I'm trying to send an email with an attached file with the Mailgun API using requests.post.
In their documentation they alert that you must use multipart/form-data encoding when sending attachments, I'm trying this:
import requests
MAILGUN_URL = 'https://api.mailgun.net/v3/sandbox4f...'
MAILGUN_KEY = 'key-f16f497...'
def mailgun(file_url):
"""Send an email using MailGun"""
f = open(file_url, 'rb')
r = requests.post(
MAILGUN_URL,
auth=("api", MAILGUN_KEY),
data={
"subject": "My subject",
"from": "[email protected]",
"to": "[email protected]",
"text": "The text",
"html": "The<br>html",
"attachment": f
},
headers={'Content-type': 'multipart/form-data;'},
)
f.close()
return r
mailgun("/tmp/my-file.xlsx")
I've defined the header to be sure that the content type is multipart/form-data, but when I run the code, I get a 400 status with reason: Bad Request
What's wrong? I need be sure that i'm using multipart/form-data and I'm using correctly the attachment parameter

You need to use the files keyword argument. Here is the documentation in requests.
And an example from the Mailgun documentation:
def send_complex_message():
return requests.post(
"https://api.mailgun.net/v3/YOUR_DOMAIN_NAME/messages",
auth=("api", "YOUR_API_KEY"),
files=[("attachment", open("files/test.jpg")),
("attachment", open("files/test.txt"))],
data={"from": "Excited User <YOU@YOUR_DOMAIN_NAME>",
"to": "[email protected]",
"cc": "[email protected]",
"bcc": "[email protected]",
"subject": "Hello",
"text": "Testing some Mailgun awesomness!",
"html": "<html>HTML version of the body</html>"})
So modify your POST to:
r = requests.post(
MAILGUN_URL,
auth=("api", MAILGUN_KEY),
files = [("attachment", f)],
data={
"subject": "My subject",
"from": "[email protected]",
"to": "[email protected]",
"text": "The text",
"html": "The<br>html"
},
headers={'Content-type': 'multipart/form-data;'},
)
This should work fine for you.
