Hi @AVeremjova,
The issue you’re facing when building a deal-based workflow with Line Items for first-time buyers of Product A and Product B is likely related to how HubSpot handles Line Item properties in workflows. Since the workflow cannot be contact-based due to the use of non-HubSpot forms, Ensure the correct Line Item properties, such as product type (Product A or B), are included and properly mapped to the deal in HubSpot. In the workflow, set deal triggers like “Deal stage” and “Line Item contains Product A or B” to accurately reflect the deal status and product purchased.
Best regards!
