Tag product when webhook received

When a supplier, PIM or ERP calls your webhook with a SKU and a tag, add that tag to the product. Keeps collections, filters and badges in sync with data from outside Shopify.

One trigger from Workflow Webhooks and Shopify's built-in actions, no other app needed.

The workflow in Shopify Flow: Tag product when webhook received
The complete workflow as it looks in Shopify Flow.

What it needs

A webhook in Workflow Webhooks with this payload mapping. See Payload mapping and Flow variables.

Field What to map to it
fieldOne The variant SKU, for example TSHIRT-RED-M
fieldTwo The tag to add, for example back-in-stock

A call to the webhook then looks like this:

bash
curl -X POST https://<your webhook URL> \
  -H "Content-Type: application/json" \
  -d '{"sku": "TSHIRT-RED-M", "tag": "back-in-stock"}'

Get the workflow

  1. Download the .flow file attached at the bottom of this page.
  2. In your Shopify admin open Flow, click Import and choose the file.
  3. Check the steps, then click Turn on workflow.

The file is an export from Shopify Flow itself. Do not edit it by hand; change the workflow in Flow after importing it.

How it works

  1. Webhook Trigger starts the workflow each time your webhook URL is called and hands it the mapped fields.
  2. Get product variant data looks up the variant with the query sku:{{fieldOne}} and keeps at most one result.
  3. For each runs once for the variant it found, and not at all when no SKU matches.
  4. Add product tags adds {{fieldTwo}} to the product of that variant.

Make it yours

  • Replace {{fieldTwo}} with a fixed tag such as supplier-update if the caller cannot send a tag.
  • Use Remove product tags instead to clear a tag, for example when a supplier reports stock again.
