FAQs
APIs & Integrations, answered
What is the difference between REST and GraphQL for our use case?+
REST is simpler and better for straightforward CRUD APIs. GraphQL wins when clients need flexibility in what data they fetch, when there are many client types (web, mobile, integrations), or when nested data fetching would require many REST round-trips. We help you pick the right one during design.
Can you integrate with Salesforce, HubSpot, SAP, or Zoho?+
Yes. All of these have public APIs and we have shipped integrations with each. Complex two-way syncs with conflict resolution, real-time webhooks, and bulk data migrations are all standard scope.
Do you handle API versioning and deprecation?+
Yes. Every API we ship has an explicit versioning strategy from day one (URL versioning or header versioning), sunset policies for old versions, and deprecation notices to consumers. Breaking changes never happen silently.
What documentation format do you use?+
OpenAPI (Swagger) for REST APIs, self-documenting SDL for GraphQL. Both come with an auto-generated interactive documentation site, code samples in multiple languages, and Postman or Insomnia collections.
How do you handle rate limiting and abuse protection?+
Rate limiting per API key, per IP, and per endpoint using Redis-backed sliding windows. Quotas for tiered plans, request signing for webhook security, and WAF integration for anomaly detection all come standard.
Can you build webhook infrastructure?+
Yes. Webhook delivery with retries, exponential backoff, signature verification (HMAC), delivery status tracking, and consumer-facing management UI. Reliable webhooks are harder than they look, and we get them right.
What about authentication and authorisation?+
OAuth2 for third-party access, JWT for internal service-to-service, API keys for simple integrations. Custom auth (mTLS, SAML) is available when compliance requires it.
Do you provide monitoring and observability?+
Yes. Structured logging, distributed tracing (OpenTelemetry), metrics (Prometheus / DataDog / New Relic), and per-endpoint SLA dashboards are part of every API build.
