The app returned "Rate limit exceeded: requests per interval for API token".
Asked by hank nahum:

I am getting the following error on Zapier when a zap is supposed to occur from Zapier to Trello - how do I fix this?

The app returned "Rate limit exceeded: requests per interval for API token".

body: Hi,

As I don't know the specific setup, you have it's dificult to tell you how. You have to reduce the number of requests over time.

> There is a limit of 300 requests per 10 seconds for each API key and no more than 100 requests per 10 second interval for each token. If a request exceeds the limit, Trello will return a 429 error.

[https://help.trello.com/article/838-api-rate-limits#:\~:text=There%20is%20a%20limit%20of,will%20return%20a%20429%20error.](https://help.trello.com/article/838-api-rate-limits#:~:text=There%20is%20a%20limit%20of,will%20return%20a%20429%20error.)

A very simple way to do so is to add a delay after each request.

Hope this helps or maybe you can exlplain your setup a bit.

body: Hey Reto,

I have a paperform \> zapier \> trello zap set up

I'm auto pulling field from the form, creating a new card \& mapping the appropriate custom fields \& labels

For some reason I kept getting the error when testing my zap \& sometimes certain fields are available from the paperform but they aren't being added to the custom fields of the new cards after its been set up.


author: Reto Gehring _Valiantys_
body: Well in this case I suggest to use the zapier helper "delay after queue", to avoid the rate limit problem.

Just add this helper between the paperform and the trello connector.

author: hank nahum
body: Thanks Reto - where is this Queue Title being added? Is it needed?

Also - on any given day the submissions vary from 10-30 different submissions. How would you suggest we get this added to ensure it doesn't fail on entry or skip updating specific fields via Trello?

If there's a delay component in Zapier, then I'd recommend setting one custom field value, waiting 2 seconds, then setting another custom field value and so on, ie. set each field one at a time then pause.

How would that work if I'm passing all that data to one unique NEW card being created within Trello from the same zap?

Would it looks something like this? How do I ensure it's passing the data to same card ?

author: hank nahum
body: Hmm I'm not sure if Zapier offers such an option but I'll play around with it to see if that's possible.

Do you know if this would happen on the same zap or it'd need an entirely new zap for the next fields?


author: Iain Dooley
body: [@hank nahum](/t5/user/viewprofilepage/user-id/3953556) I don't have a Zapier account anymore but I'm pretty sure if you create a Trello card then the id of the created card is available to use with a subsequent search so you can operate on the card (or use the card in actions with other apps). You can definitely do it in the same Zap, you'll obviously have to be on the paid plan because it's a multi-step Zap.


author: Reto Gehring _Valiantys_
body: [@hank nahum](/t5/user/viewprofilepage/user-id/3953556) Yes it would look like you mentioned above, however I saw that the minimal delay is 1 minute, that might be not acceptable for your solution.

I don't have particular expirience for your case so I'm not able to give you the correct parameters. You might have to play around with the parmeters to find a setup that is feasable for your case.
