Update a project

MCP id projects.updateAlso on this path: GET Read a project, DELETE Delete a project

Partially updates a project: absent keys are untouched and an empty body is rejected.

Token scope: api:write:projects
Without it: 403 insufficient-token-scope.
Permission: projects::update
Without it: 403 insufficient-permission.
Rate cost: 1 unit, write bucket. A write costs the same whatever view you ask for.
Also: Accepts If-Match. Never cached: private, no-store. Unknown body keys are refused, never dropped.

Both are checked, scope first. A token never does more than its user. How access is checked

Setting status to invoiced also finishes every task on every budget of the project, in the same write. account_manager_id and application_id are not accepted, and a project's workflow is changed in plnnrly. tag_ids replaces the tag set whole; an empty array clears it. Send If-Match with the ETag from your last read to detect a concurrent edit, which answers 412.
