WSO2 APIM: Calling service APIs through cURL gives no response - wso2

Question

I'm using APIM 4.1.0. I am following this and another tutorial to create an API through publisher service API. After generating the access token I use the below command but there is no response. No error code even. Are these URLs correct?
curl -k -H "Authorization: Bearer <access-token>" -H "Content-Type: application/json" -X POST -d #data.json https://127.0.0.1:9443/api/am/publisher/v2/apis
data.json file contains:

You have to use v3 version as follows.
curl -k -H "Authorization: Bearer <access-token>" -H "Content-Type: application/json" -X POST -d #data.json https://127.0.0.1:9443/api/am/publisher/v3/apis
