Event Webhook Python Code Example

Parse Webhook

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:

from flask import Flask, request
import simplejson
app = Flask(__name__)

@app.route('/parse', methods=['POST'])
def sendgrid_parser():
  # Consume the entire email
  envelope = simplejson.loads(request.form.get('envelope'))

  # Get some header information
  to_address = envelope['to'][0]
  from_address = envelope['from']

  # Now, onto the body
  text = request.form.get('text')
  html = request.form.get('html')
  subject = request.form.get('subject')

  # Process the attachements, if any
  num_attachments = int(request.form.get('attachments', 0))
  attachments = []
  if num_attachments > 0:
    for num in range(1, (num_attachments + 1)):
      attachment = request.files.get(('attachment%d' % num))
      # attachment will have all the parameters expected in a Flask file upload

  return "OK"
