Why wont heroku let me use my own sendgrid account?

Question

Why won't heroku let users use their own sendgrid accounts?

I installed sendgrid addon to heroku with following command:

heroku addons:create sendgrid:starter

and when i log into my dashboard heroku creates me a starter account. How do i use my own sendgrid account that I already have and tested on my app?

Answer 1

Heroku won't prevent you from using your own sendgrid account. You can set your own config vars to setup the credentials of any account you wish.

For example:

heroku config:set SENDGRID_ID=abcd SENDGRID_TOKEN=efgh

Those two config vars will then be available to your app as environment variables.
Provisioning the add-on will only attach a new sendgrid account to your heroku account, and automatically set the config vars. But nothing prevents you from doing that yourself.
