FastSpring and SaaS

Hi,

is there any sample/manual of setting up fast spring for SaaS business model?especially setting update_expires (date) field on recurring basis?

Marcin

Basically just modify the existing example and use limelm.pkey.setDetails.

This is what I wrote for having automatic subscription renewals with FastSpring:

First off, you have to have two PHP scripts, one that gets run for the initial order and one that gets run when the subscription is renewed.

In my example, I have two plans (Lite and Pro) and I use the same scripts for each FastSpring product and populate some Checkbox custom license field according to the FastSpring product name so I know what features to enable in my app.

I like to store as much information as I can about the order in my LimeLM custom license fields so I try to get every possible FastSpring variable stored.

These are the custom license fields that I created in LimeLM:fastspring_company (String) (Desc: Company name on FastSpring checkout)fastspring_email (String) (Desc: Email on FastSpring checkout)fastspring_name (String) (Desc: Name on FastSpring checkout)fastspring_original_subscription_expiry (Date/Time) (Default Value: + 365 days) (Desc: Original Subscription end date. Set on initial order)fastspring_productName (String) (Desc: FastSpring Product Name that was purchased)fastspring_quantity (Integer) (Desc: Original quantity purchased on FastSpring checkout. This is the number of activations that were purchased. Script generates one product key with 'quantity' activations.)fastspring_reference (String) (Desc: FastSpring Order ID. Initial Order only. Useful for looking up order in FastSpring.)fastspring_subscription (String) (Desc: FastSpring Subscription ID. Consistent between initial order and rebills)fastspring_subscription_renew_count (Integer) (Default Value: 0) (Desc: Auto increments each time the subscription is renewed via FastSpring)fastspring_test (String) (Desc: Whether or not a test credit card was used to create the FastSpring order)is_lite_licese (Checkbox) (Readable in-app) (Desc: If the license has lite functionality. This depends on what plans you have)is_pro_license (Checkbox) (Readable in-app) (Desc: If the license has pro functionality. This depends on what plans you have)notes (String) (Desc: Extra notes about license that you can manually enter)subscription_expiry (Date/Time) (Default Value: + 365 days) (Readable in-app) (Desc: Actual subscription expiry that gets updated on rebills. Use this field in your app to check if subscription is still active.)
