# Integrator Registry

The **Pay-Connect Integrator Registry** is a central system used to register and manage all integrators connecting to Pay-Connect services.

Each integrator must be registered before using any Pay-Connect APIs or App2App integration.

After registration, the integrator receives a **unique Integrator ID**. This ID is required in all API requests and integration flows and is used by Pay-Connect for identification and validation.

## Why registration is required

* Unique identification of every integrator
* Validation mechanisms to ensure only authorized systems can interact with Pay-Connect
* Operational control and monitoring of integrations
* Improved security and traceability across API usage and App2App communication

<Note>
  Requests that do not include a valid Integrator ID may be rejected.
</Note>

## How registration works

Registration is handled by the **Pay-Connect support team** as part of the onboarding process.

<Steps>
  <Step title="Submit integration request">
    Submit an integration request to Pay-Connect.
  </Step>

  <Step title="Registration by support team">
    The support team registers your system in the Integrator Registry.
  </Step>

  <Step title="Receive Integrator ID">
    You receive your **Integrator ID** and environment details.
  </Step>
</Steps>

<Note>
  No self-service registration is required.
</Note>

## Using the Integrator ID

Include your Integrator ID in every request, as specified in the API reference.

Example:

```
Header: X-Pay-Connect-Integrator-Id: YOUR_INTEGRATOR_ID
```

For [**App2App Integration**](/pay-connect/app2app-integration/introduction), the Integrator ID must also be included in the integration parameters.
