Base64 Encoded Webhook Data

Base64 Encoded Webhook Data

I have my merchant services provider (Braintree) sending a webhook to Flow when a disbursement is made. The webhook payload is Base64 encoded, and the Deluge function for decoding doesn't seem to work with the string I have.

The webhook is being sent and received properly. The raw payload data is sent in URL encrypted format, which the receive webhook functionality from Zoho interprets and makes available as a variable as below:

Through testing with a B64 decoding tool, I realized that the "\n" separators were interfering with the decoding. So I tried to use the 'remove' Deluge function to eliminate them.

If I execute the function from the Deluge composing window, the \n separators are removed in the output. However, when I put that same function in a Flow and re-send the test webhook, the output of the function still has those "\n" values present.

This seems to be interfering with the zoho.encryption.base64Decode function within Deluge. It can't decode without the "\n" separators removed, but I'm not seeing how using the .remove string function doesn't seem to be the way to remove them.

Any suggestions for how to proceed?
