External webhook in Shopify Flow for tagging customers

Today we want to show you how to add a tag to a customer in Shopify using an external webhook.

You need our Shopify App Flow Webhooks and the official Shopify Flow App .

The first step requires a webhook. We've opted for static authentication here (a token in the X-Api-Key header). We've entered the email and tag in the mapping so that the external call is visible.

To match this webhook, we have created a flow in Shopify Flow:

This flow consists of the following steps:

• Webhook triggers
• Condition that WebhookId matches the ID of the webhook (here cmaiow2uc000145423ail4ejh )
• Search for the customer via a query (here {{fieldOne}} , is mapped to email via our webhook)
• A For each loop over all results (there should always be only one customer here, as this customer can be clearly identified via the email)
• Action "Add customer tags" with {{fieldTwo}} (mapped to tag via our webhook)

If everything is correct, give the flow a comprehensible name and activate it.

Now copy the curl command from your webhook and execute it. In our case, it looks like this:

If everything went well, you should now see a successful execution in Shopify Flow.

For us it looks like this:

At the very end, you can check whether the new tag has been added to the customer.

As you can see, you can build very powerful automation with relatively simple means.
