A practitioner's guide to securing webhooks and third-party integrations, treating a webhook as an inverted trust surface: an inbound endpoint the organisation exposes so an external party can push data into it. You will implement correct signature verification and avoid the mistakes that quietly defeat it, build replay defence through idempotency and freshness checking, validate payloads against a strict schema, govern a third-party integration marketplace across its full lifecycle, treat outbound webhook delivery to customers with the same rigor as inbound receipt, and build the monitoring and response readiness a webhook endpoint needs but often does not get.
Nothing. Every course, exam, and certificate on the catalog is free — including retakes. All you need is a free Safeguard account.
None. The flagship course, Safeguard Certified Practitioner, is a beginner-level course — basic familiarity with how software is built helps, but every exam question is answerable from the lessons themselves.
You can retake it after a 24-hour cooldown, as many times as you need. Retakes are free, and each attempt draws a fresh random set of questions.
The Safeguard Certified Practitioner credential is valid for 24 months from issue. The expiry date is printed on the certificate and shown live on its public verification page. Renewing means passing the current exam again.
