Summary Definitions

The Summary Definitions authoring UI has been retired. The endpoints below still work, but the GET /api/v1/summary-definitions read endpoint now exists only to power the customer viewer’s summaries filter. For behavioral aggregation, use Behavioral Metrics instead.

See also: Summary Definitions concept and configuration for what this API powers, when to call it, and how it is configured.

Overview

Summary definitions control how raw interaction events are aggregated into daily/weekly/monthly buckets. Each definition specifies which dimensions to group by and which time windows to maintain.

List Summary Definitions

GET /api/v1/summary-definitions

Returns all summary definitions for the current tenant, ordered by system definitions first, then alphabetically.

Request Body

Field	Type	Required	Description
`name`	string	Yes	Unique name for the definition

`last_contact`	Timestamp of last contact
`distinct_offers`	Count of distinct offers

Example

{
  "name": "Channel Performance Tracker",
  "description": "Track offer performance per channel with daily and weekly rollups",
  "dimensions": ["offer_id", "channel_id"],
  "aggregates": ["count", "sum_value"],
  "windows": ["1d", "7d"],
  "status": "active"
}

Response `201`

Returns the created summary definition with id, isSystem: false, and timestamps.

Error codes

Code	Reason
`400`	Missing name, invalid dimensions/aggregates/windows, or duplicate name.

Update Summary Definition

PUT /api/v1/summary-definitions

Request Body

Field	Type	Required	Description
`id`	string	Yes	Summary definition ID
`name`	string	No	Updated name
`description`	string	No	Updated description
`dimensions`	string[]	No	Updated dimensions (cannot change on system definitions)
`aggregates`	string[]	No	Updated aggregates
`windows`	string[]	No	Updated windows
`status`	string	No	`active` or `inactive`

System summary definitions (those flagged isSystem: true) cannot have their dimensions changed. Attempting to change them returns a 400 error. You can update the name, description, aggregates, windows, and status.

Response `200`

Returns the updated summary definition.

Error codes

Code	Reason
`400`	Missing `id`, invalid dimensions/aggregates/windows, duplicate name, or attempting to change system definition dimensions.
`404`	Summary definition not found.

Delete Summary Definition

DELETE /api/v1/summary-definitions?id={id}

Deletes a summary definition. System definitions cannot be deleted.

Query Parameters

Parameter	Type	Required	Description
`id`	string	Yes	Summary definition ID to delete

Response

{ "deleted": true }

Error codes

Code	Reason
`400`	Missing `id`, or attempting to delete a system definition.
`404`	Summary definition not found.

Summary definitions are an inert config surface — no aggregation engine reads them (see the retired-feature note). Deleting one only removes the descriptive record; it does not start or stop any aggregation. For behavioral aggregation, use Behavioral Metrics.

Role requirements

Method	Minimum role
GET	`viewer`
POST	`admin`
PUT	`admin`
DELETE	`admin`

System definitions

Summary definitions flagged isSystem: true are treated as protected system definitions. They:

Cannot have their dimensions changed (the API returns 400 if you try).
Cannot be deleted (the API returns 400).
Can have their name, description, aggregates, windows, and status updated normally.
Are listed first in GET responses (ordered by isSystem descending, then alphabetically by name).
