In general, we do not have prior API rate limits in place. We occasionally throttle requests reactively if we see problematic traffic patterns.
In general, we recommend that customers use some type of queue to manage requests, since failures can occasionally occur due to a variety of reasons. Multiple workers could be pulling from the queue, but 300 such workers is almost certainly more than they need and a burst of activity like that would be more likely to experience failures versus a sustained load over a slightly longer period of time.
