Your business tools should work together seamlessly. We design, build and maintain API integrations that connect your CRM, ERP, payment provider, marketing platforms and custom systems into one unified data ecosystem — eliminating manual work and data silos.
An API (Application Programming Interface) is a set of rules that allows different software systems to communicate with each other. API integration is the process of connecting those systems so they share data automatically — without manual export-import, copy-paste or re-keying.
Modern businesses run on dozens of tools: a CRM for sales, an ERP for operations, an e-commerce platform for orders, a payment gateway for transactions, a marketing platform for campaigns. Without integration, these systems operate in silos — meaning duplicated data entry, human errors, slow processes and a fragmented view of your business.
We build robust, well-documented integrations using REST APIs, GraphQL, webhooks, OAuth 2.0 and custom middleware. Whether you need two systems to talk or a full data mesh connecting ten platforms, we architect and deliver integrations that are reliable, maintainable and built to last.
From out-of-the-box connectors to fully bespoke middleware, we integrate any platform your business relies on.
Connect Salesforce, HubSpot, Pipedrive and Zoho CRM to your website, marketing tools and operational systems. Synchronise contacts, deals, activities and custom objects in real time.
Integrate Stripe, PayPal, GoCardless, Worldpay and Braintree to automate payment collection, subscription billing, refunds and reconciliation across your platforms.
Connect Royal Mail, DPD, Evri, DHL and FedEx APIs to automate label generation, tracking updates, delivery notifications and returns management — directly from your order management system.
Sync customer and behavioural data with Mailchimp, Klaviyo, ActiveCampaign and HubSpot Marketing Hub. Trigger personalised campaigns from real-time events in your other systems.
Integrate Xero, QuickBooks, Sage and FreeAgent to automate invoicing, payment reconciliation, VAT reporting and financial data synchronisation across your business tools.
Connect Shopify, WooCommerce, Magento and BigCommerce to your ERP, WMS, 3PL and marketing stack. Automate order sync, inventory updates and customer data flows.
Integrate Twilio for SMS, SendGrid and Mailgun for email, Slack for internal alerts, and WhatsApp Business API for customer messaging — all triggered by events across your platforms.
Connect SAP, Microsoft Dynamics 365, Oracle NetSuite and Sage 200 to your e-commerce, CRM and supply chain tools. Synchronise inventory, purchase orders, financials and production data.
We engineer integrations that are robust, observable and easy to maintain — not fragile scripts that break at the first API change.
We map every data flow your business needs — which systems send data, which receive it, what triggers events and what transformation logic is required. We document the full integration specification before writing a line of code.
We review the API documentation for every platform involved, identify rate limits, authentication methods, webhook capabilities and data schemas. We then design the optimal architecture — direct API-to-API, middleware layer or event bus — based on your requirements.
We implement OAuth 2.0, API key management and token refresh flows securely. All credentials are stored in environment variables or secrets managers — never in code. We follow OWASP API security best practices throughout.
We write the integration logic, data transformation functions, field mapping and business rules. REST endpoints, GraphQL queries, webhook handlers and queue processors are all built to handle edge cases, null values and unexpected API responses gracefully.
Full integration testing in sandbox environments before any live data is touched. We test happy paths, error scenarios, rate limit handling, duplicate prevention and idempotency — ensuring the integration behaves correctly under all conditions.
Every integration ships with logging, error alerting and a dashboard so you can see data flowing in real time. We offer ongoing management retainers to handle API version upgrades, platform changes and new requirements as your business evolves.
These are some of the most impactful integrations we build for UK businesses. If yours is not listed, get in touch — we have likely done it.
Shopify/WooCommerce orders automatically flow to your 3PL or warehouse system, trigger shipping label generation via Royal Mail or DPD, and update tracking in your CRM.
Website enquiries, chatbot conversations and paid ad leads are captured, scored and routed automatically to the right sales rep in HubSpot or Salesforce — with no manual data entry.
Stock levels update in real time across Shopify, Amazon, eBay and your ERP whenever a sale is made — preventing overselling and manual stock counts.
When a deal is marked as won in your CRM, a Xero or QuickBooks invoice is automatically created, sent to the client and tracked for payment — without anyone touching a spreadsheet.
We work at the protocol level and across every major integration platform.
Every integration project is fully documented and delivered with the tools you need to understand, maintain and expand it.
Order management, inventory sync, shipping automation and marketplace integrations that scale with your sales volume.
CRM-to-ERP data flows, lead routing, automated quoting and document generation that eliminate manual steps from your sales cycle.
Secure patient data flows between booking systems, EHRs and CRMs — built with GDPR compliance and data encryption at every layer.
Payment gateway integrations, open banking API connections and automated reconciliation flows — all built to FCA-compliant security standards.

A single, well-documented API integration typically takes 1–3 weeks from kickoff to production deployment. Multi-system integrations involving custom middleware or complex data transformation logic take 4–8 weeks. Enterprise data mesh projects are scoped individually. We always provide a timeline in our project proposal, and we communicate proactively if anything changes.
We encounter this regularly. Our team is experienced at reverse-engineering poorly documented APIs, working with vendor support teams to fill gaps and building resilient integrations that handle undocumented edge cases gracefully. Where an API is genuinely too poorly documented or unstable to integrate reliably, we will tell you honestly and propose alternatives such as database-level integrations, file-based transfers or browser automation.
Data security is central to everything we build. All credentials and API keys are stored in secrets managers (AWS Secrets Manager, HashiCorp Vault) — never in source code. Data in transit is always encrypted via TLS 1.2+. We implement the principle of least privilege so integrations only access the data they need. We document all data flows to support your GDPR data processing register and can sign a Data Processing Agreement (DPA) where required.
Yes. For simpler use cases, iPaaS tools like Zapier, Make (formerly Integromat), Boomi or MuleSoft can be the right choice — fast to implement and straightforward to maintain. For high-volume, complex or mission-critical integrations, custom-coded solutions are typically more robust, significantly cheaper at scale and give you full control. We will recommend the right approach for your specific situation during the scoping call.
This is one of the most common integration challenges. We build with defensive programming practices — graceful error handling, alerting on unexpected responses and comprehensive logging — so you know immediately if something breaks rather than finding out days later from missing data. Clients on our Managed Service retainer receive proactive monitoring and we handle API version migrations as part of the monthly fee.
Absolutely. Many of our most impactful integrations connect legacy or bespoke internal systems that lack modern APIs. We can build API wrappers around database layers, implement file-based integrations (SFTP, CSV, EDI), build message queue consumers or develop RESTful API layers on top of existing systems. If your business runs on a custom platform, we will find a way to connect it.
Yes. Our list of named platforms is illustrative, not exhaustive. If a platform offers an API — and almost every modern SaaS tool does — we can integrate with it. We regularly integrate with industry-specific platforms, niche tools and proprietary systems across sectors including healthcare, legal, logistics, manufacturing and financial services. Share your requirements and we will confirm feasibility on our scoping call.
A REST API is a pull-based approach — your system requests data from another system when it needs it. A webhook is push-based — a platform automatically sends data to your system the moment an event occurs (e.g., a payment succeeds, an order is placed). We use both depending on what each platform supports and what your business needs. Webhooks are generally preferred for real-time event-driven integrations; REST polling works well for scheduled data syncs and queries.
