Applications are no longer being accepted. Site streams will eventually be replaced by the Account Activity API.
Site Streams allows services, such as web sites or mobile push services, to receive real-time updates for a large number of users. Events may be streamed for any user who has granted OAuth access to your application. Desktop applications or applications with few users should use user streams.
Site Streams deliver the same types of messages streamed to User Streams, with an additional wrapper indicating the user the message is targeted to. See streaming message types for information.
Site Streams may deliver both public and private data in a single stream. Applications must be meticulous about what data they display:
- Data should be restricted by default, and only anonymously accessible if you can verify it to be public. This is essential to prevent new private message types or similar changes from being shared by default.
- Private data must only be displayed to users who present the corresponding authentication token.
- Do not expose or otherwise draw attention to status deletions or unfollows to users, other than to update displays.
These rules are covered in the Developer Policy. Violations will result in immediate suspension from Site Streams and possibly all Twitter APIs.
Site Streams only accepts OAuth-signed requests from the owner of the application which is connecting. Use the “Your Access Token” feature of your application settings page to quickly obtain a valid access token.
When connecting, specify a list of users to include in the stream using the follow parameter. Note that you will only receive messages for users who have approved (and not revoked) OAuth access to your application at some point in the past.
Minimize the number of reconnections you make by modifying open streams with control streams.
Streams with large numbers of users may consume significant (> 1 Mbit/sec) bandwidth. Follow best practices for processing streaming data and keep in mind that slow reading applications will automatically be disconnected.
The following limitations must be respected during the beta period. These limits will most likely change when Site Streams comes out of beta:
- Limit the follow count to 100 users per stream while connecting. Use Control Streams to add up to 1,000 users per connection. See Control Streams for Site Streams.
- Open no more than 25 new connections per second and exponentially back-off on errors.
- If you intend to open more than roughly a thousand connections, you should coordinate your testing and launch with the Twitter Platform team.
Read the user streams documentation. Site Streams are similar to User Streams—other than multiplexing many User Streams over a connection, almost all of the guidelines outlined also apply to Site Streams.
Site Streams does not support any of the filter parameters such as
keywords, so if your application requires these capabilities, Site Streams may not be the right fit. Site Streams access does not provide a greater percentage of the firehose than the self-serve options available today.
As new users authorize your application, you will need to add them to your streams. The best way to do this is to use control streams.
If you are unable to use control streams, open a series of small streams for recently added users. Once you have a sufficient number of small streams open, create a larger stream that contains all recent users and disconnect the small streams.
Do not attempt to open all connections at once. Implement a cap on the number of connections you make per second. The number of connections your application establishes (even across multiple hosts) must be less than 25.
