Omit filter[status] to return all statuses. Only published protocols can be used to create experiments. This endpoint requires the `product_analytics_experiments_read` permission. OAuth apps require the `product_analytics_experiments_read` authorization [scope](https://dnd37xeb23o8n.cloudfront.net/stefon.simmons/docs-astro-web-10435/es/api/latest/scopes.md#experiments) to access this endpoint. ### Arguments #### Query Strings | Field | Type | Description | | ------------------------- | ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | filter[status] | array | Filter by protocol status. Repeat this parameter to select more than one status. | | filter[primary_metric_id] | string | Filter by the UUID of the primary metric in the protocol template. | | filter[query] | string | Find protocols whose names contain the search text, regardless of case. Leading and trailing spaces are ignored. Blank values apply no filter. The maximum length is 1024 UTF-8 bytes. | | filter[subject_type_id] | string | Filter by the UUID of the subject type in the protocol template. | | page[limit] | integer | Number of results per page. The default is 25. Values above 50 are reduced to 50. | | page[offset] | integer | Number of results to skip before returning this page. | | sort | string | Sort by `name`, `subject_type_name`, `primary_metric_name`, or `updated_at`. Prefix with `-` for descending order. The default is `-updated_at`. | ### Response {% tabs %} {% tab label="200" %} OK {% tabs %} {% tab label="Model" %} List of protocol resources with pagination information. | Parent field | Field | Type | Description | | -------------- | ----------------------- | -------- | ---------------------------------------------------------------------------------------------------- | | | data [*required*] | [object] | Resources returned in this response. | | data | attributes | object | Summary of the protocol and its selected subject type and primary metric. | | attributes | description | string | Text that explains the protocol. | | attributes | name [*required*] | string | Display name of the protocol. | | attributes | primary_metric | object | Subject type selected by the protocol. | | primary_metric | id | string | ID of the subject type. | | primary_metric | name | string | Display name of the subject type. | | attributes | primary_metric_id | string | ID of the primary metric supplied by the protocol. | | attributes | status [*required*] | enum | Publication status of the protocol.
