Any

Arbitrary JSON value scalar type

Audience: Programmer

The Any scalar type represents an arbitrary JSON value of any type - object, array, string, number, boolean, or null.

Format

• Accepts any valid JSON value

• Can be object, array, primitive, or null

• No schema validation

• Serialized as JSON

Usage

type WorkflowSignal {
  id: ID!
  name: String!
  payload: Any  # Can be any JSON value
}

mutation {
  createWorkflowSignal(input: {
    name: "process_order"
    payload: {
      "orderId": "12345",
      "items": [
        {"sku": "ABC", "qty": 2},
        {"sku": "XYZ", "qty": 1}
      ],
      "priority": 1,
      "rush": true
    }
  }) {
    signal {
      id
      payload
    }
  }
}

Valid Values

All of these are valid Any values:

# Object
payload: { "key": "value" }

# Array
payload: [1, 2, 3]

# String
payload: "simple string"

# Number
payload: 42.5

# Boolean
payload: true

# Null
payload: null

Use Cases

• Workflow payloads with dynamic structure

• Configuration objects

• Event data with varying schemas

• Integration payloads

• Backwards compatibility

Best Practices

1. Use sparingly - prefer typed fields when possible

2. Document expected structure

3. Validate on the server side

4. Consider using Map for object-only data

5. Version your payload structures

Comparison with Map

• Any: Accepts any JSON value (objects, arrays, primitives)

• Map: Only accepts JSON objects
