SubItems and Webhooks

I know it’s mentioned several times in here that subitems are in beta and not fully supported. Was hoping we could trigger a webhook on change of a subitem status, but it doesn’t appear to be happening. Can this be done? Should be looking at column changes instead? What is the timeline for something like this with subitems?

Hi there @holodnicka! Congrats on making your very first post with us, and I hope there are plenty more to come :slight_smile:

To be transparent with you, I don’t think this is part of the webhook feature set just yet, and I’m afraid I can not provide an ETA on when it would be either. That said, I would definitely recommend considering using our API v2 to work with sub-items instead - it already supports most of the things you are able to do with items, and considering what you are looking to do, I think it would be a great fit.

What do you think?


Hi @AlexSavchuk

I am too trying to work with subitems.

You are correct, the API v2 lets me query and mutate subitems, but what I am looking for, is a way to emit a trigger when a subitem is being edited. Is there a way to do this?




Thank you for bumping this one! I do think we might have a way to get this to work by using custom triggers and webhooks. Could you please take a look at the amazing solution that @basdebruin has provided in the community?

What I’m thinking is that you could use the sub-item board ID to attach the webhook there, and assign webhooks to specific column values being changed. That said, transparently, I have not tested this out myself.

Hi Alex

Thanks for the reply.

I read @basdebruin’s post and managed to create a webook for a regular board using the API mutation, this works great.

However when trying to apply the webhook to a board of subitems, I get a response beginning with {“data”:{“create_webhook”:null…

Furthermore, the challenge token is not being sent to the webhook url provided. It seems that a board of subitems cannot have a webhook attached to it.

If anyone manages to attach a webhook to a board of subitems, please let me know.


Confirmed not working through mutation API.

The exact same request (epsilone boardId and columnId) works on a “main Board” but not on a “Subitem Board”

And yes, this is very big blocker for our automations, which I write a few per day (Integromat). Missing this feature so much
