Integrations

Connect Your Stack to Anything

We integrate your website, app or internal system with any third-party API — from payment processors and CRMs to AI models and logistics platforms. If it has an API, we connect it.

What's Included

API Integrations — Full Scope

Every integration is built with error handling, logging, retry logic and webhooks — not a fragile copy-paste job.

Payment & Billing APIs

Stripe (payments, subscriptions, Connect marketplace), PayPal, Easypaisa, JazzCash, Razorpay, Square and bank transfer APIs with PCI-compliant flows.

CRM & Marketing APIs

HubSpot, Salesforce, Mailchimp, ActiveCampaign, Klaviyo — two-way sync of contacts, deals, email campaigns and customer lifecycle events.

AI & Machine Learning APIs

OpenAI (GPT-4o, Assistants, embeddings), Anthropic Claude, Google Gemini, Stability AI (images) and HuggingFace model endpoints integrated into your product.

Communication APIs

Twilio (SMS, WhatsApp, voice), SendGrid (transactional email), Vonage, Firebase Cloud Messaging and Slack/Teams bot integrations.

Logistics & Shipping APIs

DHL, FedEx, Royal Mail, ShipStation, EasyPost — real-time shipping rate lookups, label generation, tracking webhooks and customs documentation.

Webhook Architecture

Build → receive → validate → process → retry. We design reliable inbound webhook handlers with signature verification, idempotency and dead-letter queues.

ERP & Accounting APIs

Xero, QuickBooks, Sage, SAP Business One — invoice sync, purchase order automation, bank reconciliation and inventory level webhooks.

Security & Auth APIs

OAuth2, OIDC, SAML2 SSO with Google/Microsoft/Okta, reCAPTCHA v3, fraud detection (Sift, Signifyd) and IP reputation APIs.

How We Work

Our Proven Process

Transparent, milestone-based delivery — you always know what's happening and what's next.

API Audit

Review existing systems, identify data flows, map authentication requirements and agree on error handling and retry strategy.

Specification

Document exactly what data moves where, in which format, how often and who owns each field — before touching a keyboard.

Development

Build integration layer with typed models, error handling, logging, and unit tests covering happy paths and failure modes.

Sandbox Testing

Test every scenario in vendor sandbox environments — failed payments, webhook failures, rate limiting, schema changes.

Monitoring

Set up alerting for failed webhooks, API latency spikes and quota consumption. Runbook for common failure scenarios.

Documentation

Handover docs covering auth rotation, rate limits, data mappings and how to extend the integration for future needs.

FAQ

Frequently Asked Questions

Any API with documentation — REST, GraphQL, SOAP or proprietary SDK. We have integrated 100+ APIs across payments, CRM, logistics, AI, communication, accounting and HR platforms.

Yes. We reverse-engineer vendor APIs regularly using network inspection, vendor support channels and trial-and-error. We always sign an NDA when working with proprietary systems.

We build exponential backoff retry logic, circuit breakers, request queuing and graceful degradation — so your system stays functional even when a third-party API is slow or temporarily unavailable.

Yes. APIs change — vendors release new versions, deprecate endpoints and change authentication requirements. We offer monitoring plans that include proactive updates when vendor APIs change.

Sometimes, yes — through browser automation (Puppeteer), email parsing, file-based integrations (CSV/SFTP) or middleware platforms (Zapier/Make). We will assess feasibility in a free discovery call.
