GraphQL - Mutations

You want to delete multiple users by their IDs in one mutation call. Which approach correctly applies the delete mutation pattern?

Options:

mutation { deleteUsers(ids: ["1", "2", "3"]) { success message } }
mutation { deleteUser(id: "1") { success message } deleteUser(id: "2") { success message } }
mutation { deleteUser(id: "1") { success message } }
mutation { deleteUsers(ids: "1,2,3") { success message } }

ACall deleteUser mutation multiple times in one request

BPass IDs as a comma-separated string in deleteUsers(ids: "1,2,3")

CDelete only one user at a time with deleteUser(id: "1")

DUse a single mutation with an array of IDs: deleteUsers(ids: ["1", "2", "3"])

Step-by-Step Solution

Solution:

Step 1: Understand batch deletion
To delete multiple users at once, the mutation must accept an array of IDs.
Step 2: Evaluate options
Use a single mutation with an array of IDs: deleteUsers(ids: ["1", "2", "3"]) correctly passes an array of strings. Call deleteUser mutation multiple times in one request tries multiple mutations in one call, which is invalid syntax. Delete only one user at a time with deleteUser(id: "1") deletes only one user. Pass IDs as a comma-separated string in deleteUsers(ids: "1,2,3") passes a string instead of an array.
Final Answer:
Use a single mutation with an array of IDs: deleteUsers(ids: ["1", "2", "3"]) -> Option D
Quick Check:
Batch delete uses array of IDs [OK]

Quick Trick: Batch deletes use array arguments, not comma strings [OK]
