Undocumented endpoints
New integrators reverse-engineer behavior from support tickets instead of a spec.

About Our API Practice
An API Engineering Partner
Not an endpoint factory.
ShubhDigi builds APIs as products: contracts that are documented before they are shipped, authentication that scales from a handful of internal callers to hundreds of partners, and versioning that lets you evolve without breaking integrators.
We work with product, platform, and integration teams to model resources and operations around real client needs—mobile apps, partner systems, internal microservices—rather than exposing database tables as endpoints.
From contract design through implementation, hardening, and monitoring, you get one accountable engineering team that documents decisions, ships against a spec, and leaves you with an API your developers and partners can actually trust.
Contract before code
Resource models and operations are specified and reviewed before implementation starts.
Auth as a design constraint
Authentication and scoped authorization are modeled from day one, not retrofitted.
Stability for integrators
Versioning and deprecation policies so partner code does not break without notice.
Observable by default
Logging, tracing, and usage metrics wired in so issues surface before partners complain.
Contract-first API systems
Design the contract · Then build to it
Ad-hoc endpoint sprawl
Undocumented routes, inconsistent auth, and breaking changes shipped without warning.
Platform engineering
Contracts, versioning, documentation, and monitoring built for real integrators.
API delivery cycle
Discover → design contract → build → harden → document → monitor
API Friction Points
Integrations stall when
APIs are improvised.
Many teams ship endpoints fast—then hit walls on auth gaps, breaking changes, and partners who cannot self-serve integration.
Breaking changes without warning
Field renames and removed routes silently break partner integrations in production.
Inconsistent authentication
Mixed auth schemes across endpoints confuse integrators and widen the attack surface.
No rate limiting or quotas
A single runaway client can degrade the API for every other consumer.
Fragile partner onboarding
Without sandboxes and clear docs, every new partner needs hands-on engineering support.
Blind production behavior
Without tracing and usage metrics, diagnosing partner-reported issues takes days.
API Service Menu
Capabilities that take APIs
from prototype to platform.
Full-stack API engineering—contract design, implementation, security, and developer experience—scoped to your integration needs.
REST API Development
Resource-oriented REST APIs with consistent conventions, pagination, filtering, and error formats.
GraphQL API Development
Typed schemas, resolvers, and query cost controls for flexible client-driven data fetching.
Authentication & Authorization
OAuth2, API keys, JWTs, and scoped permissions matched to your integrator trust levels.
Versioning & Deprecation
Version strategy, changelogs, and sunset policies so integrators upgrade on their schedule.
Developer Docs & Portals
OpenAPI-generated references, quickstarts, sandboxes, and SDK snippets that cut support load.
Webhooks & Event APIs
Reliable event delivery with retries, signatures, and replay for asynchronous integrations.
API Gateway & Rate Limiting
Centralized routing, throttling, quotas, and request validation in front of your services.
Legacy API Modernization
Wrap or replace brittle legacy interfaces with modern, documented, secure contracts.
API Shapes
API patterns matched
to who is calling.
Internal, partner, and public APIs carry different trust and stability requirements—select the pattern that fits your consumers.

How We Build APIs
A path from contract to
trusted production platform.
Eight steps with clear durations—contracts reviewed early, sandboxes ready before launch, monitoring live at go-live.
STEP 01
API Discovery
Identify consumers, data owners, and integration patterns that shape resource design.
STEP 02
Contract & Schema Design
Define resources, operations, and schemas in OpenAPI or GraphQL SDL before code is written.
STEP 03
Auth & Security Model
Design authentication flows, scopes, and rate limits appropriate to each consumer tier.
STEP 04
Implementation Sprints
Build endpoints or resolvers against the reviewed contract with automated contract tests.
STEP 05
Docs, SDKs & Sandbox
Generate reference docs, quickstarts, and a sandbox environment for integrator testing.
STEP 06
Load & Security Testing
Rate-limit validation, penetration checks, and load tests before opening to real traffic.
STEP 07
Launch & Partner Onboarding
Staged rollout to partners with support playbooks, monitoring dashboards, and status pages.
STEP 08
Monitoring & Evolution
Usage analytics, versioned enhancements, and deprecation cycles managed with integrators.

Platform Capabilities
What production APIs
need under the hood.
Twelve capabilities that keep APIs stable, secure, and pleasant for every class of integrator.
01Contracts
OpenAPI / GraphQL SDL contracts
Machine-readable specs that generate docs, mocks, and client SDKs automatically.
02Security
Scoped OAuth2 & API keys
Granular scopes and key rotation so partners get least-privilege access by default.
03Reliability
Rate limiting & quotas
Per-consumer throttles that protect shared infrastructure from noisy clients.
04Reliability
Idempotency handling
Safe retries for payment and order-critical endpoints without duplicate side effects.
05Stability
Semantic versioning
Predictable version bumps and deprecation windows integrators can plan around.
06Contracts
Consistent error contracts
Structured error codes and messages so client apps can handle failures gracefully.
07Integration
Signed webhooks
HMAC-signed event payloads with retries and dead-letter handling for reliability.
08Architecture
API gateway routing
Centralized entrypoint for auth, throttling, and request validation across services.
09Observability
Request tracing & logging
Correlate requests across services to debug partner-reported issues quickly.
10Developer Experience
Generated SDKs & clients
Typed client libraries generated from the contract for faster partner integration.
11Developer Experience
Sandbox environments
Isolated test environments with seed data so integrators build without touching production.
12Operations
Usage analytics & billing hooks
Per-key usage metrics that feed dashboards, alerts, and metered billing where relevant.
API Domains We Build
Integrations shaped by how
each ecosystem connects.
Integrator expectations differ by domain—we encode them into contracts, auth, and documentation.
Why ShubhDigi API
API engineering with
integrator-first discipline.
You get more than endpoints—you get contracts, security, and documentation that partners can build on with confidence.
Contract-first delivery
Specs are written and reviewed before implementation, catching design flaws early and cheaply.
Security modeled explicitly
Auth, scopes, and rate limits are design decisions—not defaults left to chance.
Stability integrators can plan around
Versioning and deprecation policies documented so partner code does not break silently.
Documentation as a deliverable
OpenAPI references, quickstarts, and sandboxes ship alongside the API—not as an afterthought.
India advantage, global integration norms
Strong engineering capacity with communication practices that work for distributed partner teams.
Connected platform services
SaaS, CMS, CRM, and cloud expertise when your API needs to plug into a bigger product roadmap.
