# Integration

**Global Collections Integration** is the technical reference for connecting a merchant system to the NeoX Global Collections service over REST APIs.

This section covers everything required for a complete integration:

* **Getting started:** Service [Introduction](/docs/global/global-collections/integration/introduction.md), [How To Register](/docs/global/global-collections/integration/how-to-register.md), and the [Security Method](/docs/global/global-collections/integration/security-method.md).
* **Authentication:** The [API authenPlatform](/docs/global/global-collections/integration/api-authenplatform.md) OAuth 2.0 token endpoint used to obtain the Bearer token for every other call.
* **API groups:** Sub-Merchants, Files, Accounts, Virtual Accounts, Trade Orders, Collections, Refund Requests, Beneficiaries, Payout Requests, and FX.

All endpoints share a common base URL, authentication scheme, and response envelope — see [Security Method](/docs/global/global-collections/integration/security-method.md) before calling any API.
