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 firstname.lastname@example.org 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:
To test this scenario, we sent an email to email@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'] 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)
