Hey @kohei! Daniel from Customer Support Engineering here
It looks like the hash value you’re passing here doesn’t match the one that’s expected from Intercom. I know you mentioned you checked out our hash calculator - can you ensure that you are using the correct token that’s associated with the workspace (your TEST workspace will have a different one) and you have employed the correct hashing algorithm? Let me know if so, and we can escalate this to the Messenger team if need be
Ive got this exact problem. Im on my test environment, using the correct appId and secret key. The generated hash is identical to the one generated in the Intercom test tool. Still, I get the error “Invalid user_hash”. The answer above is not an answer.
