WATS Rest API
By using the HTTP Client toolkit in LabVIEW, you can utilize the WATS Rest API to query the WATS Server. For documentation, see the WATS Rest API section.
For Authentication use a security token. See this article on how to create a token: https://virinco.zendesk.com/hc/en-us/articles/207424253-Authentication
The same example also applies for WATS On Prem where https://nn.skywats.com is replaced with your local WATS Server address.
