Do I need to write code to automate PayPal Invoicing?

No. You describe the outcome you want in plain words. HumDay agrees a contract with you, writes the program, and shows you a test run before anything touches your PayPal Invoicing account.

16 of the 22 documented operations change something in PayPal Invoicing, and 6 read from it. HumDay only ever uses the specific operations your approved contract needs.

Is my PayPal Invoicing account safe?

Your credentials are stored encrypted and are never shown in chat, code, or logs. Every run is limited to the operations you explicitly approved, and anything that writes to PayPal Invoicing is held behind that approval.

How automating PayPal Invoicing works

Describe the outcome. Say what you want to happen, in your own words. No node graphs, no field mapping.
Approve the contract. HumDay writes down exactly what it will do, what it will touch, and what it will never do. You approve it before anything is built.
See it proven. The program runs and shows you the result before it is allowed near your live PayPal Invoicing account.
Grant access, then go live. You approve the specific PayPal Invoicing operations it may use — and only those.
