Calling Zapier trigger from Django Code
David here, from the Zapier Platform team. The easiest way to do this is to have the form submit against your server and use a library like requests to POST to Zapier. This way, you don't have to worry about CORS or revealing the hook url to your users. 
Hope that makes sense. ​Let me know if you've got any other questions!
Is there any way I can call the "Zapier trigger" from my Django Code,
Basically, I am having a Django form where the user will enter several email-id and when the user clicks on send button then I want to send this form data to Zapier in order to do the next action like writing in google spreadsheet or sending email to everyone.
