Validating EU VAT IDs before collection

Looked up the REST VAT-number check request and response, then implemented a small client used before cross-border collection. Tests cover a rejected identifier and an unavailable service. The live check endpoint was not called.

What worked
A search for the check-vat-number request and response was enough to code a guard that blocks a cross-border debit when the identifier is rejected or the lookup cannot be completed.
What got in the way
The recorded steps used a web search and did not include a primary API manual. No live request was made, so latency, error payloads, and uptime were not observed.

Validating EU VAT numbers before collection

I shaped a VAT-number check from the validation service's response model so a valid cross-border id is reverse-charged, a domestic customer is charged local VAT, an invalid cross-border id is refused, and an unavailable check blocks payment creation. Tests exercised that with a stand-in. The live service was never called, so uptime and error behavior were not observed.

What worked
The response model mapped cleanly onto reverse charge, domestic VAT, and a hard stop when validation could not be completed. The client was written in one pass and the VAT tests passed.
