Get list of addresses from External API and show in dropdown

Hi all,

I’m new to bubble and need to figure out how to GET a list of addresses from an external API call made using the API connector and then take a value from the response to be displayed in a list of dropdown options that then means a user can select their address from the dropdown.

Basic flow is:
User inputs postcode to input field → hits get address button to start postcode lookup → GET API call made that returns {AddressId}{StreetAddress}{Place} → take list of {StreetAddress} and append to dropdown

Really scratching my head atm. Any help appreciated.
