# How To Register

Before calling any Global Collections API, the Merchant must activate the service and obtain API credentials on the Merchant Portal.

**Step 1:** Log in to the Merchant Portal.

**Step 2:** On the right pane, choose the **Global Collections service**, click the **START REGISTRATION** button, then click **SUBMIT** on the confirmation popup.

**Step 3:** Complete the Merchant KYB review. NeoX (with the partner provider) verifies the master merchant before the service is enabled.

**Step 4:** Retrieve the API integration credentials.

* Open the **Profile** section on the Merchant Portal.
* Copy the **client\_id** and **client\_secret** — these are used by the [API authenPlatform](/docs/global/global-collections/integration/api-authenplatform.md) endpoint to obtain a Bearer token.

**Step 5:** Configure the webhook to receive event notifications (recommended).

* Enable **Use APIs**.
* Fill in the **URL to receive notifications** for Global Collections events.
* Fill in the **Secret Key** — used to verify the `secureHash` of each webhook payload.
* Select the event **Type(s)** to subscribe to. See [Event Notification](/docs/global/global-collections/integration/event-notification.md).

**Step 6:** Generate the encryption key pair for sensitive payloads (if applicable).

* Generate an RSA key pair and upload the **public key** on the Merchant Portal.
* Keep the **private key** secret — it is used to decrypt any sensitive data returned by the service.

Once the service is **ACTIVE** and credentials are issued, proceed to [Security Method](/docs/global/global-collections/integration/security-method.md).
