Little known @Twitter and @TwitterAPI tips and tricks

Be sure to comeback as new tips and tricks get added. If you know of anything I missed be sure to let me know.

Static URL for profile images based on screen_name:

https://api.twitter.com/1/users/profile_image/abraham

* This performs a http redirect to the actual profile image URL. Currently https redirects to http. You can also add "?size={mini | bigger | normal}" to get specific sizes.

Redirect to profile based on user_id:

https://twitter.com/account/redirect_by_id?id=9436992

In_reply_to_status_id mentions:

https://api.twitter.com/1/statuses/update.json?status=reply+to+@abraham&in_reply_to_status_id=12410413197

* In the web interface new mentions are only replies if they start with @screen_name. By pushing @screen_name further along in the string your followers who do not follow @screen_name will still see the status.

Profile image sizes:

http://a3.twimg.com/profile_images/54160223/chart-black-small.png

* By default you get the original image size you can add _mini, _normal, and _bigger just before the image extension to change the size returned.
