# G2P Program Payment (Payment Interoperability Layer)

### Module name

g2p\_payment\_interop\_layer

### Module title

G2P Program Payment (Payment Interoperability Layer)

### Technology base

[Odoo](https://www.odoo.com/)

### Functionality

This module extends the core G2P Payment Manager functionality to integrate with an external payment interoperability layer.

* Sends payment information for designated payment batches to the interoperability layer API.
* Supports automatic batch creation based on program cycles and configurations.
* Maps beneficiary information (payee IDs) to the interoperability layer format using configurable rules.
* Handles successful disbursements, updating payment statuses and reconciling records.
* Provides information on completed payment processes through notifications.

### Design notes

* Built upon the existing `g2p.program.payment.manager` class, inheriting its core functionalities.
* Utilizes the Odoo inheritance pattern for modularity and maintainability.
* Relies on configurable settings for payee ID mapping and automatic batch creation.
* Integrates with the external interoperability layer through its configured API endpoint URL.

### Relationships with other entities

* **Internal Interactions:** Collaborates with the `g2p.program.payment.manager` class for overall payment coordination and batch management.
* **External Integration:** Connects to the external payment interoperability layer API for secure and efficient disbursement execution.

### Dependencies
