Introducing HTTPS for Yahoo Mail APIs

by Shiv Shankar, Product Manager, Yahoo Mail

As part of our ongoing effort to strengthen our users’ security, we recently announced that we would make all Yahoo Mail connections encrypted with HTTPS by January 8, 2014.

This means that we’re introducing HTTPS for our Yahoo Mail APIs. All developers using our Yahoo Mail APIs will need to make these update to their API settings by December 18, 2013:

Protocol: HTTPS
Port: 443

The domain name ( will remain the same.

All non-HTTP API access to Yahoo Mail will be shutdown on December 18, 2013. If you don’t update to HTTPS, your users will not be able to access their Yahoo Accounts via your service.

Thank you for helping Yahoo Mail make the shift to HTTPS.

UPDATE: We have extended this deadline. All non-HTTP API access to Yahoo Mail will now be shut down on 24th March, 2014.
