I went into the UI for a contact property, checked multiple options for a checkbox property, then did a GET for that contact and looked at the format. I’m going to be updating the documentation over the next few days to provide some examples of this.
Thanks for your response. While this does work when you update a contact directly (I can confirm as well), it doesn’t work for what this discussion thread is about: Sending multi-checkbox values through the Forms API.
Can you give it a try and let me know if sending multiple values through the Forms API works for you?
I reviewed the UI for a contact property, selected multiple options for a checkbox property, and performed a GET request to inspect the format. Over the next few days, I will be updating the documentation to include examples based on this process.
