Hello,

 

I am implementing a system based on Business Rules that use the RESTMessageV2 API to make requests to an external service. This system will be potentially doing a high number of requests. Is there any rate limit to outbound REST API requests?

 

Thanks,

Hello @jmlooper ,

I do not think we have a limit for requesting the API calls. You can have numerous API calls as per your requirement.

Hello @jmlooper ,

As far as i know there is no such thing  in ServiceNow which sets the limit rate . System will control it automatically for you.Normally it is just considered as a transaction any REST message  hit will consider it as a transaction 

 

ServiceNow has an approach called semaphore to control the rate how many requests it can handle at the same time. Once the concurrent jobs exceed the number of semaphore then system will put them in a queue and pick up once any semaphore is ready again. You don't need to control it by yourself.

 

Hope this helps 

Mark the answer correct if this helps you 

Thanks
