Overview
Webhooks notify other systems when something happens — a payment succeeded, an order shipped, a document was signed. Reliable webhook delivery is harder than it looks: signatures, retries with backoff, idempotency, ordering, replay, failure visibility and endpoint management. We build webhook infrastructure for platforms sending events, and robust handlers for systems receiving them.
Common use cases
- Platform event deliveryNotifying customers and partners of events.
- Payment and fintech eventsCritical financial events with strong delivery guarantees.
- Integration triggersDriving automation in customer systems.
- Receiving third-party webhooksRobust handlers for provider events.
Quick answers
Webhook Development at a glance
The essentials in brief. Every project is scoped individually — ask us for specifics.
- What is webhook development?
- Reliable webhook systems: event delivery with signing, retries, ordering, replay and self-service endpoint management.
- Who is it for?
- Typically startups building a first product, scale-ups extending a platform, and enterprises replacing or modernising internal software.
- What does Shivacha provide?
- Event catalogue
- Signing & verification
- Retries & backoff
- Replay & logs
- Endpoint management
- Idempotent handlers
- Which technologies are used?
- OpenAPI, GraphQL, gRPC, WebSockets, OAuth 2.0 & OIDC, Apache Kafka — chosen to fit your stack and constraints.
- How does the process work?
- Contract design → Security model → Implementation → Testing → Developer experience.
- What affects the cost?
- Number of user roles and core workflows
- Platforms (web, iOS, Android)
- Third-party integrations
- Design depth and accessibility targets
- Data migration from existing systems
- Performance, scale and uptime requirements
- How long does it take?
- An MVP typically takes 8–14 weeks; larger platforms are delivered in phases with a usable release every few weeks.

Documented event types and payload schemas.
Signing & verification
HMAC signatures and timestamp checks.
Retries & backoff
Automatic redelivery with exponential backoff.
Replay & logs
Delivery logs and manual replay for customers.
Endpoint management
Self-service subscription configuration.
Idempotent handlers
Safe processing of duplicate deliveries.
Architecture
Engineered right from day one
The layers we typically design for API, integration & distributed systems, adapted to your stack and partners.
- Versioning strategyBackward-compatible evolution and clear deprecation policies.
- IdempotencySafe retries for operations with side effects.
- ObservabilityTracing across services and per-consumer usage metrics.
- SecurityOAuth 2.0 scopes, input validation and rate limiting on every endpoint.
Delivery
How an engagement runs
- 1
Contract design
API specifications (OpenAPI, GraphQL schema, protobuf) agreed before implementation.
- 2
Security model
Authentication, authorisation scopes and threat model defined up front.
- 3
Implementation
Services, gateway configuration and SDKs built against the contract.
- 4
Testing
Contract, load and security tests automated in CI.
- 5
Developer experience
Documentation, sandboxes and change logs for API consumers.
Security
Security built into delivery
Controls we apply by default on this kind of work — not a separate phase at the end.
Secure SDLC
Code review, dependency scanning and secrets kept out of source control.
Authentication
Proven identity providers, MFA and least-privilege roles.
OWASP coverage
Protection against common web and API vulnerabilities, verified in testing.
Backups & recovery
Automated backups with tested restore procedures.

Frequently asked questions
Are webhooks guaranteed to be delivered?
Webhooks provide at-least-once delivery with retries; consumers should handle duplicates idempotently and can reconcile via APIs.
How are webhooks secured?
With payload signatures, HTTPS-only endpoints, timestamp validation and optional IP allowlisting.
REST, GraphQL or gRPC?
REST is the most interoperable choice for public and partner APIs. GraphQL suits product frontends that aggregate many resources. gRPC suits high-throughput internal service communication. Many platforms use all three in different places.
Do you document APIs?
Yes. We produce machine-readable specifications, human-readable reference docs, guides and examples, and can publish a developer portal.
