Event Webhook Python Code Example

Parse Webhook

(information)

Info

We recommend using our official Python SDK, our client library with full documentation, when integrating with SendGrid's Inbound Parse Webhook.

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:

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:

1from flask import Flask, request
2import simplejson
3app = Flask(__name__)
4
5@app.route('/parse', methods=['POST'])
6def 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
30if __name__ == '__main__':
31    app.run(debug=True)
