Let your systems work together.

Start with the records and events that need to cross a boundary: a new enquiry, a payment update or an approved application. We identify the owning system, required fields and expected timing. This prevents two applications from silently treating themselves as the source of truth.

Documentation, sandbox credentials, account permissions and usage limits shape what can be built. We review these before promising an integration. If a provider offers only exports or a restricted interface, the proposal should explain that limitation and the practical alternatives.

A contract defines request formats, validation, response states and authorisation. It should describe incomplete or invalid requests as well as successful ones. Versioning and change management matter when a mobile app or another team’s application will depend on the interface.

Networks fail and providers may send an event more than once. We design the agreed workflow so retries do not create duplicate payments or records. Monitoring, reconciliation and a clear recovery path help operators distinguish a delayed update from a failed business transaction.

Credentials should be managed on the server and limited to the work they need to perform. Roles and logging must reflect the sensitivity of the data. We agree retention, audit and operational access requirements with the business before connecting private records.

Integration acceptance should include invalid credentials, missing fields, duplicate events, provider downtime and recovery. Production verification is separate from sandbox testing. The handover identifies provider accounts, configuration ownership and the person responsible when either side changes its interface.
