Is there a hard limit to the amount of in- and outbound api calls ?

[JG6]

Hello Community,

When making and receiving api calls, does Servicenow impose a hard limit on the *amount* of calls ? For example, a monthly limit which might depend on the subscription.  The more expensive the subscription, the more traffic is allowed, etc... Or are these hard limits ? Or no limits ?

A second question is about the maximum *rate* of api calls. I assume a Servicenow instance will respond with 429's when the rate exceeds a certain maximum. Is there an official ceiling to this rate ? Or maybe, this really depends on the subscription ?

Technically, there is no limit, but depending on the calls and how they are made, you may run into license issues. But that's also ServiceNow handles very smoothly: you just continue making the calls, they just start billing you more. So get in touch with your account rep to get your own specifics.

So there are license limits. Is this something I can lookup ?
