I’m getting an HTTP Error 429 Too Many Requests when doing a bulk upload/download

A 429 error means you are encountering the Xero Rate Limits for their API. The most common one we see is the Minute Limit of 60 calls per minute. The easiest way to resolve this is to add a pause to the looping script using the Pause/Resume Script script step to the loop so that is pauses between iterations (e.g. 1 second) which will slow the script down so that it doesn’t hit the Xero Rate Limits.
