01Follow the handoff
Begin with a repeated task: copying an enquiry into a customer system, reconciling an order or sending an approval to the next person. Record the trigger, required fields, destination, frequency and exceptions. Establish the current effort and error rate before deciding that automation is the right investment.
A connection can move information without making the underlying process better. Resolve inconsistent field definitions, duplicate customer records and unclear approval responsibilities first. An initial manual review step may be sensible for sensitive or unusual transactions.
02Confirm what each system supports
Check the available API, webhook or supported connector, its authentication method and any plan restrictions. The business should control the relevant accounts and authorise access to only the records needed. Record third-party fees, API limits and dependencies in the scope.
Decide which system is the source of truth. A two-way connection requires conflict rules: if an address changes in both systems, which value wins? A one-way transfer may be easier to operate when only one team needs to edit the data.
03Design for retries and exceptions
A useful integration handles duplicate events, incomplete records and temporary service outages. Agree what can be retried safely and what needs human attention. An order should not be duplicated because a delivery confirmation was delayed. Logs should help diagnose an error without unnecessarily exposing customer details.
Acceptance testing should include an unavailable destination, an expired credential, an invalid field and an event sent twice. Use test accounts and synthetic data where available. Successful transfer of one example is not enough evidence of a reliable workflow.
