Frequently Asked Questions
Which PayPal endpoint to monitor?
POST /v1/oauth2/token validates auth works. In production, monitor a non-destructive endpoint.
Does PayPal have a status page?
Yes, status.paypal.com. But external monitoring is often faster.
How to distinguish Sandbox from Production?
Sandbox uses api-m.sandbox.paypal.com, Production uses api-m.paypal.com.
Are PayPal webhooks reliable?
Generally yes, but plan for retry on PayPal's side and monitor their reception.
