Can't query anything with GraphQL

[russellbird]

I'm trying to query and update data in our Shopify store via GraphQL.  I can query the required objects such as Customers with the REST API, but I can't do this with GraphQL.  I've executed my basic query in GraphiQL on a demo store successfully, so I know the syntax I'm sending through is correct, but I always get a 404 Not Found response. 

I'm led to believe that there could be a problem with the store itself, but Shopify Support can't seem to help me in regard.  I only want to use GraphQL because it is more efficient to achieve what I'm after and because I don't seem to be able to update MetaFields via REST, although I can query them in REST (not in GraphQL).  Since REST and GraphQL share scopes for Developed Apps, I'm lost as to why I can't query any data using GraphQL.

If anyone has any ideas, I'd appreciate it.

Hi @russellbird 

can you screenshot your Graphql query by any tools like Postman or Insomnia?

Hi,

I'm sending:

{

"query": "query getCustomer($id: ID!) { customer(id: $id) { id email firstName lastName createdAt updatedAt } }",

"variables": {

"id": "gid://shopify/Customer/XXXXXXXXXXXXXXX"

}

}

I've removed the Customer Record ID from the above. 

I'm sending a POST request to /admin/api/2025-04/graphql.json with the X-Shopify-Access-Token header set to my key.  My understanding is that this should behave the same as a GET request to admin/api/2024-10/customers/XXXXXXXXXXXX.json, which works. On the POST request to graphql I get 404 returned.

for Post request, did you accept the scope for your API?
