Policy Set Parameters API

Sentinel parameters are a list of key/value pairs that HCP Terraform sends to the Sentinel runtime when performing policy checks on workspaces. They can help you avoid hardcoding sensitive parameters into a policy.

Parameters are only available for Sentinel policies. This set of APIs provides endpoints to create, update, list and delete parameters.

Create a Parameter

POST /policy-sets/:policy_set_id/parameters

ParameterDescription
:policy_set_idThe ID of the policy set to create the parameter in.
