Using Variables

In GraphQL, every field and nested object can get its own set of dynamic variables. The variable type is declared in the schema, or on Voyager.

To use these variables, we need to:

1. Replace the static value in the query for $variableName : type

2. Declare $variableName as one of the variables accepted by the query

3. Pass variableName : value in the separate variables dictionary.

Supply Example:

The variable type as seen in Voyager has been circled in red, below.

query searchManyPart($q: [SupPartMatchQuery!]!) {
  supMultiMatch(
    queries: $q,
    currency: "GBP"
    country: "GBR"
  ) {
    hits
    parts {
      mpn
      sellers {
        company {
          name
        }
        offers {
          prices {
            convertedPrice
            quantity
          }
        }
      }
    }
  }
}

{
  "q":[
{'start': 0, 'limit': 1, 'mpn': 'ML-1220/F1AN'},
{'start': 0, 'limit': 1, 'mpn': 'ERJ-2RKF1003X'},
{'start': 0, 'limit': 1, 'mpn': 'EEE-FK1E101XP'}]
}

query getProjectBoM($projectId: ID!) {
  desProjectById(id: $projectId) {
    id
    name
    tasks {
      id
      name
      description
      status
    }
  }
}

{
  "projectId": "RGVzUH..."
}
