Portals reject listings for predictable reasons. The fix is not "try again". The fix is a deterministic feed pipeline.
If you want feed generation and validation in the product:
Checklist: make required fields explicit
Before you generate a feed, define required fields per portal.
Common examples:
- listing code
- title
- listing type (rent/sale)
- price and currency
- location (city)
Then validate before generation. If a listing is missing required fields, fail it explicitly.
Checklist: escape XML correctly
If you generate XML:
- escape
&,<,>, quotes - treat descriptions as untrusted text
- keep encoding consistent (UTF-8)
Most portal XML failures are not "business logic". They are invalid XML output.
Checklist: keep listing codes stable
Stable listing codes are how portals and internal teams reconcile data.
If listing codes drift:
- duplicates appear
- updates become new listings
- portal reconciliation becomes manual work
Checklist: publish as a job (with artifacts)
If publishing is a job, you can:
- track per-listing outcomes (published/failed)
- allow partial success
- store the generated feed output
- compute a checksum for integrity
That is what makes portal publishing operational instead of ad-hoc.
