domain: developer.salesforce.com · 6 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed
Verified steps Annotate an Apex class with @RestResource(urlMapping='/myresource/*') and mark methods with @HttpGet or @HttpPost Use RestContext.request and RestContext.response to access the raw request body, path parameters, and set status codes Define inner Apex classes for request and response payloads and use JSON.deserialize / JSON.serialize for marshalling Deploy the class and verify the endpoint is accessible at /services/apexrest/<namespace>/myresource/ Call the endpoint externally using a connected app OAuth token in the Authorization header Write Apex test methods that set RestContext.request manually to achieve code-coverage without making real HTTP calls Known gotchas The urlMapping must start with a forward slash and must be unique across the org; duplicate mappings cause a deployment error Apex REST methods must be global static; non-static or public-scoped methods are silently ignored by the runtime RestContext is not populated during standard Apex unit tests unless you manually assign a RestRequest to RestContext.request before calling the method
