A lot of SalesForce objects have a field "Description", and they are usually accessible through the API.

So does the object CampaignMember but for some reason it is NOT accessible through the API.

Can anyone tell me why that is?

I need to have control over it from Perl.

Salesforce IDs are of course unique, and they remain stable for a given object during that object's lifecycle.

We intend to use the ID to keep an external database synchronizd with data from Salesforce.

If an object is deleted in Salesforce (and also deleted from the recycle), that object will no longer be synchronized but it will be kept in our external database for historical reasons.

Is there any possibility that the Salesforce ID at some time will be recycled and suddenly represent a totally different object?
