Partially update task product

What this endpoint does: Updates an existing product that has been imported into a task. This endpoint supports partial updates - you only need to provide the fields you want to change. All other fields remain unchanged.

What can be updated:

  • Basic information: Name, description (HTML or Markdown), category, logo
  • Pricing: Fixed price, subscription price, per-unit price, unit name, billing frequency
  • Variants: Add, update, or modify product variants (e.g., Standard, Pro, Enterprise versions)
  • Options: Modify product options and their values (e.g., additional services, upgrades)

Important notes:

  • This is a PATCH operation - only provided fields are updated
  • Description can be provided as HTML or Markdown - it will be automatically converted to the internal document format
  • Variant descriptions also support HTML or Markdown
  • When updating variants, you must provide the complete variant structure (existing variants are replaced)
  • When updating options, you must provide the complete options structure (existing options are replaced)
  • Changes only affect the product within this task - the catalog product remains unchanged
  • Product must belong to the specified task

Pricing models:

  • Fixed price: One-time payment amount
  • Subscription price: Recurring payment (e.g., monthly, yearly)
  • Price per unit: Calculated per quantity (e.g., per user, per hour)
  • Price frequency: Billing interval for subscriptions (in months)

What is returned: Returns success status and the product ID.

Permission requirements: Requires “manageProducts” permission on tasks and “api” scope.
