  title: Braze User Data API
  description: 'The Braze and Radar integration allows you to access sophisticated location-based campaign triggers and user profile enrichment with rich, first-party location data. When Radar geofence or trip tracking events are generated, custom events and user attributes are sent to Braze in real-time. These events and attributes can then be used to trigger location-based campaigns, power last-mile pickup and delivery operations, monitor fleet and shipping logistics, or build user segments based on location patterns.

  description: 'The User API allows you to track information on your users by logging data about your users that comes from outside your mobile app. You can also use this API to delete users for testing or other purposes.


    All API endpoints have a data payload limit of 4MB. Attempts to post more data than 4MB will fail with an HTTP 413 Request Entity Too Large.


    The examples below contain the URL https://rest.iad-01.braze.com, but some customers will need to use a different endpoint URL, for example if you are hosted in Brazes EU data center or have a dedicated Braze installation. Your Success Manager will inform you if you should use a different endpoint URL.

      summary: Track Users
      description: "> Use this endpoint to record custom events, purchases, and update user profile attributes. \n  \n\nTo use this endpoint, youll need to generate an API key with the `users.track` permission.\n\n**Note:** Braze processes the data passed via API at face value and customers should only pass deltas (changing data) to minimize unnecessary data point consumption. To read more, refer to [Data points](https://www.braze.com/docs/user_guide/onboarding_with_braze/data_points#data-points).\n\nCustomers using the API for server-to-server calls may need to allowlist `rest.iad-01.braze.com` if theyre behind a firewall.\n\n### Rate limit\n\nWe apply a base speed limit of 50,000 requests per minute to this endpoint for all customers. Each request to the `/users/track` endpoint can contain up to 75 events, 75 attribute updates, and 75 purchases. Each component (event, attribute, and purchase arrays), can update up to 75 users each for a max of 225 individual data points. Each update can also belong to the same user for a max of 225 updates to a single user in a request.\n\nSee our page on [API rate limits](https://www.braze.com/docs/api/api_limits/) for details, and reach out to your customer success manager if you need your limit increased.\n\n### Request parameters\n\nFor each of the request components listed in the following table, one of `external_id`, `user_alias`, or `braze_id` is required.\n\n| Parameter | Required | Data Type | Description |\n| --- | --- | --- | --- |\n| `attributes` | Optional | Array of attributes objects | See [user attributes object](https://www.braze.com/docs/api/objects_filters/user_attributes_object/) |\n| `events` | Optional | Array of event objects | See [events object](https://www.braze.com/docs/api/objects_filters/event_object/) |\n| `purchases` | Optional | Array of purchase objects | See [purchases object](https://www.braze.com/docs/api/objects_filters/purchase_object/) |\n\n## User track responses\n\nUpon using any of the aforementioned API requests you should receive one of the following three general responses:\n\n#### Successful message\n\nSuccessful messages will be met with the following response:\n\n``` json\n{\n  \"message\" : \"success\",\n  \"attributes_processed\" : (optional, integer), if attributes are included in the request, this will return an integer of the number of external_ids with attributes that were queued to be processed,\n  \"events_processed\" : (optional, integer), if events are included in the request, this will return an integer of the number of events that were queued to be processed,\n  \"purchases_processed\" : (optional, integer), if purchases are included in the request, this will return an integer of the number of purchases that were queued to be processed,\n}\n\n```\n\n#### Successful message with non-fatal errors\n\nIf your message is successful but has non-fatal errors such as one invalid event object out of a long list of events, then you will receive the following response:\n\n``` json\n{\n  \"message\" : \"success\",\n  \"errors\" : [\n    {\n    }\n  ]\n}\n\n```\n\n#### Message with fatal errors\n\nIn the case of a success, any data that was not affected by an error in the `errors` array will still be processed. If your message has a fatal error you will receive the following response:\n\n``` json\n{\n  \"message\" : ,\n  \"errors\" : [\n    {\n    }\n  ]\n}\n\n```\n\n### Fatal error response codes\n\nFor status codes and associated error messages that will be returned if your request encounters a fatal error, reference [Fatal errors & responses](https://www.braze.com/api/errors/#fatal-errors).\n\nIf you receive the error provided external_id is blacklisted and disallowed, your request may have included a dummy user. For more information, refer to [Spam blocking](https://www.braze.com/docs/user_guide/data_and_analytics/user_data_collection/user_archival/#spam-blocking).\n\n### Creating an alias-only user profile\n\nKeep the following nuances in mind when using the `/users/track` endpoint:\n\nYou can use the `/users/track` endpoint to create a new alias-only user by setting the `_update_existing_only` key with a value of `false` in the body of the request. If this value is omitted, the alias-only user profile will not be created. Using an alias-only user guarantees that one profile with that alias will exist. This is especially helpful when building a new integration as it prevents the creation of duplicate user profiles.\n\n### Importing legacy user data\n\nYou may submit data through the Braze API for a user who has not yet used your mobile app in order to generate a user profile. If the user subsequently uses the application all information following their identification via the SDK will be merged with the existing user profile you created via the API call. Any user behavior that is recorded anonymously by the SDK prior to identification will be lost upon merging with the existing API-generated user profile.\n\nThe segmentation tool will include these users regardless of whether they have engaged with the app. If you want to exclude users uploaded via the User API who have not yet engaged with the app, simply add the filter: `Session Count > 0`.\n\n### Making bulk updates\n\nIf you have a use case where you need to make batch updates to the `users/track` endpoint, we recommend adding the bulk update header so that Braze can properly identify, observe, and route your request.\n\nRefer to the following sample request with the `X-Braze-Bulk` header:\n\n``` json\ncurl --location --request POST 'https://rest.iad-01.braze.com/users/track' \\\n--header 'Content-Type: application/json' \\\n--header 'X-Braze-Bulk: true' \\\n--header 'Authorization: Bearer YOUR-API-KEY-HERE' \\\n--data-raw '{ \"attributes\": [ ], \"events\": [ ], \"purchases\": [ ] }'\n\n```\n\nWarning: When the `X-Braze-Bulk` header is present with any value, Braze will consider the request a bulk request. Set the value to `true`. Currently, setting the value to `false` does not disable the headerit will still be treated as if it were true.\n\n#### Use cases\n\nConsider the following use cases where you may use the bulk update header:\n\n- A daily job where multiple users custom attributes are updated via the `/users/track` endpoint.\n- An ad-hoc user data backfill script which updates user information via the `/users/track` endpoint."

      summary: Identify Users
      description: "> Use this endpoint to identify an unidentified (alias-only) user. \n  \n\nTo use this endpoint, youll need to generate an API key with the `users.identify` permission.\n\nCalling `/users/identify` combines the alias-only profile with the identified profile and removes the alias-only profile.\n\nIdentifying a user requires an `external_id` to be included in the `aliases_to_identify` object. If there is no user with that `external_id`, the `external_id` will simply be added to the aliased user's record, and the user will be considered identified. You can add up to 50 user aliases per request.\n\nSubsequently, you can associate multiple additional user aliases with a single `external_id`.\n\n- When these subsequent associations are made with the `merge_behavior` field set to `none`, only the push tokens and message history associated with the user alias are retained; any attributes, events, or purchases will be \"orphaned\" and not available on the identified user. One workaround is to export the aliased user's data before identification using the [`/users/export/ids` endpoint](https://www.braze.com/docs/api/endpoints/export/user_data/post_users_identifier/), then re-associate the attributes, events, and purchases with the identified user.\n- When associations are made with the `merge_behavior` field set to `merge`, this endpoint will merge [specific fields](#merge) found on the anonymous user to the identified user.\n    \n\n> Note: To prevent unexpected loss of data when identifying users, we highly recommend that you first refer to [data collection best practices](https://www.braze.com/docs/user_guide/data_and_analytics/user_data_collection/best_practices/#capturing-user-data-when-alias-only-user-info-is-already-present) to learn about capturing user data when alias-only user info is already present. \n  \n\n### Rate limit\n\nFor customers who onboarded with Braze on or after September 16, 2021, we apply a shared rate limit of 20,000 requests per minute to this endpoint. This rate limit is shared with the `/users/delete` and `/users/alias/new` endpoints, as documented in [API rate limits](https://www.braze.com/docs/api/api_limits/).\n\n### Parameters\n\n| Parameter | Required | Data Type | Description |\n| --- | --- | --- | --- |\n| `aliases_to_identify` | Required | Array of aliases to identify object | See [alias to identify object](https://www.braze.com/docs/api/objects_filters/aliases_to_identify/) and [user alias object](https://www.braze.com/docs/api/objects_filters/user_alias_object/). |\n| `merge_behavior` | Optional | String | One of `none` or `merge` is expected. |\n\n#### Merge_behavior field\n\nSetting the `merge_behavior` field to `merge` sets the endpoint to merge any of the following fields found **exclusively** on the anonymous user to the identified user.\n\n- First name\n- Last name\n- Email\n- Gender\n- Date of birth\n- Phone number\n- Time zone\n- Home city\n- Country\n- Language\n- Session count (the sum of sessions from both profiles)\n- Date of first session (Braze will pick the earlier date of the two dates)\n- Date of last session (Braze will pick the later date of the two dates)\n- Custom attributes\n- Custom event and purchase event data (excluding event properties)\n- Custom event and purchase event properties for \"X times in Y days\" segmentation (where X<=50 and Y<=30)\n- Segmentable custom events summary\n    - Event count (the sum from both profiles)\n    - Event first occurred (Braze will pick the earlier date of the two dates)\n    - Event last occurred (Braze will pick the later date of the two dates)\n- In-app purchase total in cents (the sum from both profiles)\n- Total number of purchases (the sum from both profiles)\n- Date of first purchase (Braze will pick the earlier date of the two dates)\n- Date of last purchase (Braze will pick the later date of the two dates)\n- App summaries\n- Last_X_at fields (Braze will update the fields if the orphaned profile fields are more recent)\n- Campaign summaries (Braze will pick the most recent date fields)\n- Workflow summaries (Braze will pick the most recent date fields)\n- Message and message engagement history\n    \n\nAny of the following fields found on the anonymous user to the identified user:\n\n- Custom event and purchase event count and first date and last date timestamps\n    - These merged fields will update \"for X events in Y days\" filters. For purchase events, these filters include \"number of purchases in Y days\" and \"money spent in last Y days\".\n\nSession data will only be merged if the app exists on both user profiles. For example, if our target user doesn't have an app summary for \"ABCApp\" but our original user does, the target user will have the \"ABCApp\" app summary on their profile after the merge.\n\nSetting the field to `none` will not merge any user data to the identified user profile.\n\n### Aliases to Identify object specification\n\n``` json\n{\n  \"external_id\" : (required, string) see External User ID below,\n  // external_ids for users that do not exist will return a non-fatal error. \n  // See Server Responses for details.\n  \"user_alias\" : {\n    \"alias_name\" : (required, string),\n    \"alias_label\" : (required, string)\n  }\n}\n\n```"
