You can request to change your plan at any time by emailing api-support@greatschools.org. If you request a change before the end of your current billing cycle, you will not receive a refund for the payment of your current plan. The new invoice created will not be prorated, and you will start a new billing cycle. You will be able to use your existing API key, as it will now be associated with your new plan. You may also request for the change to take place at the end of your current billing cycle and we will schedule the change to take place on the appropriate day. Please allow 1-3 business days for the update to take place.
