I have had a fair bit of success in using webhooks and the Mindbody API but I have hit a wall when it comes to uploading a file to a client.

I have created a Custom Webhook and added the correct fields from

I can make the code work in Postman and upload a test PDF with no trouble.

I get a timeout error (504) in Zapier. I have also tried to use a code block with Javascript to post the data but that times out at 30s.

I have attached a screenshot of my Zap and obviously blanked out keys. BASE64 is where I’d put the PDF data in once it’s converted in a previous step.

Am I missing something? I’d really appreciate any help here!

Thank you!
