Webhook retries eventually stop. Your recovery plan needs to work after that point.
A useful sandbox drill is to make the endpoint unavailable, complete a test payment, then restore it and follow your provider's recovery procedure.
Can you find the payment your app missed? Can you repair the missing access without granting it twice?
Compare provider payment records with local orders and access records. Make discrepancies visible and repairs safe to repeat.
An empty webhook error log won't reveal a payment your application never received.
