Connect your tools, automate your workflows and make your systems talk to each other
We build custom APIs and integrate third-party services — payment gateways, WhatsApp automation, CRMs, ERPs, SMS platforms, analytics tools and more. Stop copying data between systems manually and let your software do the work.
How APIs connect your systems
Popular integrations
Your tools don't talk to each other — and your team is paying for it
Most businesses run on a collection of disconnected tools. Data gets copied manually, mistakes get made, and hours are wasted every week on work that software should be doing automatically.
Without API Integration
Payment confirmed in Paystack — someone manually updates the CRM, the spreadsheet and the WhatsApp group. Three steps, three chances for human error.
Payment lands, but the customer gets no confirmation for hours because someone has to manually send it. Bad experience, unnecessary support queries.
The same customer exists three times in three systems with slightly different details. No one knows which is correct. Reports are unreliable.
You can't see what's happening across sales, payments, fulfilment and support in one place — because the data lives in different systems with no connection.
With DigitalX API Integration
Payment confirmed → CRM updated, invoice generated, WhatsApp message sent, spreadsheet logged. All in under 3 seconds, zero human involvement.
The moment a payment is verified, the customer gets a WhatsApp confirmation with their order details — automatically, every time, no manual work.
One integration keeps your CRM, payment system and app database in sync — same data everywhere, no duplicates, reports you can trust.
All your tools feeding into one dashboard — payments, orders, support tickets, fulfilment status — visible in real time without switching between systems.
What we integrate and connect
We've built integrations across every major category of business software — Nigerian-specific and international.
Payment Gateways
Full payment integration — card, bank transfer, USSD, mobile money, recurring billing, webhook verification, refunds and reconciliation.
Messaging & Communication
WhatsApp Business API, SMS gateways, email platforms and in-app chat — for customer notifications, support automation and transactional messaging.
CRM & Sales Tools
Sync contacts, deals, notes and activity between your app and your CRM — keeping sales teams up to date automatically without manual entry.
Identity & KYC Verification
Nigerian identity verification for regulated products — BVN lookup, NIN verification, CAC business registration checks and international KYC providers.
Google & Productivity APIs
Google Maps, Places, Calendar, Sheets, Drive, Gmail, Analytics, Search Console — automate reports, sync data to Sheets, embed maps and more.
ERP & Accounting Systems
Connect your app to accounting and ERP systems — sync orders, invoices, payments and inventory automatically between your software and your books.
Logistics & Delivery APIs
Shipping rate calculation, tracking number generation, delivery status webhooks and last-mile delivery APIs for Nigerian and African logistics providers.
Analytics & Data Platforms
Send events to analytics platforms, build data pipelines between systems and push business data into BI tools for reporting and dashboards.
AI & Automation APIs
OpenAI, Claude and Gemini API integrations for intelligent features — chatbots, document processing, content generation, classification and data extraction.
We don't just plug in an API — we design the integration properly so it doesn't break.
Most API integrations fail in production — not because the code was wrong at launch but because no one thought about error handling, webhook retries, rate limiting, token expiry or what happens when the third-party service goes down. We build integrations that handle real-world conditions: failures, timeouts, duplicate events and edge cases that only appear under load.
- Error handling & retry logic
- Webhook signature verification
- Rate limit handling
- Idempotent operations
- Full API documentation (Swagger)
- Logging & monitoring
Outcome
Systems that stay connected, data that stays in sync and workflows that run automatically — without your team doing it manually.
API development & integration services
From building an API from scratch to connecting your existing tools — we cover every API scenario.
Custom API Development
RESTful and GraphQL APIs built from scratch — well-architected, versioned, authenticated and fully documented. Built for the apps, teams and third parties that need to consume them.
Payment Gateway Integration
Complete Paystack and Flutterwave integration — payment initialisation, webhook verification, recurring charges, split payments, refunds and reconciliation reports. Including USSD and bank transfer flows.
WhatsApp Business API
Automated WhatsApp messaging via the official Business API — order confirmations, payment receipts, delivery updates, OTP delivery, appointment reminders and customer support chatbots.
Webhook Systems & Event Pipelines
Reliable webhook ingestion and processing — signature verification, idempotency handling, retry queues, failure alerting and event logging. Built to handle production volumes without data loss.
Third-Party System Sync
Two-way data sync between your app and external platforms — CRMs, ERPs, accounting tools, Google Sheets, project management tools — so data is always consistent everywhere.
API Documentation & Developer Portal
Swagger/OpenAPI documentation, interactive API explorer, authentication guides, code samples in multiple languages and developer onboarding materials — for teams or third parties consuming your API.
What a production-grade API integration actually requires
Most integrations work in testing. These are what make them work reliably in production, under real load, with real edge cases.
Authentication & Security
API keys, OAuth 2.0, JWT tokens, webhook signature verification and request validation — so only authorised callers can access your API and fake webhook events are rejected.
Retry Logic & Idempotency
Webhooks can be delivered more than once. Our integrations detect and deduplicate duplicate events — so a payment webhook arriving twice doesn't charge the customer twice.
Rate Limit Handling
Every third-party API has rate limits. We implement request queuing, exponential backoff and intelligent caching so your integration never exceeds limits or drops requests.
Logging & Audit Trail
Every API call, webhook event and integration action is logged with timestamps, payloads and outcomes — so you can debug issues, audit activity and trace any transaction.
Error Handling & Alerting
All integration failures are caught, categorised and handled gracefully — with automatic alerting to your team for critical failures and a dead-letter queue for failed events that need reprocessing.
Full Documentation
Every API we build or integrate is documented in Swagger/OpenAPI — endpoints, parameters, request/response schemas, error codes and authentication methods — so your team or other developers can work with it without asking us.
