Hi Tim, You can request multiple priorities by adding on the same field with a different value. /attask/api/v5.0/project/search?priority=1&priority=2 You can also use a modifier to grab all priorities greater / less than... /attask/api/v5.0/project/search?priority=2&priority_Mod=lte The greater than/less than etc. modifiers can be found on Filter and Condition Modifiers within the support site. Thanks!
