Update Project DLP Settings
Replace the project’s DLP override as a whole. Entity types you omit inherit the organization’s rule; an empty override means inherit everything, the same as DELETE. A project pinned to an API key uses this policy as written. A project named per request (project_id body field or X-Project-Id header) can only tighten the organization policy; anything that loosens it is ignored at request time.
Needs manage_security_rules or manage_projects.
Authentication
A management key (mgmt_...), sent as Authorization: Bearer <key>. Reading /v1/routing-policies also accepts the organization’s gateway API keys; writing there needs a management key.
Path parameters
The project’s id.
Request
Keyed by entity type, like US_SSN. Each must exist in the organization’s rules, seeded or custom. An empty map clears the override.
