Create Line Items for a Deal during a Workflow Custom Code Block

BHooker — Fri, 07 Apr 2023 11:25:24 GMT

Goal is to add a set of line_items to a deal using a workflow custom code block. A set of SKUs will be passed in. Approach is to add the line items, and then associate them with the deal. The Products already exist in the product object, so we can reference hs_sku or hs_product_id as required.

Getting an error when running the crm.line_items.create method.

It looks like the crm.line_items methods are being blocked or erroring.

Can anyone assist?

Details:

Workflow: After deal created, this workflow and action is run

Language: node.js 16.x

Private App: has read and write access to crm.deals and crm.line_items

Client: Hubspot Client v8

Custom Code:

Error:

Hi.

You should use func `crm.lineItems.create`.

https://github.com/HubSpot/hubspot-api-nodejs/blob/master/codegen/crm/line_items/apis/BasicApi.ts#L70

And you should change `lineItemInput`.

https://github.com/HubSpot/hubspot-api-nodejs/blob/master/codegen/crm/line_items/models/SimplePublicObjectInput.ts#L14

This is sample code.

// /crm/line_items/models/SimplePublicObjectInput const lineItemInput = { properties: { name: 'Main product', quantity: 1, price: 140000.0 }, }; hubspotClient.crm.lineItems.basicApi.create(lineItemInput) .then((createdLineItem) => { // do something with the created line item }) .catch((err) => { console.error(err); });

Thanks.

Hi @BHooker,

I want to share a product update here which might make a custom code action obsolete - it makes automation of line items a lot easier: https://app-eu1.hubspot.com/l/product-updates/?rollout=281984

Add Line Items to Deals via Workflow Actions

What is it?

You now have access to a new workflow action that lets you automatically add line items to a deal.Within a workflow, you can:

Select a specific product from your product library
Set a quantity
Automatically attach that line item to the deal when the workflow runs

This brings product and pricing logic directly into your automations. No manual deal updates required.

Why does it matter?

Before this, adding products to deals required manual work or post-automation cleanup. Now, you can:

Fully automate deal setup the moment a trigger fires
Ensure consistent products and quantities are applied every time
Reduce human error and save time for sales and ops teams
Build more advanced revenue workflows (e.g. auto-adding onboarding fees, setup packages, or standard bundles)

This is a huge unlock for automation, especially for teams standardizing how deals are created.

How does it work?

Create or edit a Deal-based workflow
Add the new Add line item to Deal action
Select a product from the product library
Set the default quantity
Publish the workflow

When the workflow runs, a line item is created with the selected product and quantity and associated with the Deal automatically.
