How to implement a GraphQL mutation
Blog post from Postman
GraphQL mutations are essential operations for modifying server-side data, allowing users to create, update, or delete data as defined within a GraphQL schema. These mutations are complemented by resolver functions that execute the data modification logic when a mutation is triggered. Utilizing variables in mutations enhances reusability and security by preventing injection attacks, as variables are specified alongside the query or mutation and allow dynamic input. Postman's GraphQL client supports dynamic testing of mutations by enabling the use of variables and scripts to test various scenarios and workloads, with features like variable workflows and sample data generation through its built-in faker library. This combination of dynamic testing capabilities and robust mutation handling makes GraphQL mutations a powerful tool for developers looking to implement and test write operations in GraphQL APIs.
