Rate Limit
also throttling
A cap an API sets on how many requests you can make in a given time window, beyond which requests are rejected or delayed.
Analogy
Like a highway on-ramp meter releasing only so many cars per minute.
Why it matters
Hitting rate limits causes failed steps, so you must throttle, batch, or add delays to keep automations reliable.
In practice
An API returning HTTP 429 after 100 requests per minute forces you to add a delay step.
