Zabbix 2.0 API - Item exists but is not readable

[andybon]

I am trying to use the API to read the value of an item from the zabbix server. Using the item.exists() method returns True, but item.isreadable() is returning False. I am logging into the server (via the API) as the default admin user (which works), and I have gone into the administration GUI and changed the 'zabbix administrators' group to have read-write permissions for all defined monitoring groups. Are there any other possibilities for why this is not working?

Thanks...

Could you post the requests you're sending when calling item.exists and item.isreadable?

Here are the requests/responses. I included the login portion:

Item.isreadable only allows to check whether items are readable by item ID. To check if an item is readable by it's key and host use the item.get method.

See the manual for more info:
