Production subscriptions

Production subscriptions are rate-limited to 480 calls per minute. Please review your contracting details for the number of calls your subscription allows. We do not place a hard limit on your quota, but you may incur overage charges if you surpass your contracted amount.

Sandbox subscriptions

Sandbox subscriptions are rate-limited to 60 calls per minute. This subscription type is only available under certain circumstances written in your contract. Sandbox subscriptions can only be used for development purposes, and they should never be used in a production environment. The sandbox subscriptions have a 1,000 call quota which resets every year.
