Integrations & Automation

Webhook Integration

Event-driven webhook receivers and emitters with verification, retries, and observability.

Webhook Integration makes event-driven updates trustworthy. We implement signature verification, idempotent handlers, retry-safe processing, and clear dead-letter behavior so partner events become reliable automation fuel instead of mysterious missed updates.

Who it’s for

  • Product teams consuming vendor webhooks
  • Platforms emitting events to customers or partners
  • Ops teams replacing polling with events

Problems we address

  • Webhook endpoints are unauthenticated or unverified
  • Retries create duplicate side effects
  • Failed deliveries disappear without replay options

Expected outcomes

  • Verified receivers with idempotent handlers
  • Queue-backed processing for durability
  • Delivery logs and replay guidance

Architecture

Integration flow

Events move between systems through APIs, queues, and workflow runners.

Source systemWebhook / APIQueueAutomationTarget system

Deliverables

  • Webhook contract documentation
  • Implemented receiver and/or emitter
  • Monitoring for failure rates
  • Replay / dead-letter runbook

Out of scope

  • Guaranteed partner delivery SLAs
  • Public event marketplace product builds unless scoped

Timeline

Typical timeline

1–4 weeks

Timeline depends on scope, access, and dependencies—not a delivery guarantee.

Process

A clear delivery path from discovery through handover and optional support.

  1. 01

    Discovery

    Goals, constraints, success criteria, and current-state review.

  2. 02

    Architecture

    Target design, interfaces, risks, and delivery sequence.

  3. 03

    Implementation

    Incremental build with visible progress and documented decisions.

  4. 04

    Testing

    Functional checks, failure paths, and acceptance criteria validation.

  5. 05

    Deployment

    Controlled release to staging and production with rollback paths.

  6. 06

    Handover

    Runbooks, access notes, and operator/admin walkthrough.

  7. 07

    Support

    Optional hypercare window or retainer continuity after go-live.

FAQ

Yes. We can implement a poller that emits internal events, or document the trade-offs if webhooks are unavailable.
