Is it possible to get custom fields updates through webhook ? And set values through API ?

[diadys]

Using Trello Custom Fields power-up, I'd like to get custom fields updates through webhook and set them through the API while creating cards.

But when I add or update custom fields to a card, no webhook are triggered.

I currently create a scheduler which get custom fields and compare new values to old ones, which is not very efficient.

Anyone has an exprience with this ? Got some infos from trello ?

Many thanks.

Hey Didier,

API access to Power-Ups data, such as the custom fields is currently read only, so only GET requests can be used to access this data. We're looking into adding write access for these as well, although we don't have an ETA yet for when that will be available.

You can view it with a GET request to /1/boards/[boardId]/pluginData and /1/cards/[cardId]/pluginData.

Hi,

Thanks for your reply. I'll follow the update adding the write access and webhook notifications.

I'm currently using the API to retrieve the pluginData as you described. I have  a cron that periodically checks if the data has changed which is a work-around but not very efficient.

Best regards.

Hi,

pluginData are not accessible anymore through the GET requests you've listed above.

It returns an empty array.

I've noticed it is now available to define more than 5 custom fields. Is there a change on this new version I've missed ?

Thanks.

Hi,

I'm working on open-source Trello <-> Magento 1 integration module, also connecting it with working store. Store used Zapier for a long time, and it seems to be able to edit plugin fields (Like Shippo and custom fields power-ups). We've made a lot of work already: statuses, comments and order data already processing with Trello API, but it seems that I cannot work with power-ups to do simple things like fill the custom field or attach Shippo track to card.

Is there's really no way to do this, and how Zapier do? It works with some kind of closed API?

Thanks.

Trello added support for writing custom fields and webhooks recently: https://developers.trello.com/v1.0/docs/getting-started-custom-fields

This is so great! Thanks a lot! And sorry for disinformation: Zapier is not working with parcel power-up, we just misuderstood each other with our PM. 

Thank you very much for your reply, it's really what I looked for.

Many thanks.

We've updated that and removed our useless polling bot.

Cheers.
