What’s an x-Credit?
x-Credits are a currency used to meter Support Tickets or request other types of assistance available under a Sencha support plan as described in Table 1 above. For example, a Support Ticket uses 10 x-Credits per incident. Telephone Support uses 50 x-Credits per hour with a 25 x-Credit minimum. The available number of x-Credits depends on the Support Plan you purchase, as described in Table 1. Premium Support forums are available 24×7×365 and do not use any x-Credits.
The process for requesting assistance using x-Credits is described in our support process letter that is sent to our customers’ primary support contacts when they purchase a support plan. This process is also described in our Support and Maintenance agreement.
How many x-Credits are required for Sencha Space support?
Support subscriptions for Space do not consume x-Credits. You can use Premium Support features for Sencha Space as needed without impacting your x-Credit balance.
