Get Access Token in Ionic

Question

Through the command prompt I get an access token.

curl -v https://api.sandbox.paypal.com/v1/oauth2/token \ -H "Accept: application/json" \ -H "Accept-Language: pt_BR" \ -u "my-client_id:my-client_secret" \ -d "grant_type=client_credentials"

In the project I use this token and get a json.

Service.ts

getPayment() {
let token = 'A21AAGsiyUhk3ntiu7MMtkvc_aTKaXyWHdfKRrMV0qqNyPQ1ZzxXrT2oxGGdz8wLVcgZzmwgQ8r1mdMLprw0vsB374AI8D2AA';
const httpOptions = {
  headers: new HttpHeaders().set("Authorization", [`Bearer ${token}`]).set("Content-Type", "application/json")
}
return this.http.get("https://api.sandbox.paypal.com/v1/payments/payment/PAY-1826783671569693VLQ2IYVQ", httpOptions)
  .pipe(
    catchError(this.handleError)
  );
}

Component.

  this.authService.getPayment().subscribe((response) => {
   console.log('abcde', JSON.stringify(response))
 });

However, I need to generate this Token automatically, but I don’t know how to send my Client_id and Secret by parameter. Any help?

Answer 1

In case anyone ever needs it, here’s the solution I got:

var request = require('request');

request.post({
    uri: "https://api.sandbox.paypal.com/v1/oauth2/token",
    headers: {
        "Accept": "application/json",
        "Accept-Language": "en_US",
        "content-type": "application/json"
    },
    auth: {
        'user': 'SEU CLIENT ID',
        'pass': 'SEU CLIENT SECRET',
        // 'sendImmediately': false
    },
    form: {
        "grant_type": "client_credentials"
    }
}, function(error, response, body) {
    console.log(body);
});

if require is not accepted:

npm i @types/node
and add:

"types": [
    "node"
],
"typeRoots": [
    "node_modules/@types"
]

in the archive tsconfig.json
and also: declare var require: any; in its component

Answer 2

pegarToken(){
 const auth = btoa(`${this.clientId}:${this.clientSecret}`);//substitui pelo seu id e secret
 return `Bearer ${auth}`;
}


getPayment() {
let token = this.pegarToken();
const httpOptions = {
  headers: new HttpHeaders().set("Authorization", token).set("Content-Type", "application/json")
}
return this.http.get("https://api.sandbox.paypal.com/v1/payments/payment/PAY-1826783671569693VLQ2IYVQ", httpOptions)
  .pipe(
    catchError(this.handleError)
  );
}
