Integrations we build most often
Website to CRM
Enquiries, quotes and sign-ups flow straight into HubSpot, Salesforce, Zoho or Agrin CRM with source tracking, deduplication and owner assignment.
Payments and billing
Stripe and PayPal checkout, subscriptions, invoicing, refunds and webhooks handled correctly, including the failure cases most sites ignore.
Accounting sync
Orders and invoices posted to Xero or QuickBooks with the right tax codes, so month-end is a report, not a reconciliation.
Email, SMS and notifications
Transactional email via SendGrid or Postmark, SMS via Twilio, Slack and Teams alerts for the events your team needs to act on.
Shipping and fulfilment
Live carrier rates, label generation and tracking updates from Royal Mail, DHL, UPS, FedEx and 3PL warehouses.
Your own public API
REST or GraphQL APIs with keys, OAuth, rate limits, versioning and documentation for partners and mobile apps.
How we make integrations reliable
- Every call is logged with request, response and timing, so problems are diagnosed in minutes rather than guessed at.
- Retries and queues: if a provider is down, work waits in a queue and completes later instead of silently failing.
- Idempotency: a payment or an order is never created twice because a network hiccup repeated a request.
- Webhook verification: incoming events are signature-checked so nobody can forge a "paid" notification.
- Secrets management: API keys live in environment configuration, rotated on a schedule, never in the code.
- Monitoring: failure rates and latency are watched under your maintenance plan, with alerts to us before your customers notice.
How an integration project runs
- Map the dataWhich fields move where, in which direction, on what trigger, and who owns the record when both systems disagree.
- Prototype against sandboxesEvery provider has a test environment. We prove the flow there first.
- Build with error handlingQueues, retries, logging and alerts are part of the scope, not extras.
- Test with real edge casesRefunds, duplicates, timeouts, expired tokens and partial failures, all rehearsed before launch.
- Launch and monitorHosted on our infrastructure with dashboards for volume and failure rate.
Frequently asked questions
What is an API integration, in plain terms?
It is a connection that lets two systems exchange data automatically: your website sending a new enquiry into HubSpot, your store posting invoices into Xero, your app charging a card through Stripe. Instead of retyping or exporting spreadsheets, the systems talk to each other.
Which systems can you connect?
Anything with an API. Regular ones for our clients: Stripe, PayPal, HubSpot, Salesforce, Zoho, Xero, QuickBooks, Mailchimp, SendGrid, Twilio, Google Workspace, Microsoft 365, Zapier, shipping carriers and government or industry portals.
Can you build an API for our own product?
Yes. We design and document REST or GraphQL APIs with authentication, rate limiting, versioning and a developer reference, so partners and mobile apps can build on your platform.
What happens when a third-party API changes?
Integrations are monitored, and breaking changes are handled under your maintenance plan. We log every call, so when a provider changes behaviour we see it before your customers do.
How much does an integration cost?
A single, well-documented integration such as form-to-CRM or store-to-accounting is a small fixed-price job. Multi-system workflows with data mapping and error handling are quoted after a short discovery.
Which systems should be talking?
Name the two systems and what should move between them. We will scope it and quote a fixed price.
