I'm trying to do some automation on a shopping platform to automatically send messages when order is received. However I realise that i'm getting Response 422 when there is no conversation existing between me and the buyer. If there is a conversation, it will be fine getting 200.
I tried to use the exact same headers and body in Postman and whenever I try to change the buyer ID to the buyer without any existing conversation, i'm getting 422 again.
Is there any possibility that I could make it go through?
