# Plan your integration.

Canonical page: https://finanzer.ai/developers/docs

> Plan a Finanzer integration around customers, accounts and financial operations. Review the object model, testing needs and API contract to request.

Start with the customer, the financial operation and the information your systems need. These guides explain the platform model before you request access.

## Choose your starting point.

### Understand the objects

Map customers and businesses to accounts, balances, quotes, transfers and cards.

[Explore API domains](https://finanzer.ai/developers/api)

### Plan a test environment

Identify the supported scenarios and permissions your integration will need.

[Prepare for sandbox access](https://finanzer.ai/developers/sandbox)

### Follow the operation

Plan how your system will consume events and reconcile the final result.

## What to request before coding.

The production contract must define the actual endpoints, schemas, authentication and permissions. These concept pages do not replace that specification.

### Your use case

Describe the customer type, markets and operations you want to support.

### The API contract

Request the current version, supported domains, authentication requirements and error reference.

### Access and testing

Confirm credentials, environment, limits and the steps required before production access.
