Our rate limit is 100 requests per second in live mode. In the sandbox, the default rate limit is 25 requests per second. If this is exceeded, a
429 status code will be returned to indicate that you have hit the rate limit.
Stress Testing the Sandbox
We do not recommend running load tests against our application in the sandbox. Performance and behavior are not going to accurately model what happens in the live mode environment due to mocking and "sandbox" magic which differs from that in live mode.
