Hi @AvinashV0407 , can you share the postman request? error it shows in IDE? Even how you configured the json call request?

With JSON Call you have two options:

• Register a Generic Server connection and provide credentials there. And then reference that server in Url Resource section of JSON Call step
   
• You can set URL in the Url section of JSON Call. In that case you have to manually supply properly encoded Authorization header. E.g. to use basic authentication, you have to provide Base64 encoded user and password. (wiki)

Example of generic server configuration

That’s a Kafka server (you can notice Implementation field), Generic Server looks like this

Thanks @AKislyakov and @fbarretto for the info shared.

I have tried creating connection and tried the way that I have mentioned in the above screenshots  too.

But unable to execute the input template query/mutation. Please let me know if I missed anything.

Hi @AvinashV0407, can you please share the whole plan with JSON call (you can remove Authorization details and obscure URL) and the error details. 

Meanwhile, I noticed that you set Content-Type:application/json in JSON Call, whereas Postman uses Content-Type:application/graphql, so please check that you properly transformed the query for the JSON Call (check graphql docs for the details)
