Loop Back Integration Pattern

The loop back pattern writes the IDs generated by the target system back to the source record. For example, when creating an Account record in Salesfroce from a Customer in Sage, the Salesforce Object ID should be written back to the Customer record.

This is a common integration pattern, not specific to Salesforce, but due to concerns with API usage and the overhead Lookups almost all Salesforce integrations should use the following pattern.
