Fetch 'xhr' response when “Send” button is clicked in gmail

Question

I am making CRM for Gmail.

I want to get the unique \"email id\" in my chrome extension from the \"xhr\" response when \"Send\" button is clicked. I have not overridden

Answer 1

After searching for a week, I got a way to get the unique emailID.

When email is sent, a link is displayed - "Your message has been sent. View message".

View Message is a link. If you inspect this link, you will get a span element. It has an attribute 'param', which contains the emailID.

I fetched emailID from there and passed it in request to gmail API to get the email data.

I know it is not a permanant solution, but working for me as of now. If someone knows some other solution, please share.
