Midaz and plugin compatibility - Lerian

Midaz application v4

Capability	Runs as	API surface
CRM	Unified Ledger module	`/v2` only
Fees	Unified Ledger module	`/v2` only
Pix and Bank Transfer	Separate plugins	See each plugin’s API guide

In Midaz application v4, the unified Ledger contains CRM and Fees as modules. Use their /v2 API through the Ledger. They are not separate services, ports, or plugins. The /v1 compatibility surface does not run Fees or Tracer. Before Midaz v4, Fees ran as its own service. Its earlier releases do not define Midaz v4 compatibility.

Upgrade order

Upgrade Midaz before you upgrade its plugins. Plugins call the Midaz APIs, so a plugin that is newer than Midaz can call an API that Midaz does not serve yet. To install or upgrade Midaz, see the Midaz chart README.
