Few months ago we had to eliminate the
Parties Parties.ListPartiesByTags(IEnumerable<int> tagIDs, int pagingOffset = 0) method from our SDK, because Highrise API didn’t support the underlying REST call anymore. We were very happy when we realized that Highrise can filter contacts by multiple tags (see: http://help.37signals.com/highrise/questions/57-how-do-i-search-by-multiple-tags), so we were hoping we could enable again the involved method.
When you look at the URI in the browser when you searching by multiple tags, you may see something similar: https://somedomain.highrisehq.com/tags/1963039,1973268,1969549,1984865,1690134,1963033
And not a rocket science to get the xml representation of this call: https://somedomain.highrisehq.com/tags/1963039,1973268,1969549,1984865,1690134,1963033.xml
The only problem is Highrise limits the number of combined tags… boom. Only the first 5 parameters matters and the followings will be ignored. Of course we will create another ListPartiesByTags() upon this behavior.
We are proud to say that WLH supports contact search by unlimited number of tags.
