Filter by Zapier throttle?

  • 1 March 2023

Our organization is starting to use Zapier quite intensively lately with a lot of filters that run when a contact in Nationbuilder has a certain tag, but not another.

The way we do this:

Trigger: Person updated in Nationbuilder

Action: Filter by Zapier: Only continue if person has tag A, but not tag B

And then some more actions.


We have 200+ filters set up this way.

Now I’ve noticed the Filter by Zapier step shows a “Held/Throttled” for a lot of Zaps. There’s no error message and I can’t find if there’s a limit on the Filter by Zapier action, but I suppose there is.

We’re on a paid plan.

How can we resolve this?

Thanks in advance,

Hey there @OSP, great to hear you making good use of Zapier! 🙂

If the Filter is only checking to see if tag A rather than tag B has been applied then I don’t think you’d be hitting any limits on that front. I suspect that they may have been “Held/Throttled” due to the Zap triggering too many times within a short period of time. Do you think that could be the case?

As you mentioned you’re on a paid plan it should be possible to replay the "Held/Throttled" runs of Zap to see whether they are now able to go through. You can find out more about how to fix “Throttled by Zapier” errors here: Fix "Throttled by Zapier" or "Zapier has blocked this task" errors in Zaps 

If it’s not down to the Zap triggering too frequently, can you click onto one of the “Held/Throttled” runs of the Zap in the Zap History? I’m hoping that in the details for the Zap run it will show the reason as to why was held. Please can you give that a try and let us know what you find?

Hey Sam, thanks for your reply.

I don’t think it’s because a Zap triggered too frequently, as it also happened on a newly activated Zap and on one that doesn’t run all that often. They all show a Held/Throttled, without any error messages.

I also noticed it also occurs on other actions than ‘Filter by Zapier’. 

Here’s what it looks like:


I turned off a bunch of Zaps and replayed a couple of Zaps that were throttled, and these now run fine.
