Hi @arthursa1 , as this is a persisted query, variables should be sent as the part of the URL and not as a body.

Following is the documentation for the same: https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/headless/graphql-api/persisted-queries#query-variables

The Method used in your Postman request is of type 'POST', whereas Persisted queries can work only with GET method.

Hence all parameters have to be a part of URL, separated by ';' or %3b.

Example: append the %3bpaths=%7B"_expressions":[%7B"value":"/content/site1"%7D,%7B"value":"/content/site2"%7D,%7B"value":"/content/site3"%7D] in the URL
