team routine
- Reinf API for integrations, automation and agents
- Receipts, protocols and proofs in the same platform
Portal or API
The same platform to operate through the interface, integrate by API or combine both.
API integration
Connect systems, automation and agents to the same EFD-Reinf flow, with authentication, messaging, webhooks and reports.
Combined use
Use the API for volume and automation, and the portal for tracking, exceptions, review and operational proof.
How it works
From registration to proof, without breaking your team routine.
Register taxpayer and certificate
Register the taxpayer, the A1 certificate and the period once - and go straight to the events.
Validate and submit
Review events, operate in bulk and track batches, receipts and protocols in the same flow.
Prove and follow up
Have reports, receipts and protocols at hand, without rebuilding the proof outside the system.
Core modules
Everything your team needs to submit, track and prove EFD-Reinf.
Taxpayer and certificates
Register the taxpayer, keep A1 certificates active and never mix company, period or environment between submissions.
Events and submissions
Prepare, review and transmit events without scattering the operation across parallel screens and controls.
Portal, API and messaging
Operate through the interface or the Reinf API, with webhook and messaging aligned to the same period and history.
Reports and proofs
Check the receipt, protocol, R-2000 and R-4000 analytics and the monthly proof without leaving the period.
API integration
When your operation needs integration, the API uses the same platform base.
The Reinf API covers registrations, event submission, EFD-Reinf messaging, webhooks and reports. The portal remains available to track exceptions, review receipts and prove the operation whenever the team needs it.

Frequently asked questions
Quick answers to the most common questions before you try the product.
Is Guidis Reinf a platform or only an API?
Guidis Reinf is an EFD-Reinf platform. The operation can run through the portal, the Reinf API or both, always with submission, messaging, receipts, protocols and proofs in the same flow.
Can I use Guidis Reinf without integrating by API?
Yes. The portal lets you register taxpayers, operate events, track batches, check receipts and access proofs without depending on your own integration.
Can I combine portal and API in the same operation?
Yes. Many routines use the API for volume, automation or agents, and use the portal for review, exceptions, tracking and proof.
Who is Guidis Reinf a best fit for?
It fits accounting firms, business groups and operations that already feel the pain of event volume, proofs and traceability in EFD-Reinf.
What can I test in the 30-day free trial?
You choose the plan you want to test, activate access by email and can use the full system for 30 days to register taxpayers, operate events and track receipts before deciding to subscribe.
What does the API cover today?
The API covers authentication, registrations, event submission, messaging, webhooks, receipts and operational tracking. It can also be used by Claude Code, Codex and your own agents to read the assessment files on the user machine, organize the submission and transmit EFD-Reinf events through the integration.
Can I use Claude Code, Codex or my own agents with the API?
Yes. You create the API credential, gather the assessment files on your machine and can use Claude Code, Codex or your own automation to read XML, PDF, Excel, CSV and supporting documents before organizing the submission. When there is a gap or divergence, the flow can ask for confirmation before transmitting.
Does Guidis Reinf reduce the dependency on manual e-CAC lookups?
Yes. The product centralizes submission, tracking, receipts, protocols and EFD-Reinf proofs in the same operational flow. In compatible scenarios, this reduces the need for recurring manual lookups in the e-CAC outside the platform.
