Custom query for filter in Get Customer Data action

Shopify Plus

Topic summary

A user needed to filter customers by tag in Shopify Flow’s Get Customer Data action but struggled with the correct query syntax.

Attempted solutions that failed:

  • query=tags:EdTest
  • tags:EdTest
  • tag=EdTest
  • query=tag:EdTest

The user referenced Shopify’s GraphQL API documentation on filter parameters, which indicated tag filtering should be possible, but couldn’t determine the proper syntax from the documentation alone.

Resolution:
The correct syntax is tag:EdTest (without the “query=” prefix and using singular “tag” with a colon). This successfully filters the customer list to show only those with the specified tag.

Note: Some responses suggested private consultation rather than public solutions, which the original poster rejected in favor of keeping answers accessible to the community.

I need to filter the list of customers returned by the Get customer data action according to whether a customer has a specific tag. I have tried the syntax

query=tags:EdTest

and all variations that I can think of; but nothing filters the list successfully.

According to the documentation on filter parameters shown here, I ought to be able to do this somehow. What am I doing wrong?

Can’t you explain the solution here so that everyone else can benefit as well?

Thank you for your reply. As per my original question, I’m interested in scenario #3. In particular, I want to know how to craft a custom query for a filter in the Get Customer Data action. Please see the screenshot(s) in my question above for more details.

This is a community forum: questions are asked and answered for the benefit of everybody; therefore the replies need to be public. If you are unwilling to offer your help under these conditions, please don’t respond any further - there are more appropriate ways to advertise private consultancy services.

Thank you for your reply. However, as explained in my original question, I have already tried to adjust the filters directly in the action settings - but without success. Please see the first screenshot in my question above. I have tried tag:Edtest, tags:Edtest, query=tag:Edtest and query=tags:Edtest in the action settings; but none of these filters my list of customers according to the presence of the tag “EdTest”, which is my aim.

I finally cracked it! Turns out I was wrong in my last post: I had tried tag**=**EdTest but not tag:EdTest, which turned out to be the right answer!
