We design, build, document and integrate APIs — payment gateways, ERPs, CRMs, logistics partners and your own services — so your systems stop needing a human to copy data between them.
Whether you need an API built, an existing one connected, or a broken integration diagnosed.
Purpose-built REST or GraphQL APIs for your product — versioned, authenticated, rate-limited and documented from the first endpoint.
The part most teams underestimate. We do the whole flow — checkout, signature verification, webhooks, refunds and settlement reconciliation.
Connecting your systems to the tools your business already pays for, with sync that survives outages on either side.
That system nobody wants to touch. We put a clean API in front of it so new software can talk to it safely.
Event delivery you can rely on — signed payloads, idempotency keys, exponential backoff and a replay console.
An existing API that worries you? We test it the way an attacker would and give you a prioritised fix list.
A payment webhook arriving twice, a courier API timing out mid-request, an ERP going down for maintenance — these are not edge cases, they are Tuesday. We build every integration assuming the other side will misbehave, so a bad response becomes a queued retry instead of a lost order and an angry customer.
The same event delivered twice produces one result, never a double charge or duplicate order.
Failed calls queue and retry on a schedule instead of vanishing into a log file.
Every request, response and retry is logged and searchable when you need to prove what happened.
Failure-rate monitoring that pages us when an integration starts degrading.
You should never have to read our source code to use our API. Each project ships with an OpenAPI specification, a Postman collection, working request examples and a sandbox environment your team can hit safely.
If it has a documented API, we have probably wired it into something. If it does not, we have written the adapter.
We document what moves between which systems, how often, and what must happen when one of them is unavailable.
The API contract — endpoints, payloads, error codes — is written and approved before implementation, so both sides can build in parallel.
Development runs entirely on provider sandboxes with test credentials. No live money or production data is touched.
We deliberately break things: timeouts, duplicate webhooks, malformed payloads, expired tokens — and verify the system recovers.
Staged rollout with live monitoring, alerting on failure rates, and documentation handed to your team.
A standard checkout integration with webhooks and refunds typically takes 5 to 10 working days including sandbox testing. Multi-gateway routing, split settlements or subscription billing take longer. The gateway’s own KYC and activation process is usually the slower half — we help you prepare that paperwork.
Often, yes. Depending on the system we can work with its database directly, use file-based exchange on a schedule, or build a small middleware service that exposes a clean API on top. We assess feasibility before quoting.
You do. The source code, the OpenAPI specification and the deployment configuration are all handed over. We do not host your business logic on infrastructure you cannot access.
Every integration ships with monitoring and alerting. Under a support retainer, we are notified of failures automatically and fix them — usually before you hear about it from a customer. Issues caused by our code are always fixed at no charge.
Yes. We run an OWASP API Top 10 review covering authentication, authorisation, injection, rate limiting and data exposure, and deliver a written report ranked by severity with concrete remediation steps.
Certainly. We do consulting engagements — API design review, an integration architecture plan, or pairing with your developers to get a stuck integration over the line.
Tell us what needs to connect to what. We’ll map the integration, flag the pitfalls, and quote it before you commit.
