An issue occurred when attempting to use the Mailgun REST API from an Angular 6 application. The error message states that the 'from' parameter is missing

I am encountering an error that states the 'from' parameter is missing in the body. Can you help me troubleshoot why this issue is happening?

export class EmailService {
constructor(private http: HttpClient) {}

sendMailgunMessage() {
const options = {
  headers: new HttpHeaders({
    'Content-Type': 'application/x-www-form-urlencoded'
  })
};

const body = {
  username: 'api',
  password: 'key-xxx',
  from: '<<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="254d4049494a654455550b5d5d5d0b46a48">[email protected]</a>>',
  to: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ea929292aa92c4898587">[email protected]</a>',
  subject: 'Subject text',
  text: 'Body text',
  multipart: true
};

return this.http.post('https://api.mailgun.net/v3/app.xxx.com/messages', body, options);
}
}

Upon subscribing to the sendMailgunMessage function, I receive a browser error: HttpErrorResponse {headers: HttpHeaders, status: 400, statusText: "BAD REQUEST"...error : {message: "'from' parameter is missing"}

To ensure privacy, I have replaced sensitive information with xxx. I have also attempted to include the API key in the URL, but still encountered the same 'from' parameter error.

  1. One of the best ways to test your API is by using POSTMAN. You can create an instance of your function and then use 'GET' in POSTMAN to check the results. It's also helpful to try using 'POST' to see if it works properly.
  2. Make sure to check for any other errors that may arise, such as missing parameters. If you encounter this issue, it could mean that no data was actually passed when posting.
