Actually, I have a contact form with multiple fields and 2 upload files, that once submitted, send a Form Post to a 3rd party API via the Webhooks plugin, the mapping of the fields is working great. The problem is the 3rd party is waiting for files and it get instead upload urls from file fields, so that is not working.
I read the doc, but I’m not sure how to achieve my goal with Gravity Forms hook, this current scenario is not documented as example.
My 3rd party API saved correctly the base64 encoded file into the “test” field (I was able to manually decode it and get back my file), however, the other two fields that are file field didn’t accept base64 string. I tried with postman, it accept files, but not base64 string. Is there a way to provide something similar to the upload HTML field to the API?
