Hackathons, Template Engine, and I Yamil Asusta July 29, 2014 Technical // SUMMARIES ?> If you haven’t been living under a rock, you probably know that SendGrid released Transactional Templates recently. I’ve been using them for a while, specifically for my API demos. It makes it super simple for me to customize emails for a specific school or crowd on the fly without touching any code. With Transactional Templates I don’t ever touch my code. Here is how my code looks like: import sendgrid import os sg = sendgrid.SendGridClient(os.getenv('SG_USER'), os.getenv('SG_PWD')) mail = sendgrid.Mail(subject='10', firstname.lastname@example.org', html='Happy Hacking!', text='Happy Hacking', email@example.com', from_name='Yamil @elbuo8') mail.add_to('firstname.lastname@example.org') mail.add_filter('templates', 'enable', 1) mail.add_filter('templates', 'template_id', 'fd6ecf80-fc43-46da-80b0-f3e26777b514') sg.send(mail) Now if I want to go to HackRU and give a demo, I don’t have to change anything in my code. I can go to the Templates interface and activate the template that I set up for HackRU. When I send my email, it will look like this: Now, next weekend I’ll probably head on over to hackNY, I just need to activate that template and I’m done. If you notice, the only thing that matters is the ID of the template 🙂 Convenient right? Anyone can start using the Template Engine! If you have any issues or questions, feel free to poke me @elbuo8.
