Week 5 of 8
EIBs and integrations
Workday gives you three ways to integrate: packaged connectors, the Enterprise Interface Builder (EIB) for no-code loads and extracts, and Workday Studio for more complex integrations that Workday hosts. Benefits carriers, 401(k) recordkeepers, banks, time clocks and identity providers all sit on the other end.
Two things catch teams out. A refresh copies production configuration into non-production, so check that every outbound integration points at a test endpoint before anyone runs it. And integration testing needs the vendor: book their test windows early.
This week: inventory every integration and give it a test endpoint
- List every integration and direction: type (EIB, connector, Studio), vendor, data, schedule, file format, Workday owner and vendor contact.
- Record the non-production endpoint for each outbound integration and whether it must be re-pointed after a refresh.
- Plan positive, negative and change-detection tests for each. An outbound file that sends everyone when only one worker changed is a defect.
- Log every EIB load with rows in, rows loaded and rows in error. Agree an error threshold before the first mock load.
- An integration is ready only when it has passed in the final end-to-end cycle with the vendor confirming the result.
