Get All Scenarios¶

GET scenarios/¶

Note

Authorized Roles: root, manager, backend

Return all scenarios [see About Scenarios]. The result is paginated and it allows to use filters by reco_type, scenario_type or metadata content.

The response is paginated, you can control the response amount and offset using the query parameters amt and cursor.

Query Parameters

cursor (string) – Optional. Pagination cursor, typically from the next_cursor value from the previous response
amt (int) – Optional. [min: 1 max: 512] Amount of scenarios to return
reco_type (enum) – Optional. choices: [item_to_items, profile_to_items, session_to_items, profile_to_item_properties, profile_to_items_w_ctx_items, session_to_items_w_ctx_items, precomputed_item_to_items, precomputed_profile_to_items, session_to_item_properties, profiles_group_to_items, chat_to_items, item_properties_to_items, generic_input_to_items, llm_text_completion, llm_chat_completion] Filter by reco type
scenario_type (enum) – Optional. choices: [case, ab_test, condition, alias] Filter by type of scenario
metadata_filters (list-of-object) –
Optional. Filter by metadata content. The result is the conjunction of the filter list, meaning the filters are concatenated with AND.
In URL-compatible format, use . to denote nested levels within the JSON object in keys part, and use \. to escape a . in keys, and \ to escape \. [see URL-Compatible Format]
Inner fields
- keys (list-of-string) – Keys of the metadata content. Each value in the list represents a nested level within the JSON object
- op (enum) – choices (case insensitive): [eq, lt, gt, lte, gte] Filter Operator
