Context: I am using the [PHP] Gmail API and InboxSDK.
When sending a message (with Gmail API), I output the message sent object (reference here).
It contains info about message ID and Thread ID.
What is happening?
Id and ThreadID is the same (ok: because it is the first message in the thread).
But if I check the received mail with InboxSDK, i see a different ThreadID than the one returned by GMAIL API.
Example of what is going on:
I send a Test email via API.
When checking the thread ID with InboxSDK though...
We can see both Thread Ids are different.
Maybe I am doing something wrong, can you please help me out with this?
Note: I tried this multiple times with multiple google accounts. The issue is constant.
