If you publish listings to portals, required-field validation is the highest ROI control you can implement.
Start here:
The scalable pattern: required fields live with the portal mapping
Required fields are not universal. They depend on the portal.
So the pattern is:
- mapping defines field sources (source paths)
- mapping defines required fields
- publish job validates each listing against the required list
That makes "portal changed requirements" a mapping update, not a full export rewrite.
Per-listing failure messages save hours
If a listing fails validation, the system should say:
- which fields are missing
- on which listing
Without that, teams guess and reupload repeatedly.
Partial success is normal operations
Real portfolios have incomplete listings at any moment.
A robust publish job should:
- publish the valid listings
- fail the invalid listings
- show a summary (published vs failed)
Blocking the entire feed due to a few incomplete listings is an operations anti-pattern.
Store feed outputs (with checksums)
If you store the generated feed output:
- you can debug portal rejections
- you can prove what was generated and when
- you can compare outputs across runs
Checksums make integrity auditable.
