Using StreamingClient

To use StreamingClient, an instance of it needs to be initialized with a Twitter API Bearer Token:

import tweepy

streaming_client = tweepy.StreamingClient("Bearer Token here")

Then, StreamingClient.sample() can be used to connect to and run a sampling stream:


Or StreamingClient.add_rules() can be used to add rules before using StreamingClient.filter() to connect to and run a filtered stream:


StreamingClient.get_rules() can be used to retrieve existing rules and StreamingClient.delete_rules() can be used to delete rules.

To learn how build rules, refer to the Twitter API Building rules for filtered stream documentation.

Data received from the stream is passed to StreamingClient.on_data(). This method handles sending the data to other methods. Tweets recieved are sent to StreamingClient.on_tweet(), includes data are sent to StreamingClient.on_includes(), errors are sent to StreamingClient.on_errors(), and matching rules are sent to StreamingClient.on_matching_rules(). A StreamResponse instance containing all four fields is sent to StreamingClient.on_response(). By default, only StreamingClient.on_response() logs the data received, at the DEBUG logging level.

To customize the processing of the stream data, StreamingClient needs to be subclassed. For example, to print the IDs of every Tweet received:

class IDPrinter(tweepy.StreamingClient):

    def on_tweet(self, tweet):

printer = IDPrinter("Bearer Token here")


StreamingClient.filter() and StreamingClient.sample() have a threaded parameter. When set to True, the stream will run in a separate thread, which is returned by the call to the method. For example:

thread = streaming_client.sample(threaded=True)

Handling Errors

StreamingClient has multiple methods to handle errors during streaming.

StreamingClient.on_closed() is called when the stream is closed by Twitter.

StreamingClient.on_connection_error() is called when the stream encounters a connection error.

StreamingClient.on_request_error() is called when an error is encountered while trying to connect to the stream.

When these errors are encountered and max_retries, which defaults to infinite, hasn’t been exceeded yet, the StreamingClient instance will attempt to reconnect the stream after an appropriate amount of time. By default, all three of these methods log an error. To customize that handling, they can be overridden in a subclass:

class ConnectionTester(tweepy.StreamingClient):

    def on_connection_error(self):

StreamingClient.on_request_error() is also passed the HTTP status code that was encountered. The HTTP status codes reference for the Twitter API can be found at

StreamingClient.on_exception() is called when an unhandled exception occurs. This is fatal to the stream, and by default, an exception is logged.
