How does it work?
Start with as much address context as the user can provide. A street name alone may exist in dozens of cities. Submit the phrase, display candidates with region labels and save the location after the user selects it.
Where can you use this API?
Keep both the original text and the selected result. This preserves an audit trail when an address is corrected later. Do not force a false match when the service finds nothing; allow manual correction.
What should you consider?
Protect API credentials, cache repeated searches and distinguish location matching from official postal deliverability checks.
