SendGrid
This prefab will add a logic component to your cloud functions so you can send emails with SendGrid, it will show up in the SendGrid folder among your cloud functions.

Settings
First you must provide a few settings, this is done in the Config part of the Cloud Dashboard. Launch your cloud services dashboard (if you don't have a cloud service you need to create and make it active for the project).

Then find the Config section in the sidebar of your dashboard. You can take a look at the Config node for more details on how config parameters work. Create a parameter for SendGridAPIKey, make sure you make the Master Key Only so it is protected in your cloud service.
