Think in business events
API integration connects systems through defined interfaces. The useful question is what event should cause what change. A booking confirmation might create a customer record; a shipment update might refresh a tracking screen. Describe that event and result before discussing tools. This keeps the integration tied to an operational need.
Identify the source of truth
If two systems store a customer’s address, decide which one owns it and how corrections travel. Without that agreement, each system can overwrite the other. Document the fields being exchanged, their meaning and the unique identifiers used to match records. A name alone is usually a poor record identifier.
Map the complete lifecycle
Creating a record is only the beginning. Include updates, cancellations, deletions where appropriate and exceptions. For a delivery workflow, ask how an unknown carrier or missing tracking number is represented. Agree how staff can correct an unsuccessful transfer without creating a duplicate or losing the original request.
Ask about access and failure
Confirm what the provider permits, how credentials are managed and whether a test environment exists. Plan for timeouts, unavailable services and usage limits. The website should show a truthful status rather than pretending a failed request succeeded. Define who investigates failed transfers and how they are retried safely.
Request an integration specification
A useful specification contains the trigger, field mapping, direction, ownership, error handling and acceptance tests. For example: “A confirmed booking creates one CRM enquiry with the booking reference; retries do not create additional enquiries.” That sentence is far more useful for estimating work than simply asking for a CRM connection.
