Common Questions tag

Everything you need to know about implementation details and compliance infrastructure.

rocket_launch Implementation

Why is the minimum query length 4 characters?

add

Anything shorter returns too many matches to be useful and triggers a lot of unnecessary load. The minimum is enforced server-side and you’ll get a 400 back if you send fewer than 4 characters.

rocket_launch Implementation

How do I render the results in a SELECT element?

add

Each match has an address_option field with the full address as a single string (e.g. “6 PACKHAM PL CHARNWOOD ACT 2615”), ready to use as the visible option text. Use address_id as the option value so you can resolve it back to a GNAF later.
