Hi,

Inherit the payment.provider and add this code

@api.model

def _get_payment_method_information(self):

"""Override to add createtest payment method information to the

existing methods.

"""

res = super()._get_payment_method_information()

res['createtest'] = {'mode': 'unique', 'domain': [('type', '=', 'bank')]}

return res
After completing these steps, your custom payment provider should appear on the list of available payment providers, and you can set the journal to "bank" as specified in your code. 

Hope it helps

Reverse engineering doesn't help. My custom module (payment provider) works and I can implement post-processing steps with it. But the main issue is it doesn't connect with account_payment_method table and I cannot assign payment journal. That means upon activating my custom payment provider it doesn't perform some silly steps that are eiher hidden from community or this is lacking some major support.

Hi,

There is no official documentation for the same. But you can refer to existing payment providers and develop your own provider. Other than default payment providers you have a lot of third party payment providers which is available for free in the odoo app store, to which you can look to understand how the module is developed and working.

Thanks
