Connecting systems also means designing for failure
Three decisions that make an integration easier to operate and maintain.
Agree on what the data means
Define which system owns each field and how statuses, dates and identifiers are represented. Document these decisions with the team.
Design what happens when something fails
Decide how to record errors, when to retry and how to avoid processing the same operation twice. Include a way to review pending cases.
Make the journey visible
Use a tracking identifier and useful error messages. The team should be able to locate an operation without exposing sensitive information in logs.
