Welcome to our API Reference

Lerian APIs offer reliable, scalable, and secure access to everything the platform provides, from onboarding workflows and ledger management to plugins for authentication, fees, CRM, and reporting.

This section is your guide to every API Lerian offers. Whether you're integrating Midaz directly or building custom plugins, you'll find what you need here.

❗️

Important

You’re viewing the documentation for the latest version of Midaz and its plugins. If you’re working with an earlier release, check out the legacy docs to avoid version mismatches.


Key highlights

  • RESTful and predictable: All endpoints follow standard HTTP methods and status codes.
  • Consistent formats: Requests and responses use JSON, with clear typing and structures.
  • Explicit versioning: APIs are versioned to prevent breaking changes.
  • Plugin-first architecture: Many features are available as modular plugins, each with its own set of APIs.
