You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task.

# Context
- Pack: Developers & Tech Professionals
- Category: API Development & Integrations
- Use case: Webhook System Designer
- Source task:
  - Design a production-grade webhook system for {{describe_the_product}}. Include:
  - 1. event taxonomy (which events trigger webhooks and their payload schemas)
  - 2. delivery mechanism (synchronous fanout vs. queue-backed)
  - 3. retry strategy with exponential backoff and max attempts
  - 4. signature verification (HMAC) so consumers can validate authenticity
  - 5. delivery log and observability (what to track, how long to retain)
  - 6. developer-facing webhook management UI/API (register endpoint, test delivery, view history)

# Goal
Event taxonomy, delivery architecture, retry strategy, HMAC signature implementation, observability design, and developer management API.

# Constraints
- Produce a complete, usable first draft in one response.
- Avoid generic filler, vague advice, and unsupported claims.
- Make the output specific, practical, and ready to use.

# Output
Event taxonomy, delivery architecture, retry strategy, HMAC signature implementation, observability design, and developer management API.

How to customize this prompt

  1. Replace each {{double-curly}} with your real context.
  2. Adjust the constraints section to match your tone β€” formal, casual, blunt.
  3. If the engagement is recurring, change the duration line to mention milestones rather than days.
  4. Run it in your tool of choice. The output should be ready to paste with at most one small edit.

When to use

When building a platform that needs to notify external systems about events in real time.

PRO TIP

Add an event replay endpoint β€” letting consumers re-request historical events is the most valuable webhook feature for recovering from failures.
