How to use Mailgun API for email sending in Ionic?

I’m trying to set up email sending in my Ionic app without using the email composer. I’ve been looking into the Mailgun API, but I’m running into some issues. I’ve updated my imports to use HttpClient and HttpHeaders from @angular/common/http since the old Http from @angular/http is deprecated. Here’s what my updated send method looks like:

send() {
  const endpoint = 'https://api.example.com/v3/messages';
  const body = '[email protected]&[email protected]&subject=Test&text=Hello world';
  const headers = { 'Authorization': 'Basic ' + this.apiKey };

  this.http.post(endpoint, body, { headers }).subscribe(
    response => console.log('Success:', response),
    error => console.error('Error:', error)
  );
}

I’ve also added HttpClientModule to my app.module.ts file. However, when I try sending an email, I receive a 401 Unauthorized error. I’ve verified my API key and domain, but I still face this issue. Has anyone successfully integrated Mailgun with Ionic? Any advice or alternative code examples would be greatly appreciated. Thanks!

I’ve been through this exact headache with Mailgun and Ionic. One thing that tripped me up was the endpoint URL. Make sure you’re using the correct one for your region. If you’re in the EU, it should be ‘https://api.eu.mailgun.net/v3/YOUR_DOMAIN/messages’ instead of the US one.

Also, don’t forget to URL encode your parameters. I had issues until I did this:

const params = new URLSearchParams();
params.set('from', '[email protected]');
params.set('to', '[email protected]');
params.set('subject', 'Test');
params.set('text', 'Hello world');

this.http.post(endpoint, params.toString(), { headers }).subscribe(...)

This approach worked like a charm for me. Hope it helps you too!

I’ve successfully integrated Mailgun with Ionic in a recent project. One crucial step often overlooked is proper API key encoding. Ensure you’re using Base64 encoding for your API key in the Authorization header:

const headers = new HttpHeaders({
‘Authorization’: 'Basic ’ + btoa(‘api:’ + YOUR_API_KEY),
‘Content-Type’: ‘application/x-www-form-urlencoded’
});

Additionally, consider using environment variables to store sensitive information like API keys. This practice enhances security and makes deployment across different environments smoother.

Lastly, don’t forget to handle potential CORS issues. You might need to configure your Ionic app and Mailgun account to allow cross-origin requests. This step is often necessary when working with external APIs in mobile applications.

hey mate, i had similar issues. try using content-type header too. like this:

const headers = new HttpHeaders({
‘Authorization’: 'Basic ’ + btoa(‘api:’ + YOUR_API_KEY),
‘Content-Type’: ‘application/x-www-form-urlencoded’
});

also make sure ur using the correct mailgun domain. good luck!
