# Midaz CRM and Fees Engine integration contract

> Midaz guidance now uses the current CRM account-composition route and correctly describes CRM and Fees Engine as integrated components.

## Affects

***

Teams that create holder-owned Midaz accounts, configure Fees Engine, or use the Midaz CRM and fee documentation in deployment and operating runbooks.

## What changed

***

The enterprise-model guide now uses `POST /v2/organizations/{organization_id}/ledgers/{ledger_id}/holders/{id}/accounts` to create a holder-owned account. CRM and Fees Engine are integrated Midaz components, not standalone products or optional plugins. Fees are applied while Midaz creates a transaction; the fee-estimate operation remains a separate, package-specific preview.

These are documentation corrections that align the guides with the implemented contract. They do not announce a runtime release.

## Impact

***

**Classification: Action required.** Automation that uses the former holder-account `/v1` route must move to the documented `/v2` route. Deployment and setup material must not treat Fees Engine as a plugin to enable.

## What you need to do

***

<Steps>
  <Step>Replace the former holder-account `/v1` call with the documented `/v2` route, including its ledger identifier.</Step>
  <Step>Review setup and deployment runbooks: configure Fees Engine fee packages in Midaz rather than enabling a Fees plugin.</Step>
  <Step>Use the estimate operation only to preview a specific package; validate fee application through transaction creation.</Step>
</Steps>

### Deadline

Complete the route and runbook review before the next production account-opening or fee-configuration change.
