I am using a Google Form to record answers from different friends. Depending on their answers they are going to receive different bills. I want to create a Bash script that...
- Download the answers every 3 minutes
- Check if there are new answers in the past 3 minutes
- Calculate their bill
- Send an email with a paypal invoice.
I am having issue for the point number 4. I have a standard account on Paypal. I understand how I can use the email an invoice
option to directly email an invoice. However, this solution doesn't allow me to
- Send an invoice automatically and directly after the user has answered to the Google Form
- Send an invoice that is a function of answers to the Google Form.
Note that it is important that I can track who paid with an ID number.
What solution do I have? For example, can I produce about 40 types of invoice corresponding to 40 different URLs and then just send the URLs on my email?
