Create a rule via API
Use the Rulesets API to create a compression rule via API.
When creating a compression rule via API, make sure you:
- Set the rule action to compress_response.
- Define the parameters in the action_parametersfield according to the settings you wish to override for matching requests.
- Deploy the rule to the http_response_compressionphase at the zone level.
Follow this workflow to create a compression rule for a given zone via API:
- 
Use the List zone rulesets operation to check if there is already a ruleset for the http_response_compressionphase at the zone level.
- 
If the phase ruleset does not exist, create it using the Create a zone ruleset operation. In the new ruleset properties, set the following values: - kind: zone
- phase: http_response_compression
 
- kind: 
- 
Use the Update a zone ruleset operation to add a compression rule to the list of ruleset rules. Alternatively, include the rule in the Create a zone ruleset request mentioned in the previous step. 
For example API requests, refer to the Examples gallery.
