# Mortgage CRM API Overview

Welcome to the Mortgage CRM API reference. This section covers the core concepts you need before diving into endpoints.

## Base URL

`https://mortgage-crm.universal.rollout.com/api`

## Authentication (at a glance)

All requests require an `Authorization` header with a Bearer token (your `authToken`).

For Mortgage CRM endpoints that operate on a connected account, include `X-Rollout-Credential-Id` as well.

## Write behavior and propagation

Writes apply only to the system tied to the credential you provide in `X-Rollout-Credential-Id`. Rollout does not automatically propagate writes to other systems. If you need multi-system sync, call each credential explicitly or use Sync to DB plus your own orchestration.

## Response shape

List endpoints typically return a data array plus a `_metadata` object with pagination details like `offset`, `limit`, `total`, `next`, and `nextLink` when available.

## Next steps

* Read **Authentication** for header details and example requests.
* See **Pagination** for how list endpoints are navigated.
* Review **Errors** for status codes and error payloads.
