Is it possible to pass constant form parameters (ex: campaign codes) through the WebHook to a proprietary database? URL parameters aren’t working. The record is pushed through with empty fields.
Rest assured, if you’re using an Unbounce form and hidden fields the WebHook will POST all data. I submitted an HTTP inspection test. Note the utm_term and utm_campaign being POSTED in both XML and JSON here.
Dependent on your WebHook script, and how it’s been written to accept the response, there could be a number of factors at play. We have a support ticket open for you, be sure to check your email I’ll be following up there.
