Taxonomy API

The Taxonomy API grants Enterprise users the ability to programmatically plan their event schema in the Taxonomy tab.

The Taxonomy API lets you create, get, update, and delete categories, event types, event properties, and user properties.

Authentication

This API uses basic authentication, using the API key and secret key for your project. Pass base64-encoded credentials in the request header like {api-key}:{secret-key}. api-key replaces username, and secret-key replaces the password.

Your authorization header should look something like this:

--header 'Authorization: Basic YWhhbWwsdG9uQGFwaWdlZS5jb206bClwYXNzdzByZAo'`

For more information, see Find your API Credentials

Endpoints

Region Endpoint
Standard server https://amplitude.com/api/2/
EU residency server https://analytics.eu.amplitude.com/api/2/

Considerations

  • You may have to URL encode special characters in the names of event types, event properties, and user properties.
    For example, encode Play Song as Play%20Song. Use the W3Schools encoding reference.
  • In responses, custom user properties have a gp: prefix. For example, gp:my_custom_property.
  • You must plan events or properties in the schema before you can delete them via this API.

Limits

For each endpoint, there is a concurrent and a rate limit. This limit restricts the number of requests you can run at the same time, while the rate limit restricts the total number of queries you can run per hour.

Limits are per project, and exceeding any of these limits returns a 429 error.

The endpoints use a cost per query model. Here are the max costs per API Key:

  • Concurrent Cost Limit: You can run queries that collectively add up to 4 cost at the same time.
  • Period Cost Limit: You can run up to 7200 cost per hour.

Cost structure of each endpoint:

  • GET: 1 cost
  • PUT: 2 cost
  • POST: 2 cost
  • DELETE: 2 cost

Event category

Event categories are a way to organize your event types into broad groups.

Example

You want to track how users register for your app, checkout, and how they interact with the onboarding experience. You can bucket your events using these event categories:

  • Registration
  • Checkout
  • Onboarding

Create event category

Create an event category in your project.

Name
Description
event_property Required. String. Name of the event property.
event_type Optional. String. Name of the event type to which the event property belongs to. If the event property already exists on this event type, Amplitude returns a 409 Conflict error. If the event property already exists but not on this event type, Amplitiude creates an override for this property. If the event property doesn't exist anywhere, Amplitude doesn't create an override for this property.
description Optional. String. The event property's description.
type Optional. String. The event property's data type. Acceptable values are string, number, boolean, enum, and any

Path parameters

Name
Description
event-property Required. Name of the event property.

Body parameters

Name
Description
event_type Optional. Name of the event type to which the event properties belong to. If the event property already exists on this event type, Amplitude returns a 409 Conflict error. If the event property already exists but not on this event type, Amplitude creates an override for this property. If the event property doesn't exist anywhere, Amplitude doesn't create an override for this property.
overrideScope Optional. Determines how we should act on this event property. Only applicable if event_type is present. If overrideScope is not present, Amplitude updates property override on the event if it exists on the event, or the shared property if no override exists on the event. With overrideScope: "override", Amplitude creates an override if none exists on the event, then updates that overridden property, or it updates the existing override if one already exists. With overrideScope: "shared", Amplitude removes the property override on the event if one exists on the event, then updates the shared property, or updates the shared property if no property override exists.
description Optional. String. The event property's description.
new_event_property_value Optional. String. The new name of the event property.
type Optional. String. The event property's data type. Acceptable values are string, number, boolean, enum, and any
regex Optional. String. Regular expression, custom regex used for pattern matching or more complex values. For example, property zip code must have pattern [0-9]{5}
enum_values Optional. String. List of allowed values.
is_array_type Optional. Boolean. Specifies whether the property value is an array.
is_required Optional. Boolean. Marks the property as required.
classifications Optional. String. Only available if Data Access Controls is enabled at the account level. List of classifications applicable to this event property. Valid classifications are PII, SENSITIVE and REVENUE. You can only apply classifications on shared properties, and trying to set classifications on an overridden property results in an error. With overrideScope: "override", Amplitude returns an error for the same reason mentioned in the previous point.

Path parameters

Name
Description
group_property Required. Name of the group property. Prefix custom group properties with grp:. Amplitude-sourced group properties (names without the grp: prefix) aren't editable.

Body parameters

Name
Description
group_type Optional. Name of the group type the group property belongs to. If the group type doesn't exist, Amplitude returns a 404 Not Found error.
overrideScope Optional. Determines how we should act on this group property. Only applicable if group_type is present. If overrideScope is not present, Amplitude updates property override on the group type if it exists on the group type, or the shared property if no override exists on the group type. With overrideScope: "override", Amplitude creates an override if none exists on the group type, then updates that overridden property, or updates the existing override if one already exists. With overrideScope: "shared", Amplitude removes the property override on the group type if one exists on the group type, then updates the shared property, or it updates the shared property if no property override exists.
description Optional. String. Description of the group property.
new_group_property_value Optional. String. The new name of the group property.
type Optional. String. Data type of the group property. It must be one of any (default), string (default if array type is true), number, boolean, enum
regex Optional. String. Regular expression, custom regex used for pattern matching or more complex values. For example, property zip code must have pattern [0-9]{5} Applies only to the string type.
enum_values Optional. String. List of allowed values, separated by comma. For example: red, yellow, blue. Only applicable to the enum type.
is_array_type Optional. Boolean. Property is an array type. Use the type parameter to set the type of array elements.
classifications Optional. String. Only available if Data Access Controls is enabled at the account level. List of classifications applicable to this group property. Valid classifications are PII, SENSITIVE and REVENUE. You can only apply classifications on shared properties. Trying to set classifications on an overridden property results in an error.
