Turbofloat - Fastspring purchase - How many

On integrating our product with fastspring, we can use the below line to post that as a turbofloat key. 'for_tfs' => 'true'

However, how many floating licenses would this key allow for, by default? And, is there a way of automatically linking a survey field from fastspring to change the number of floating keys associated with the license key, so the process is completely automated? Or, any other alternative?

I went through the PHP code, but wasn't able to see this option...

End goal is to have a field, where the customer purchases a key with X number of floating licenses, and in the end, he pays the price multiplied by X dollars.

The web API documentation for limelm.pkey.generate is here. It lists all of the parameters and what they mean.

The FastSpring example code already does what you want:

    'num_keys' => 1,    'num_acts' => $quantity,

This means the TFS will be able to grant "$quantity" floating license leases.

Sam - the 'num_acts' relates to the number of allowed deactivations, correct? What I'm looking for, is the number of simultaneous floating computers.

A TurbFloat Server key can only be activated on a single computer. We've updated the documentation to reflect that setting "num_acts" on TFS keys sets the number of allowed concurrent connections to that TurboFloat Serve instance.

Ah, got it, thanks.
