Callouts Are Excluded from Long-Running Request Limit

Every org has a limit on the number of concurrent long-running Apex requests. This limit counts all requests that run for more than 5 seconds (total execution time). However, HTTP callout processing time is no longer included when calculating the 5-second limit. We pause the timer for the callout and resume it when the callout completes.

Where: This change applies to Lightning Experience and Salesforce Classic in Enterprise, Performance, Unlimited, and Developer editions.

This change applies to callouts made directly from Apex, including SOAP callouts generated by WSDL2Apex. It also applies to callouts from other platform features, such as External Services and External Objects.
