API Integration

Connect your systems so data is entered once

We design and build authenticated APIs and integrations between your website, CRM, payment gateway and internal tools, with validation, error handling and logging so a failed sync is visible rather than silent.

  • REST APIs
  • JSON
  • Token-based authentication
  • Payment gateway webhooks
  • SQL Server

How a Project Is Delivered

1

Discover & Specify

Clarify who will use it, what it must connect to, and how you will judge success.

2

Architect & Design

Agree the data model, screens and integrations in writing before production code is written.

3

Milestone Development

Build in agreed milestones, with working builds you can review and approve at each stage.

4

Quality Gate & Handover

Testing, production deployment and handover of source code and documentation as agreed in writing.

Problems This Service Solves

  • The same data typed into several tools
  • Payments or enquiries that do not reach the right system
  • Integrations that fail without anyone noticing

API Integration in practice

Who this suits

Businesses typing the same data into several tools, or whose website enquiries, payments and CRM records do not reach each other reliably.

What you receive

Authenticated REST APIs or integrations between your website, CRM, payment gateway and internal tools, with validation, error handling and logging, so a failed sync is visible and can be corrected rather than lost silently.

How we approach it

We agree which system owns each piece of data, define the contract in writing, and build with token-based authentication and webhook handling where payments are involved. We test failure cases such as duplicate messages and timeouts, not only the happy path.

Frequently asked questions

What can you integrate?

Websites, CRMs, payment gateways and internal tools that expose a documented API. Feasibility is confirmed during scoping.

How do you handle failures?

Requests are validated, errors are logged, and failed calls are retried or surfaced for review instead of being dropped.
