Midaz and plugin compatibility - Lerian

Midaz application v4

Capability	Deployment model	API surface
CRM	Unified Ledger module	`/v2` only
Fees	Unified Ledger module	`/v2` only
Pix and Bank Transfer	Separately released plugin charts	See each chart and API guide

In Midaz application v4, the unified Ledger contains CRM and Fees as modules. The Helm chart has its own version line. Use their /v2 API through the Ledger. They are not separate services, ports, plugins, or Helm releases. The /v1 compatibility surface does not run Fees or Tracer.

Chart surfaces

CRM is a module inside the midaz-helm chart. You enable it with the crm values block. No CRM chart exists. The plugin-fees-helm chart remains published for releases that predate the unified Ledger. Its versions do not define Midaz application v4 compatibility.
