Hi,

Since there is no official Odoo PayMongo module available for Odoo version 10, you will need to use a third-party module or create a custom module to integrate PayMongo as a payment acquirer in your Odoo 10 eCommerce platform.

Here are the general steps you can follow to integrate PayMongo as a payment acquirer in Odoo 10:

1. Create a custom module or use a third-party module that supports PayMongo integration.

2. Configure the PayMongo API keys and other necessary information in the payment acquirer configuration settings.

3. Customize the payment process flow to redirect the user to the PayMongo payment page when the payment method is selected.

4. Handle the payment status response from PayMongo and update the order status accordingly.

5. Test the payment process in a staging environment to ensure it works correctly before going live.

Hope this will help you

Thanks
