Stop copying the same order between systems.
A team copies confirmed orders into its operations tool. Fields differ between systems, updates arrive out of order, and duplicate records are hard to resolve.
The integration needs to define which system owns each value, validate incoming data, and make delivery failures visible to someone who can act on them.
Define the contract, then test the handoff.
The exact scope follows the business need. Work of this kind can take shape through these stages.
- 01
Map the systems and data
Check supported APIs, authentication, rate limits, field definitions, and access requirements. Agree on the source of truth.
- 02
Define the contract
Document required fields, identifiers, update rules, validation, and the expected behavior for missing or invalid data.
- 03
Build the handoff
Implement authentication, data transformation, duplicate protection, retries, and an appropriate processing mechanism.
- 04
Test the exceptions
Exercise delayed events, expired access, malformed records, and downstream outages. Verify that errors can be investigated and recovered.
One order, one dependable handoff.
The example carries a confirmed order into an operations queue.
Receive
An authenticated order event supplies an event identifier, customer reference, and line items.
Validate
The integration checks required fields, maps values, and recognizes events it has already processed.
Deliver
The destination receives a valid record. Failed attempts enter a visible retry or review path.
Data ownership and visible failures.
Explicit ownership of data
Define which system can change each field and how conflicting updates are handled before enabling synchronization.
Observable failures
Record useful event context without unnecessary sensitive data, and agree on alerting, recovery, and who operates the integration.
Connections with a documented operating path.
Deliverables and ownership are agreed in the engagement. For this kind of work, they can include:
- 01
Working system connections
The agreed API endpoints, event handlers, field mappings, and authentication setup.
- 02
Contract and integration tests
Representative success and failure cases that check both sides of the handoff.
- 03
An operating guide
Configuration, credentials ownership, monitoring, and recovery instructions.
