Description: A mutation argument is a parameter passed to a mutation in GraphQL that allows specifying the input data needed to change the server’s state. Unlike queries, which are used to retrieve data, mutations are operations that modify existing data or create new data. Mutation arguments are essential for defining what information is needed to carry out the desired operation. For example, when creating a new user, arguments such as name, email, and password may be required. These arguments are defined in the GraphQL schema and are crucial for ensuring that the mutation receives the correct information in the appropriate format. Validating these arguments is vital, as it ensures that the data is consistent and meets the established business rules. In summary, mutation arguments are an integral part of interacting with GraphQL APIs, allowing developers to specify clearly and precisely the data they want to modify or create on the server.
