Info

We recommend using our official Python SDK, our client library with full documentation, when integrating with SendGrid's Inbound Parse Webhook(link takes you to an external page).

In this example, we want to parse all emails at address@email.sendgrid.biz and post the parsed email to http://sendgrid.biz/parse. In this example we will be using Python the Flask framework.

Given this scenario, the following are the parameters you would set at the Parse API settings page(link takes you to an external page):

Hostname: email.sendgrid.biz
URL: http://sendgrid.biz/parse

To test this scenario, we sent an email to example@example.com and created the following code:

1
from flask import Flask, request

2
import simplejson

3
app = Flask(__name__)

4


5
@app.route('/parse', methods=['POST'])

6
def sendgrid_parser():

7
  # Consume the entire email

8
  envelope = simplejson.loads(request.form.get('envelope'))

9


10
  # Get some header information

11
  to_address = envelope['to'][0]

12
  from_address = envelope['from']

13


14
  # Now, onto the body

15
  text = request.form.get('text')

16
  html = request.form.get('html')

17
  subject = request.form.get('subject')

18


19
  # Process the attachements, if any

20
  num_attachments = int(request.form.get('attachments', 0))

21
  attachments = []

22
  if num_attachments > 0:

23
    for num in range(1, (num_attachments + 1)):

24
      attachment = request.files.get(('attachment%d' % num))

25
      attachments.append(attachment.read())

26
      # attachment will have all the parameters expected in a Flask file upload

27


28
  return "OK"

29


30
if __name__ == '__main__':

31
    app.run(debug=True)
