API and webhook integration
When The system has a documented interface and we are allowed to use it.
The straightforward case. We build against the vendor interface, handle authentication and rate limits properly, and treat their downtime as a condition to design for rather than an incident to be surprised by.
Event-driven capture
When The system has no usable API, and modifying it is not an option.
We observe the system non-invasively and turn what it does into structured events. Nothing inside the application changes, which means nothing inside the application breaks. This is the pattern most often described to us as impossible.
Database-level bridging
When The data is reachable but the application layer is not worth integrating against.
Read-safe access, usually against a replica, with change data capture where the volume justifies it. Writes go back through supported paths wherever any exist.
Document and content pipelines
When The information arrives as a PDF, a scan, a spreadsheet or an email.
Intake, extraction, classification and validation — with human review on the cases that warrant it — so unstructured content becomes records the rest of the estate can act on.
Hybrid and on-premise connectivity
When Part of the estate is in a building and cannot be exposed.
Outbound-only connectors and local agents, so an on-premise system participates without becoming internet-facing. No inbound firewall exceptions.
Orchestration across systems
When A single business process spans four applications that have never spoken.
Sequencing, state, compensation when a step fails partway, and a record of the whole transaction rather than six disconnected logs.
