API Integration Services
Connect your systems seamlessly with custom REST and GraphQL API development, third-party integrations, payment gateways, and event-driven webhook architectures.
Our API Integration Services
Everything you need to connect your systems and data — reliably and securely
RESTful API Development
Well-documented, standards-compliant REST APIs with authentication, rate limiting, versioning, and comprehensive error handling — built to last.
GraphQL Services
Flexible GraphQL APIs that give clients exactly the data they need — reducing over-fetching, enabling real-time subscriptions, and simplifying frontend development.
Third-party Integrations
Seamless connections to any external service — CRMs, ERPs, analytics platforms, marketing tools, and more — with robust error handling and retry logic.
Payment Gateway Integration
Secure payment processing with Stripe, PayPal, and regional gateways — subscriptions, one-time payments, refunds, and webhook-driven order management.
Social Media APIs
Publish, monitor, and analyse social content across platforms via official APIs — automated posting, comment management, and analytics aggregation.
Custom Webhooks
Event-driven webhook systems that push real-time updates between your systems the moment something changes — reliable, signed, and retryable.

Frequently Asked Questions
Answers to the most common questions about this service.
A single point-to-point API integration (connecting two systems) starts around $2,500–$6,000. Complex integrations involving multiple systems, custom data transformation, error handling, and monitoring range from $10,000–$40,000+. We assess complexity in a free scoping call before quoting.
A straightforward integration between two well-documented APIs takes 1–3 weeks. Multi-system integrations with custom mapping, bi-directional sync, and robust error handling take 4–10 weeks. Timeline depends heavily on the quality of the third-party documentation and sandbox environments.
If it has a public API — yes. We've integrated with hundreds of services including Stripe, Salesforce, HubSpot, Shopify, QuickBooks, Twilio, SendGrid, Google Workspace, Microsoft 365, AWS services, and many more. We can also reverse-engineer private APIs or use browser automation where no API exists.
We version-pin API calls and build with defensive error handling so changes degrade gracefully rather than silently corrupt data. Clients on support plans receive monitoring alerts when integrations fail, and we respond with a fix within 4 business hours.
Yes. We design and build RESTful APIs and GraphQL APIs from scratch — with authentication (JWT, OAuth 2.0), rate limiting, documentation (OpenAPI/Swagger), versioning, and thorough test coverage. A well-designed API is a long-term asset for your business.
Security is built in at every layer: HTTPS-only communication, API key rotation policies, OAuth 2.0 for third-party authorisation, input validation and sanitisation, rate limiting to prevent abuse, and logging of all requests for audit trails. We also conduct security reviews before go-live.
What Clients Say About This Service
Real feedback from businesses that have used this service.
“They built a Python automation layer that synchronises data across seven different APIs in real time. Zero data loss in 6 months of production. The API integration work was equally impressive — they handled edge cases we hadn't even thought of.”
James Kowalski
VP of Technology, DataBridge Inc.
“BitPixel built our entire API layer and cloud infrastructure from scratch. The auto-scaling configuration they set up handled a 10x traffic spike during our product launch without a single incident. Our uptime has been 99.98% since go-live.”
