Could not find the webhook topic customer.tags_added

Hi Guys,

I am trying to subscribe to customer.tags_added via REST API (have tried various versions, including the latest 2025-07), but we are getting a 404 error with “Could not find the webhook topic customer.tags_added” message. Is there any information available on whether this now only works with GraphQL? Documentation does not really say that, so I’m assuming Rest APIs work for subscribing to customer.tags_added

Looks like this only works with Graphql

This doesn’t answer your question, but the REST Admin API has been deprecated. Please use GraphQL Admin API.

Hey @Kets_Patel, as Remy mentioned, our REST API’s are legacy, meaning no new functionality will be added to them. Subscribing through Graphql or your app configuration file are the recommended methods.

If you need to use REST though, the event to subscribe to for when a tag is added is customers/update

thanks guy, I have changed to use Graphql and its all good
