Implementing mutation operations for an API requires careful consideration of both REST and GraphQL paradigms. Below is the specification structured with GraphQL being the underlying technology.
Create Resource
As an API consumer, I want to be able to create a new resource in the system so that I can expand the dataset.
Acceptance Criteria
[ ] The API should allow creating a new resource with necessary attributes.
[ ] The API should validate input data according to predefined schema.
[ ] The API should return an error if required fields are missing.
[ ] The API should return the created resource object with a unique identifier.
[ ] The API should prevent unauthorized users from creating a resource.
[ ] The API should handle concurrent create requests gracefully.
[ ] The API should respond with appropriate HTTP/GraphQL status codes on success or failure.

API->>Client: Create resource and assign unique ID
API->>Client: Return created resource object
Update Resource
As an API consumer, I want to be able to update an existing resource so that I can keep the data current.
Acceptance Criteria
[ ] The API should allow updating a resource partially (PATCH) or completely (PUT).
[ ] The API should check for the existence of the resource before updating.
[ ] The API should validate input data before updating the resource.
[ ] The API should return an error if the resource does not exist.
[ ] The API should return the updated resource object after successful update.
[ ] The API should ensure user has proper authorization to update the resource.
[ ] The API should lock the resource during the update to prevent race conditions.
[ ] The API should return appropriate HTTP/GraphQL statuses for success or failure operations.
