Token scope - Read & write subscription contracts
Rate limit - Global pool (i.e. 50 requests per second per domain)
Note: If nextBillingDateEpoch is within 24 hours of the time the Create Subscription API is called, the first order will be shifted to the next billing cycle instead of being created at the specified date/time. To avoid this, ensure that nextBillingDateEpoch is passed at least 24 hours in the future from the time the API is called.
