REST API Data Sources

REST API data sources let you define a named connection to an external HTTP API. Optionally provide an OpenAPI spec for endpoint auto-discovery and IntelliSense in the script editor.

Creating an API data source

1. Go to Data Sources → New Data Source
2. Select REST API
3. Fill in:
   • Name — used to reference this data source in scripts (e.g. ShopifyAPI)
   • Base URL — the root URL of the API (e.g. https://api.shopify.com/v1)
   • Auth — see Auth & Credentials
   • OpenAPI Spec (optional) — paste a JSON or YAML OpenAPI spec for endpoint discovery
4. Click Test Connection — makes a HEAD or GET request to the base URL
5. Save

Using in scripts

If you provided an OpenAPI spec, endpoints are available as methods on the datasource object:

JavaScript / TypeScript:

// Auto-generated from OpenAPI spec
const products = await datasources.ShopifyAPI.getProducts({ limit: 50 })
logger.info(`Products: ${products.length}`)

PowerShell:

$products = $datasources.ShopifyAPI.GetProducts(@{ limit = 50 })
$logger.Info("Products: $($products.Count)")

Without an OpenAPI spec, use fetch / Invoke-RestMethod directly with authHeaders for auth.

IntelliSense

When an OpenAPI spec is present, the Monaco editor shows autocomplete for endpoint names and parameter types as you type datasources.YourApiName..
