Issue while attaching fulfillment service to the default variant when creating a new product

Product Development & Sourcing

We can’t attach a fulfillment service to the default variant when creating a new product. In the latest API version, updating the fulfillment service for a product variant isn’t supported. As a workaround, we’ve been using an older version of the GraphQL API that still allows fulfillment service updates. However, since that older API version is being deprecated, we need to find another solution going forward.

Hi @krishna1611

Since Shopify is disapproving the older GraphQL API version that allows fulfilment service updates for product variants.

You can try using following steps:

  1. Manually Assign Fulfillment Services After Product Creation
  2. Use Shopify’s REST API for Fulfillment Service Management
    3)Use Shopify Flow or a Custom App
  3. Leverage Webhooks for Post-Processing

Let me know if you need more assistance.
