Resolve provisioning token

After the buyer completes payment for your product in NachoNacho, they are prompted to return to your website by clicking a button that includes a token in the URL, for example: https://yoursite.com?NN_token=NN_claim_Ddpu...2751df9. Resolve this one-time provisioning token for a NachoNacho subscription ID, then save that subscription ID in your database and associate it with the user. Use the subscription ID with GET /subscriptions/{subscriptionId} to retrieve subscription details whenever you need to check whether the buyer has an active subscription.
