Handling web service response - JSON element present

I'm working with the new UPS Street Level Address Validation API. We've used the old one for years, but it is reaching end of life.

The new REST API is returning a JSON response that contains the following:

"ValidAddressIndicator": "string",
"AmbiguousAddressIndicator": "string",
"NoCandidatesIndicator": "string",

The documentation is lacking... but with the testing I've done it seems like one of the 3 elements will be present (the "string" is always empty).

From the Documentation:

ValidAddressIndicator string <= 1 Indicates query found a valid match.
AmbiguousAddressIndicator string <= 1 Indicates query could not find exact match. Candidate list follows.
NoCandidatesIndicator string <= 1 No Candidate found.

I know I can add "num_ValidAddressIndicator", "num_AmbiguousAddressIndicator", etc. Then check the value to see if the element was sent.

Just curious if there's another way that I've not considered.

TIA,
Greg
