I need to send a custom value of true. It appears that it is sending as a string. The 3rd party API needs a true boolean. I also tried sending 1. Neither “true” nor “1” worked.
When I send using reqbin, I have successfully communicate with the 3rd party API. The only difference in my post is that I use true on reqbin and I use “true” with GravityForms+Webhooks.
