# Lerian product journeys

> Journeys that combine Lerian products, such as Midaz and Tracer, into one business flow.

These diagrams show how Lerian products work together in a business journey. They describe the behavior of our own products and APIs, so the product documentation and the API reference are the source for every step. Lerian supports these flows as part of the products.

## Journeys

***

**Midaz**

* [Create accounts and transact in Midaz](/en/diagrams/lerian-products/midaz-create-and-transact): From organization and ledger to a posted transaction in Midaz.

**Tracer**

* [Validate a transaction before the ledger](/en/diagrams/lerian-products/tracer-validate-before-ledger): How Tracer evaluates a transaction and returns ALLOW, DENY or REVIEW before Midaz posts it.
