How it works
Calculate reliability needs
Sensitivity, retries, ordering and version policy determine delivery-readiness.
Draft the envelope
The output includes stable identifiers, timestamps, version and tenant context without copying unnecessary records.
Frequently asked questions
What makes a good webhook event name?
Use a stable business fact in past tense, such as subscription.activated, rather than an internal method name.
Should the full record be sent in every payload?
Not automatically. Send the minimum useful snapshot and stable identifiers; highly sensitive or rapidly changing data may be safer to retrieve through an authenticated API.
Can webhook delivery be exactly once?
Consumers should generally assume at-least-once delivery and handle duplicates idempotently using a stable event ID.
How should breaking changes be handled?
Prefer additive changes. For unavoidable breaks, version the contract, document the difference and give consumers a migration window.
