[API] connected

Integrations that don't break on Tuesday

Reliable connections between your systems and theirs.

A made-up checkout asks an address lookup service 'What is the address for this postcode?' and gets the address back, so the customer doesn't have to type it. Payment, text and order-shipped asks follow the same pattern.
A made-up example.

What an API Is, in Plain Terms

An API is the way one piece of software asks another for something: “take this payment”, “send this text”, “what is the address for this postcode”, “has this order shipped”. Almost every modern service offers one. Used well, they let your systems work together without anyone copying information between screens.

We connect your website or system to the services you rely on, and build APIs for your own systems so others can connect to them safely.

Common Integrations

  • Payments — card payments and PayPal, matched to orders
  • Messaging — emails and text messages sent from your system
  • Identity and logins — secure sign-in for staff and customers
  • Data lookups — addresses, company details, maps and more

How We Build Robust Integrations

  • Authentication and security — keys kept safe, access limited to what’s needed
  • Rate limit awareness — staying within what the other service allows
  • Retry and backoff — a failed call tried again sensibly, not a hundred times a second
  • Alerts — a connection that stops working reports it, rather than failing silently

Third-party APIs change. We design integrations to adapt.

Three timelines of a failed connection: failing silently with nobody told, retrying a hundred times a second, and our way, with retries spaced further apart and then an alert that the payments connection has stopped working.
A made-up example.

Who It Suits and What It Costs

Businesses whose website, shop or system needs to talk to another service, and organisations that want partners or suppliers to connect to them. Each integration is quoted on the services involved, and we tell you the price before we start. Related: data feeds for scheduled file exchanges, legacy integration for older systems.

Common Questions

What if the other company changes their API?

They usually give notice. Integrations are built to report a failed connection rather than fail silently, so a change shows up quickly and can be put right.

Can you give our customers or partners access to our data?

Yes, through an API with its own keys and limits, so they see only what they should.

Is it secure?

We keep credentials out of code, use encrypted connections and give each connection the least access it needs.
