With Foursquare's API Endpoint Venues.search:
If the categoryId parameter is coupled with the ll parameter, it returns the expected response; filtered venues by category.
However, if I use categoryId parameter with the near parameter, the response does not have the venues filtered.
Sample:
Request with llreturns filtered venues by categoryId.
Request with near returns non-filtered venues by categoryId.
Thoughts?
The issue here is secondary category matching. The results look like they're not filtered correctly because the response from search only shows the primary category. The venues actually match on a secondary category, which you can see by looking at the venue detail response.
