Hey Vivek
I’m confused by your question, and perhaps our information itself is not clear. Let’s work this out together!
Am I right in understanding that you have a Twitter App; it has a callback URL that works; and you want to get a logged-in user’s email address?
If so, here are the basic steps:
- you should create a Twitter app with a server-side element, and a whitelisted callback URL in the dev dashboard
- you should implement the Sign-in With Twitter flow
-
after your user has signed in, you should call the
account/verify_credentials endpoint with the ?include_email=true parameter
- if you do not do this, email will not be returned
- if you have not reauthenticated your user since updating your app permissions for email access, you will not get an email address
If, as I alternatively read your post, you want to get access to a Twitter user’s address book for email matching; we do not support that use case.
Thank you.
