When accessing the Sauce Labs REST API, you may receive a response message telling you:
{"message": "API rate limit exceeded for some_username. See rate-limiting section in our API documentation."}
This happens when you exceed the number of allowed requests to our API for a certain time period. You can find the actual limits here.
If you're certain you're not exceeding those limits, check who the rate limit message is for. If, instead of a username, it contains 'public:' followed by an IP address:
{"message": "API rate limit exceeded for public:192.111.222.33. See rate-limiting section in our API documentation."}
This means your API request has no, or incorrect credentials. Check to make sure you're using the right username and access key.
