Update facility overview fields on a workflow

Updates selected overview fields on the facility credentialing workflow. Supported fields: dba, name, primaryEmail, npi, tin, externalId, facilityType, attestationDate. When to use: Use to correct or refresh basic facility metadata stored on the workflow. Fields omitted from the request body are left unchanged (null fields are ignored). Note on semantics: Although this is a PUT, the endpoint behaves like a partial update — only fields explicitly provided are modified. This is non-standard for PUT; treat the supplied fields as the desired state for those specific fields only. Returns: 200 OK with the updated workflow.
