Create an approval step
Platform module
POST/approval-stepsapprovalSteps.create
An ordered step of an approval policy (1030). It names its approvers: everyone holding a role, or one member. Steps change only while the policy is a Draft (approval_step_policy_not_draft: 422). Creates an approval step. Requires `Idempotency-Key`; a replay returns the original response. The organization is derived from the credential or the parent row, never from the body.
- Requires the capability org.approval_policies.write.
- OAuth scopes: org.
- Send an Idempotency-Key header. A replay with the same key returns the original response.
- Error statuses: 400, 401, 409, 422, 429. Errors are RFC 9457 problem details.
