What is a homemade Google Apps Script alternative I can host? I don't know what this kind of app(?) is called.
Specifically, I use a Google Apps Script to receive webhooks from Quickbooks, immediately make the script do API requests to Quickbooks about the webhook event, then that data is parsed into JSON and sent to Facebook through their API.
I hope this question isn't too general. I know I need to write it in something like .NET, Java, NodeJS and host it somewhere. I know it will need an HTTPS address for the redirect URI. I don't know if it's possible or best practice or not to make that the webhook url too. I could host it on Heroku or Digital Ocean maybe? Is this called a RESTful API? A specific type of REST API or is that not what I need to build?
I want to use something else because Google Apps Script seems to only allow the receiving of 20 webhooks a day.
