What is GraphQL vs REST for Salesforce headless apps?
Real World Scenario
Mobile app developers ask which API style to use for fetching product and customer in one screen load.
Expected Answer
• REST exposes resource endpoints—you may need multiple calls for related data
• GraphQL lets clients request specific fields in one query, reducing over-fetching
• Salesforce offers GraphQL for some data access patterns depending on product
• REST is more universal and better documented for most Salesforce integrations
• Choose based on team skills, payload size, and supported Salesforce APIs for your use case
