Create map field - Automate.ax

axiom.createMapField marks one existing field as a map field and returns its name. This changes indexing, not retained event values.

automations/axiom-create-map-field.automation.ts

import { automation, onHttpRequest } from "automate.ax"
import { axiom } from "automate.ax/axiom"

export default automation("Create map field", () => {
  onHttpRequest({ scope: "automation" })
  axiom.createMapField({ datasetName: "production", fieldName: "attributes" })
})

Inputs

datasetName selects the dataset by name or ID. fieldName is the existing field to mark as a map field.

Output

Returns { name: string } for the configured map field.

Permission and failures

The API token needs the organization-level datasets|update capability and access to the target dataset. Axiom rejects missing datasets, unknown fields, and fields that cannot be configured as maps. This mutation is not retried automatically after an ambiguous provider response.
