How to leverage GraphQL to improve Data Gathering in Salesforce? GraphQL is a query language and runtime for APIs that allows clients to request specific data structures. Unlike REST, which delivers fixed data responses, GraphQL enables users to get exactly what they need in a single request.
What is GraphQL?
GraphQL is a query language for APIs and a runtime for executing those queries by using a type system you define for your data. It allows clients to request only the data they need, making it more efficient than traditional REST APIs, where the server defines the structure of the responses. With GraphQL, developers can specify exactly what data they require when making a request, reducing the amount of data transferred over the network.
- Query language specification & runtime for APIs
- Single endpoint for all resources to be aggregated
- Efficient because only necessary data is requested
GraphQL also supports nested queries, where you can request related data in a single query rather than making multiple requests. This flexibility and efficiency make it popular for building modern web and mobile applications. Additionally, it provides a strong type system, which helps in documenting APIs and ensuring the correctness of the data returned.
How is it different from REST APIs?
- REST uses specific API endpoints to fetch different types of data
- Contains the probability of over-fetching or under-fetching data

- GraphQL has the same query limitations as SOQL.
