Mail Gun Email Not Working In Flask On Google App Engine

Question

I'm trying to send an automated mailgun email from my flask app on Google App Engine. It works fine when I run locally. However, even though it runs without error the email is not being sent.

Here is the code:

def send_simple_message(text):
    url = 'https://api.mailgun.net/v3/{}/messages'.format('')
    auth = ('api', '3822ba6d2b1ad202e83a4322a80c7600-87cdd773-683e02b1')
    data = {
        'from': 'Mailgun User <mailgun@{}>'.format('sandboxf04ggge3c1dc36e527c92f3a967e7f7c.mailgun.org'),
        'to': 'example@gmail.com',
        'subject': 'Simple Mailgun Example',
        'text': text
    }

    response = requests.post(url, auth=auth, data=data)
    response.raise_for_status()

Any thoughts?

Any errors in the logs that you can include? – Dustin Ingram Jun 06 '19 at 23:02 — Dustin Ingram, Jun 06 '19 at 23:02

I am not familiar with the malign api, but looking at the example in the documentation, I think you forgot to add your domain to the url:

def send_simple_message(text):
    url = 'https://api.mailgun.net/v3/{}/messages'.format('sandboxf04ggge3c1dc36e527c92f3a967e7f7c.mailgun.org')
    auth = ('api', '3822ba6d2b1ad202e83a4322a80c7600-87cdd773-683e02b1')
    data = {
        'from': 'Mailgun User <mailgun@{}>'.format('sandboxf04ggge3c1dc36e527c92f3a967e7f7c.mailgun.org'),
        'to': 'example@gmail.com',
        'subject': 'Simple Mailgun Example',
        'text': text
    }

response = requests.post(url, auth=auth, data=data)
response.raise_for_status()
