Hello,
I wrote on a provider script this call ‘https://www.paypal.com/it/cgi-bin/webscr’, but I got an error with paypal that block the request. Is it possible to solve this problem?
Thanks in advance

Hi,
I don’t know if this could help you, but when I make an Http request I add this header:

  getWsHeader() {
    let tempToken;
    const content_type = 'application/json';
    tempToken = this.getToken();
    const headers = {
      'Content-Type': content_type,
      'Accept': 'plain/text',
      'Access-Control-Allow-Origin': '*',
      'Access-Control-Allow-Methods': 'POST, GET, OPTIONS, PUT',
      'Access-Control-Allow-Headers': 'Authorization, Origin, Content-Type, X-CSRF-Token',
      'auth': tempToken
    };
    console.log(headers);
    return  new HttpHeaders(headers);
  }

so the request becomes:

    return this.httpClient.post(commandUrl,
      commandBody,
      {headers: this.getWsHeader(), responseType: 'text'});

Hello,
Thanks for suggestion. We add your code, but we got a different error.
Have you an idea for that error?
Thanks in avance
Here is my code:
paypal(){ //

var data2 = "cmd=_cart&upload=1&business=pag@xxx.com";

console.log(data2);
var config = {
headers : {
‘Content-Type’: ‘application/json’,
‘Accept’: ‘plain/text’,
‘Access-Control-Allow-Origin’: ‘*’,
‘Access-Control-Allow-Methods’: ‘POST, GET, OPTIONS, PUT’,
‘Access-Control-Allow-Headers’: ‘Authorization, Origin, Content-Type, X-CSRF-Token’,
//‘auth’: tempToken
}
};

    return Observable.create(observer => {

this.http.post(‘https://www.paypal.com/it/cgi-bin/webscr’,data2,config).subscribe(data =>
{

console.log(‘rispostada4D’,data);//you can format the response from your server
observer.next(data );//and then return data
observer.complete();
});
});

}
