Odoo version 13 -
I have created a payment for an invoice. I want to confirm the payment and use Authorize.net for the payment.
However, after I click 'confirm' on the payment, I get 502 Bad Gateway.
I have used the API LoginID and API TransactionKey.
I am not sure how should I use the Client key (it is mentioned in the document but doesn't talk about how to use it)
Also, is client key the problem or something else?
