API Design · Junior · Question 74 of 75

How can a client fetch several users by ID in one request in a REST API?

1By sending three GET requests in one HTTP body
2It's impossible in REST
✓Correct answer: With a filter on the collection, e.g. GET /users?ids=1,2,3, within a documented maximum

Explanation

Batch reads reduce round trips. Large ID lists may need POST /users:batchGet with a body because URLs have length limits.
