Use the Python SDK

Initialization

You can initialize the Optimizely instance in three ways: with a datafile, by providing an sdk_key, or by providing an implementation of BaseConfigManager. Each method is described below.

  1. Initialize Optimizely with a datafile. This datafile will be used as the source of ProjectConfig throughout the life of Optimizely instance:

    optimizely.Optimizely(
  datafile
)

  2. Initialize Optimizely by providing an 'sdk_key'. This will initialize a PollingConfigManager that makes an HTTP GET request to the URL (formed using your provided sdk key and the default datafile CDN URL template) to asynchronously download the project datafile at regular intervals and update ProjectConfig when a new datafile is received. A hard-coded datafile can also be provided along with the sdk_key that will be used initially before any update:

    optimizely.Optimizely(
  sdk_key='put_your_sdk_key_here'
)

    If providing a datafile, the initialization will look like:

    optimizely.Optimizely(
  datafile=datafile,
  sdk_key='put_your_sdk_key_here'
)

  3. Initialize Optimizely by providing a ConfigManager that implements BaseConfigManager. You may use our PollingConfigManager or AuthDatafilePollingConfigManager as needed:

    optimizely.Optimizely(
  config_manager=custom_config_manager
)

PollingConfigManager

The PollingConfigManager asynchronously polls for datafiles from a specified URL at regular intervals by making HTTP requests.

polling_config_manager = PollingConfigManager(
    sdk_key=None,
    datafile=None,
    update_interval=None,
    url=None,
    url_template=None,
    logger=None,
    error_handler=None,
    notification_center=None,
    skip_json_validation=False
)

Note: You must provide either the sdk_key or URL. If you provide both, the URL takes precedence.

sdk_key The sdk_key is used to compose the outbound HTTP request to the default datafile location on the Optimizely CDN.

datafile You can provide an initial datafile to bootstrap the ProjectConfigManager so that it can be used immediately. The initial datafile also serves as a fallback datafile if HTTP connection cannot be established. The initial datafile will be discarded after the first successful datafile poll.

update_interval The update_interval is used to specify a fixed delay in seconds between consecutive HTTP requests for the datafile.

url The target URL from which to request the datafile.

url_template A string with placeholder {sdk_key} can be provided so that this template along with the provided sdk key is used to form the target URL.

You may also provide your own logger, error_handler, or notification_center.

AuthDatafilePollingConfigManager

The AuthDatafilePollingConfigManager implements PollingConfigManager and asynchronously polls for authenticated datafiles from a specified URL at regular intervals by making HTTP requests.

auth_datafile_polling_config_manager = AuthDatafilePollingConfigManager(
    datafile_access_token,
    *args,
    **kwargs
)

Note: To use AuthDatafilePollingConfigManager, you must create a secure environment for your project and generate an access token for your datafile.

datafile_access_token The datafile_access_token is attached to the outbound HTTP request header to authorize the request and fetch the datafile.

Advanced configuration

The following properties can be set to override the default configurations for PollingConfigManager and AuthDatafilePollingConfigManager.

Property Name Default Value Description
sdk_key None Optimizely project SDK key
datafile None Initial datafile, typically sourced from a local cached source
update_interval 5 minutes Fixed delay between fetches for the datafile
url None Custom URL location from which to fetch the datafile
url_template PollingConfigManager:
https://cdn.optimizely.com/datafiles/{sdk_key}.json
AuthDatafilePollingConfigManager:
https://config.optimizely.com/datafiles/auth/{sdk_key}.json		 Parameterized datafile URL by SDK key

A notification signal will be triggered whenever a new datafile is fetched and Project Config is updated. To subscribe to these notifications, use:

notification_center.add_notification_listener(NotificationTypes.OPTIMIZELY_CONFIG_UPDATE, update_callback)

For Further details see the Optimizely Feature Experimentation documentation to learn how to set up your first Python project and use the SDK.

SDK Development

Building the SDK

Build and install the SDK with pip, using the following command:

pip install -e .

Unit Tests

Running all tests

To get test dependencies installed, use a modified version of the install command:

pip install -e '.[test]'

You can run all unit tests with:

pytest

Running all tests in a file

To run all tests under a particular test file you can use the following command:

pytest tests.<file_name_without_extension>

For example, to run all tests under test_event_builder, the command would be:

pytest tests/test_event_builder.py

Running all tests under a class

To run all tests under a particular class of tests you can use the following command:

pytest tests/<file_name_with_extension>::ClassName

For example, to run all tests under test_event_builder.EventTest, the command would be:

pytest tests/test_event_builder.py::EventTest

Running a single test

To run a single test you can use the following command:

pytest tests/<file_name_with_extension>::ClassName::test_name

For example, to run test_event_builder.EventTest.test_init, the command would be:

pytest tests/test_event_builder.py::EventTest::test_init

Optimizely Python SDK Changelog

5.0.0

January 18th, 2024

New Features

The 5.0.0 release introduces a new primary feature, Advanced Audience Targeting enabled through integration with Optimizely Data Platform (ODP) (#395, #398, #402, #403, #405).

You can use ODP, a high-performance Customer Data Platform (CDP), to easily create complex real-time segments (RTS) using first-party and 50+ third-party data sources out of the box. You can create custom schemas that support the user attributes important for your business, and stitch together user behavior done on different devices to better understand and target your customers for personalized user experiences. ODP can be used as a single source of truth for these segments in any Optimizely or 3rd party tool.

With ODP accounts integrated into Optimizely projects, you can build audiences using segments pre-defined in ODP. The SDK will fetch the segments for given users and make decisions using the segments. For access to ODP audience targeting in your Feature Experimentation account, please contact your Optimizely Customer Success Manager.

This version includes the following changes:

  • New API added to OptimizelyUserContext:

    • fetchQualifiedSegments(): this API will retrieve user segments from the ODP server. The fetched segments will be used for audience evaluation. The fetched data will be stored in the local cache to avoid repeated network delays.
    • When an OptimizelyUserContext is created, the SDK will automatically send an identify request to the ODP server to facilitate observing user activities.

  • New APIs added to OptimizelyClient:

    • sendOdpEvent(): customers can build/send arbitrary ODP events that will bind user identifiers and data to user profiles in ODP.

For details, refer to our documentation pages:

Logging

  • Add warning to polling intervals below 30 seconds (#428)
  • Add warning to duplicate experiment keys (#430)

Enhancements

  • Added py.typed to enable external usage of mypy type annotations.

Breaking Changes

  • Updated minimum supported Python version from 3.7 -> 3.8
  • ODPManager in the SDK is enabled by default. Unless an ODP account is integrated into the Optimizely projects, most ODPManager functions will be ignored. If needed, ODPManager can be disabled when OptimizelyClient is instantiated.
  • BaseConfigManager abstract class now requires a get_sdk_key method. (#413)
  • PollingConfigManager requires either the sdk_key parameter or datafile containing an sdkKey. (#413)
  • Asynchronous BatchEventProcessor is now the default event processor. (#378)

Deprecated:

  • Activate notification listener is deprecated as of this release. Recommendation is to use the new Decision notification listener. Activate notification listener will be removed in the next major release.

3.0.0

March 1st, 2019

The 3.0 release improves event tracking and supports additional audience targeting functionality.

New Features:

  • Event tracking:
    • The track method now dispatches its conversion event unconditionally, without first determining whether the user is targeted by a known experiment that uses the event. This may increase outbound network traffic.
    • In Optimizely results, conversion events sent by 3.0 SDKs don't explicitly name the experiments and variations that are currently targeted to the user. Instead, conversions are automatically attributed to variations that the user has previously seen, as long as those variations were served via 3.0 SDKs or by other clients capable of automatic attribution, and as long as our backend actually received the impression events for those variations.
    • Altogether, this allows you to track conversion events and attribute them to variations even when you don't know all of a user's attribute values, and even if the user's attribute values or the experiment's configuration have changed such that the user is no longer affected by the experiment. As a result, you may observe an increase in the conversion rate for previously-instrumented events. If that is undesirable, you can reset the results of previously-running experiments after upgrading to the 3.0 SDK. - This will also allow you to attribute events to variations from other Optimizely projects in your account, even though those experiments don't appear in the same datafile.
    • Note that for results segmentation in Optimizely results, the user attribute values from one event are automatically applied to all other events in the same session, as long as the events in question were actually received by our backend. This behavior was already in place and is not affected by the 3.0 release.
  • Support for all types of attribute values, not just strings.
    • All values are passed through to notification listeners.
    • Strings, booleans, and valid numbers are passed to the event dispatcher and can be used for Optimizely results segmentation. A valid number is a finite float or numbers.Integral in the inclusive range [-2 ^ 53, 2 ^ 53].
    • Strings, booleans, and valid numbers are relevant for audience conditions.
  • Support for additional matchers in audience conditions:
    • An exists matcher that passes if the user has a non-null value for the targeted user attribute and fails otherwise.
    • A substring matcher that resolves if the user has a string value for the targeted attribute.
      • gt (greater than) and lt (less than) matchers that resolve if the user has a valid number value for the targeted attribute. A valid number is a finite float or numbers.Integral in the inclusive range [-2 ^ 53, 2 ^ 53].
      • The original (exact) matcher can now be used to target booleans and valid numbers, not just strings.
  • Support for A/B tests, feature tests, and feature rollouts whose audiences are combined using "and" and "not" operators, not just the "or" operator.
  • Datafile-version compatibility check: The SDK will remain uninitialized (i.e., will gracefully fail to activate experiments and features) if given a datafile version greater than 4.
  • Updated Pull Request template and commit message guidelines.

Breaking Changes:

  • Conversion events sent by 3.0 SDKs don't explicitly name the experiments and variations that are currently targeted to the user, so these events are unattributed in raw events data export. You must use the new results export to determine the variations to which events have been attributed.
  • Previously, notification listeners were only given string-valued user attributes because only strings could be passed into various method calls. That is no longer the case. You may pass non-string attribute values, and if you do, you must update your notification listeners to be able to receive whatever values you pass in.

Bug Fixes:

  • Experiments and features can no longer activate when a negatively targeted attribute has a missing, null, or malformed value.
    • Audience conditions (except for the new exists matcher) no longer resolve to false when they fail to find an legitimate value for the targeted user attribute. The result remains null (unknown). Therefore, an audience that negates such a condition (using the "not" operator) can no longer resolve to true unless there is an unrelated branch in the condition tree that itself resolves to true.
  • Updated the default event dispatcher to log an error if the request resolves to HTTP 4xx or 5xx. (#140)
  • All methods now validate that user IDs are strings and that experiment keys, feature keys, feature variable keys, and event keys are non-empty strings.

2.1.1

August 21st, 2018

  • Fix: record conversions for all experiments using an event when using track(#136).

2.1.0

2.0.0

April 12th, 2018

This major release introduces APIs for Feature Management. It also introduces some breaking changes listed below.

New Features

  • Introduced the is_feature_enabled API to determine whether to show a feature to a user or not.
    is_enabled = optimizel_client.is_feature_enabled('my_feature_key', 'my_user', user_attributes)
  • All enabled features for the user can be retrieved by calling:
    enabled_features = optimizely_client.get_enabled_features('my_user', user_attributes)
  • Introduced Feature Variables to configure or parameterize a feature. There are four variable types: String, Integer, Double, Boolean.
    string_variable = optimizely_client.get_feature_variable_string('my_feature_key', 'string_variable_key', 'my_user')
    integer_variable = optimizely_client.get_feature_variable_integer('my_feature_key', 'integer_variable_key', 'my_user')
    double_variable = optimizely_client.get_feature_variable_double('my_feature_key', 'double_variable_key', 'my_user')
    boolean_variable = optimizely_client.get_feature_variable_boolean('my_feature_key', 'boolean_variable_key', 'my_user')

Breaking changes

  • The track API with revenue value as a stand-alone parameter has been removed. The revenue value should be passed in as an entry in the event tags dict. The key for the revenue tag is revenue and the passed in value will be treated by Optimizely as the value for computing results.
    event_tags = {
      'revenue': 1200
    }

    optimizely_client.track('event_key', 'my_user', user_attributes, event_tags)
