Keen IO Official Python Client Library

Build Status

This is the official Python Client for the Keen IO API. The Keen IO API lets developers build analytics features directly into their apps.

This is still under active development. Stay tuned for improvements!


Use pip to install!

pip install keen

This client is known to work on Python 2.6, 2.7, 3.2, and 3.3


To use this client with the Keen IO API, you have to configure your Keen IO Project ID and its access keys (if you need an account, sign up here - it's free).

Setting a write key is required for publishing events. Setting a read key is required for running queries. The recommended way to set this configuration information is via the environment. The keys you can set are KEEN_PROJECT_ID, KEEN_WRITE_KEY, and KEEN_READ_KEY.

If you don't want to use environment variables for some reason, you can directly set values as follows:

    keen.project_id = "xxxx"
    keen.write_key = "yyyy"
    keen.read_key = "zzzz"

You can also configure unique client instances as follows:

    from keen.client import KeenClient

    client = KeenClient(
Send Events to Keen IO

Once you've set KEEN_PROJECT_ID and KEEN_WRITE_KEY, sending events is simple:

    keen.add_event("sign_ups", {
        "username": "lloyd",
        "referred_by": "harry"
Send Batch Events to Keen IO

You can upload Events in a batch, like so:

    # uploads 4 events total - 2 to the "sign_ups" collection and 2 to the "purchases" collection
        "sign_ups": [
            { "username": "nameuser1" },
            { "username": "nameuser2" } 
        "purchases": [
            { "price": 5 },
            { "price": 6 }

That's it! After running your code, check your Keen IO Project to see the event/events has been added.

Do analysis with Keen IO

Here are some examples of querying. Let's assume you've added some events to the "purchases" collection.

    keen.count("purchases") # => 100
    keen.sum("purchases", target_property="price") # => 10000
    keen.minimum("purchases", target_property="price") # => 20
    keen.maximum("purchases", target_property="price") # => 100
    keen.average("purchases", target_property="price") # => 49.2

    keen.sum("purchases", target_property="price", group_by="") # => [{ "": 123, "result": 240 }, { ... }]

    keen.count_unique("purchases", target_property="") # => 3
    keen.select_unique("purchases", target_property="") # => ["", ""]

    keen.extraction("purchases", timeframe="today") # => [{ "price" => 20, ... }, { ... }]

    keen.multi_analysis("purchases", analyses={"total":{"analysis_type":"sum", "target_property":"price"}, "average":{"analysis_type":"average", "target_property":"price"}) # => {"total":10329.03, "average":933.93}

    step1 = {
        "event_collection": "signup",
        "actor_property": ""
    step2 = {
        "event_collection": "purchase",
        "actor_property": ""
    keen.funnel([step1, step2], timeframe="today") # => [2039, 201]

Advanced Usage

See below for more options.

Send to Keen IO with a Timeout

By default, POST requests will timeout after 305 seconds. If you want to manually override this, you can create a KeenClient with the "post_timeout" parameter. This client will fail POSTs if no bytes have been returned by the server in the specified time. For example:

    from keen.client import KeenClient

    client = KeenClient(
    delete_key="qqqq", # Only if event_delete is required


This will cause both add_event() and add_events() to timeout after 100 seconds. If this timeout limit is hit, a requests.Timeout will be raised. Due to a bug in the requests library, you might also see an SSLError (

Create Scoped Keys

The Python client enables you to create Scoped Keys easily. For example:

    from keen.client import KeenClient
    from keen import scoped_keys

    api_key = KEEN_MASTER_KEY

    write_key = scoped_keys.encrypt(api_key, {"allowed_operations": ["write"]})
    read_key = scoped_keys.encrypt(api_key, {"allowed_operations": ["read"]})

write_key and read_key now contain scoped keys based on your master API key.


  • Add event_delete

  • Fixed sys.version_info issue with Python 2.6
  • Added interval to multi_analysis.
  • Added stacktrace_id and unique_id to Keen API errors.
  • Added add_events method to keen/ so it can be used at a module level.
  • Added method to generate image beacon URLs.
  • Added support for publishing events in batches
  • Added support for configuring client automatically from environment
  • Added methods on keen module directly
