pip install stream-python

Usage

# Instantiate a new client
import stream
client = stream.connect('YOUR_API_KEY', 'API_KEY_SECRET')
# Find your API keys here https://getstream.io/dashboard/

# Instantiate a feed object
user_feed_1 = client.feed('user', '1')

# Get activities from 5 to 10 (slow pagination)
result = user_feed_1.get(limit=5, offset=5)
# (Recommended & faster) Filter on an id less than the given UUID
result = user_feed_1.get(limit=5, id_lt="e561de8f-00f1-11e4-b400-0cc47a024be0")

# Create a new activity
activity_data = {'actor': 1, 'verb': 'tweet', 'object': 1, 'foreign_id': 'tweet:1'}
activity_response = user_feed_1.add_activity(activity_data)
# Create a bit more complex activity
activity_data = {'actor': 1, 'verb': 'run', 'object': 1, 'foreign_id': 'run:1', 
	'course': {'name': 'Golden Gate park', 'distance': 10},
	'participants': ['Thierry', 'Tommaso'],
	'started_at': datetime.datetime.now()
}
user_feed_1.add_activity(activity_data)

# Remove an activity by its id
user_feed_1.remove_activity("e561de8f-00f1-11e4-b400-0cc47a024be0")
# or by foreign id
user_feed_1.remove_activity(foreign_id='tweet:1')

# Follow another feed
user_feed_1.follow('flat', '42')

# Stop following another feed
user_feed_1.unfollow('flat', '42')

# List followers/following
following = user_feed_1.following(offset=0, limit=2)
followers = user_feed_1.followers(offset=0, limit=10)

# Creates many follow relationships in one request
follows = [
    {'source': 'flat:1', 'target': 'user:1'},
    {'source': 'flat:1', 'target': 'user:2'},
    {'source': 'flat:1', 'target': 'user:3'}
]
client.follow_many(follows)

# Batch adding activities
activities = [
	{'actor': 1, 'verb': 'tweet', 'object': 1},
	{'actor': 2, 'verb': 'watch', 'object': 3}
]
user_feed_1.add_activities(activities)

# Add an activity and push it to other feeds too using the `to` field
activity = {
    "actor":"1",
    "verb":"like",
    "object":"3",
    "to":["user:44", "user:45"]
}
user_feed_1.add_activity(activity)

# Generating tokens for client side usage (JS client)
token = user_feed_1.token
# Javascript client side feed initialization
# user1 = client.feed('user', '1', '{{ token }}');

# Generate a read-only token for client side usage (JS client)
readonly_token = user_feed_1.get_readonly_token()
# Javascript client side feed initialization
# user1 = client.feed('user', '1', '{{ readonly_token }}');
