Event Webhook Python Code Example
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))
attachments.append(attachment.read())
# attachment will have all the parameters expected in a Flask file upload
return "OK"
if __name__ == '__main__':
app.run(debug=True)
