Publishable or secret key: which goes where?
The publishable key goes in the browser: it reads what is published and takes bookings. The secret key reads customers and payments, so it stays on a server.

Glossary
The words these pages use, said once and plainly
Every term, with what it means hereNumbers come from the code
A limit or a retention window is read from the setting that enforces it, so a guide cannot go on quoting last year's figure.
Dated, and sourced
Every guide shows the day it was last checked, and links the pages of other companies it describes.
No stories we cannot show
No invented customers, results or quotes. Where an example is needed, it says it is one.
