For some operations, you can use specific endpoints provided by the Rulesets API for managing phase entry point rulesets. These endpoints include the phase name in the endpoint instead of the ruleset ID.

For example, instead of using the following endpoint:

PUT /zones/{zone_id}/rulesets/{ruleset_id}

You can use the following endpoint:

PUT /zones/{zone_id}/rulesets/phases/{phase_name}/entrypoint

To invoke a Rulesets API operation, append the endpoint to the Cloudflare API base URL:

For authentication instructions, refer to Getting Started: Requests in the Cloudflare API documentation.

For help with endpoints and pagination, refer to Getting Started: Endpoints.
