I used the following method (https://wit.ai/docs/http/20160526#post--entities-:entity-id-values-link) to add a keyword to a user defined entity, and it worked. However, when I did this to add a keyword to wit/location (one of the built-in entities in wit.ai), it did not work.
How do I add a keyword to wit/location using the http api?
Is there another way I can add keywords to wit/location automatically?
