Description: The mutation input in GraphQL defines the structure of the data that can be sent to a mutation operation. Unlike queries, which are used to retrieve data, mutations allow for modifications to the server’s state, whether by creating, updating, or deleting data. This input specifies the required and optional fields that the client must provide when performing a mutation. The definition of the mutation input is done in the GraphQL schema, where data types and their relationships are established. This provides a clear and structured way to interact with the API, ensuring that the data sent is valid and meets the server’s expectations. Additionally, mutation inputs can include validations and constraints, helping to maintain data integrity. In summary, the mutation input is an essential component in GraphQL that allows developers to define how data can be modified in applications efficiently and securely.
