Is there a way to set rate limit error auto-retry after X amount of time? or a way to manage a run or import so that it happens in chunks (without manual efforts)
Unfortunately, we don't have that option just yet, to schedule runs or attempt re-runs after a certain time. There is a ticket for this though, so hopefully that will be a thing in coming updates.
You can use webhooks if there's a way you could delay the triggers. Here's a video showing a few automations you can set up in Clay (webhook example in the first few minutes of this video): https://youtu.be/yw5paDolwTQ?feature=sharedWhile that video doesn't show this exactly, maybe that could help.
