get current thread id in gmail using google app script

问题

I am building a Gmail Add-On. I want to get the thread Id of current open email thread using Google Apps Script. I tried to figure out in Google Developers documentation for GmailApp. But nothing found relevant.

回答1:

You can retrieve messageId of the current message from e.messageMetadata.messageId of buildAddOn(e). Using this, you can retrieve threadId as follows.

var threadId = GmailApp.getMessageById(messageId).getThread().getId();

References :

• getMessageById()
• getThread()

If this was not what you want, I'm sorry.
