Rest API Call from Custom Visual

Hi Everyone,

 

I am new to power bi development and trying to achieve below scenario.

I am trying to make a REST API call through the Custom Visual created in javascript. But unable to perform the action successfully.

I can see below error in chrome dev tools console, once my custom visual appears in the report: 

 

Refused to connect to 'https://xxxxxxxxxx/Data.json' because it violates the following Content Security Policy directive: "default-src https://app.powerbi.com data: blob: 'unsafe-inline' 'unsafe-eval'". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.

 

Is it possible to make a restful api within the limits of Custom Visual? or if there's another appropriate method of achieving this?

Thanks,

Zaheer

    Hi,
    You need to specify the RestAPI endpoint inside capabilities.json, Below is the code for your reference : 

    "privileges": [
            {
                "name": "WebAccess",
                "essential": true,
                "parameters": ["http://localhost:44353"]
            },
           {
                "name": "WebAccess",
                "essential": true,
                "parameters": ["http://localhost:8000"]
            }
        ]

      Can a custom visual do an API call and hold the response in memory? does the 30,000 limit apply in that case?
