In GraphQL, you can pass a unique identifier as an argument in your query by defining it in the query's input variables. Here is an example of how you can do this:

1. Define your query with an input variable for the unique identifier:

1
2
3
4
5

query GetItemById($itemId: ID!) {
  getItem(id: $itemId) {
    id
    name
    description
  }
}

1. Pass the unique identifier as part of the query's variables when executing the query:

1
2
3

{
  "itemId": "unique-id-123"
}

1. Make the GraphQL query request with the input variable:

1
2
3
4
5
6

GET /graphql

{
  "query": "GetItemById",
  "variables": {
    "itemId": "unique-id-123"
  }
}

By following these steps, you can pass a unique identifier as an argument in your GraphQL query. This allows you to retrieve specific data based on the unique identifier provided.
