The eventual draftOrderCreate/orderCreate happens in the separate 'Order - create' op.) - Action **Order - add line item tax line** Adds a tax line to the last line item of an in-memory order payload (builder, no API call). This op shapes the legacy order JSON structure; it does not call Shopify. Same inputs/outputs as the REST builder.

Uses the GraphQL Admin API tagsRemove mutation; tags not present are ignored.

Any of Pennylane's 5 triggers in the catalog, including New Billing Subscription V2, New Customer Invoice V2, New Customer V2 and New Product V2. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Shopify when something happens in Pennylane? Any of Shopify's 78 actions, including Create Metafield Definition, Create Order with Calculated Tax, Create or Update Theme File and Create product. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Shopify to Pennylane? Yes. When something happens in Shopify, your agent can act in Pennylane too. This page covers both directions: Shopify's triggers and Pennylane's actions are listed here as well. ### ### Do I have to build a connector for Pennylane or Shopify? No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running. ### ### Can my AI client use Pennylane and Shopify without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
