A processing channel contains a set of configurations used when processing a payment. If you have complex processing requirements, we may have set up multiple processing channels for you during your onboarding.
You can process API requests for different processing channels using the same API key. If you choose to do so, you must specify the processing channel in your payment request moving forward.
To edit an existing API key, your user must have a custom role with the Edit or delete keys permission.
Follow these steps to add a processing channel to an API key:
-
Log into the Dashboard and navigate to the Developers section.
-
Under the Keys tab, select the API key you wish to update.
-
On the Key details page, click Update key.
-
In the Processing channels section, select the channel you want to add to the key.
-
Select Save changes to confirm the update.
