How to invoke GraphQL API in script to query tables

[IronPotato]

Hi All, 

I’m trying to implement GraphQL into project to basically replace GlideRecord queries with GraphQL gueries to retrieve table data. 

I have GraphQL API, resolver and mapping and I’m able to test it via GraphQL Explorer but how to make use of it in script include? How can I actually invoke it?

Any help would be appreciated.

Thanks

GraphQL is normally being called from client side. However, if you want to call it from a script include, you "potentially" could setup a Rest Message and post your GQL to your instance "/api/now/graphql" endpoint. Please note that I have not tested this but it's an option.

Hope that help.

try { 
 var r = new sn_ws.RESTMessageV2('YOUR_REST_MESSAGE', 'REST_MESSAGE_METHOD');
 var response = r.execute();
 var responseBody = response.getBody();
 var httpStatus = response.getStatusCode();
}
catch(ex) {
 var message = ex.message;
}
