I'm trying to use Twilio Conversations for a project, and in order to just get a simple understanding of everything I'm trying to tinker it out in Postman first. I'm trying to create a conversation Participant there but I keep getting Error 5204 - Identity not Provided.
I've tried to give an identity as a parameter, or an element in the body, as well as the same for the two needed fields for an SMS participant.
So, the problem is not at Twilio because it works with cURL.
If you want to do it with Postman, select the "Body" tab and make sure you choose application/x-www-form-urlencoded
so the content-type header will automatically be set for you.
Then add the key/values pairs, but to create a (SMS) participant you only need to add a Twilio number and a participant number.
Just tried on my computer and it works no problem.
Update from @gehrlich: sounds like the keys are case sensitive!
