Asset-scoped actors can manage headers only when every domain in the existing and requested scopes is accessible. Only unrestricted actors can set an empty scope for all domains. Strix encrypts values and never returns saved values. Empty or omitted values keep the saved value on update. ## OpenAPI ````yaml /openapi.json patch /domains/{domainId}/scan-headers/{headerId} openapi: 3.1.0 info: title: Strix API version: 1.0.0 description: >- Public REST API for the Strix autonomous penetration testing platform.
