REST API not supported

Posted on by davallen Microsoft Employee

I am exploring creating PCF controls. One requirement is to connect to data sources outside of Dynamics/CDS. Is this capability supported by the framework? Will I need to handle my own authentication flow through adal.js accordingly?

You can call external rest api's (provided of cause you avoid any CORS related issue) and we discussed connecting to Nasa photo a day api the week before last (when I get a spare hour I will create a component that does just that and publish it on Github.

Unfortunately you will need to handle any authentication flow yourself and you really need a typescript library to do that (look at adal-ts for a typescript ADAL library).

Hi @davallen ,
We have used "cross-fetch" to do the api call.

add cross-fetch
npm install cross-fetch

sample code
private async makeRequest() {
let searchName = this._searchNameElement.value;
console.log(searchName);
fetch('https://api.github.com/users/' + searchName , {
method: "GET"
})
.then(res => {
if (res.status >= 400) {
throw new Error("Bad response from server");
}
return res.json();
})
.then(data => {
console.log("Data");
console.log(data);
let resp = JSON.stringify(data, null, '');
let j = JSON.parse(resp);
this._fullNamelableElement.innerHTML = j['name'];
})
.catch(err => {
console.error(err);
});
}

Hi @BenJBauer ,
Interesting to know when we use PCF components to call an api what would be the source of the request. We also had some issue with CORS. It worked when we use a wildcard.

I used node-rest-client and it worked like a charm.

We do not support the external data sources 1st class like canvas powerApps. You can evaluate embedded canvas app for data fetch scenarios or use the auth library. Please consider token handling , mobile shims especially don't have a way to handle these. Server side plugin and azure keyvalult are other potential options.
