What you get

What Gelato gives your agent

The tools, permissions, and events Gelato exposes — the same ones your agent can use once the app is authorized.

What you sign in with

Gelato connects with API_KEY.

Permissions

Gelato does not break access down into granular permissions.

Tools Gelato exposes

GELATO_CANCEL_ORDER

Cancel Order

Cancel a regular Gelato order before production advances too far. DESTRUCTIVE: cancellation is an irreversible lifecycle change and may fail with conflict once the order is printed or shipped. Confirm the target order and do not retry blindly.

GELATO_CHECK_STOCK_AVAILABILITY

Check Stock Availability

Check current regional stock status for 1 to 250 Gelato product UIDs. Availability is volatile; call near quote or order time and do not treat an earlier result as a reservation.

GELATO_CREATE_DRAFT_ORDER

Create Draft Order

Create a Gelato draft for review or later submission without entering production. Use a unique order_reference_id; delete the draft when it is no longer needed.

GELATO_CREATE_ORDER

Create Order

Create a production order that can immediately enter fulfillment and charge the connected account. IRREVERSIBLE: call only after explicit purchase authorization, use a unique order_reference_id, and never retry an ambiguous result.

GELATO_DELETE_DRAFT_ORDER

Delete Draft Order

Permanently delete a Gelato draft. DESTRUCTIVE: only use for a confirmed draft, preferably one created by the same workflow; this cannot delete a regular production order and success was not live-exercised.

GELATO_GET_CATALOGS

Get Catalogs

List available Gelato product catalogs, or provide catalog_uid to retrieve one catalog's full product-attribute definitions and allowed values. Use detail mode before constructing attribute filters.

GELATO_GET_ORDER

Get Order

Retrieve the full current state, financial status, fulfillment status, shipment tracking, items, and totals of one Gelato order by its Gelato order ID.

GELATO_GET_PRODUCT

Get Product

Retrieve one Gelato product's attributes, dimensions, weight, supported countries, printability, stockability, content areas, and valid page counts by product UID.

Example prompts

  • Use Gelato to check recent changes and summarize them in the issue.
  • When a customer writes in, pull their data from Gelato before replying.
  • Audit our open items in Gelato and notify the channel of anything stale.
