Connect Drafts to Trello via URL Scheme

[André Strömgren]

Hi,

I'm trying to create an action (automation) to send the text in a Draft (app Drafts 5) to Trello to create a new card. I'm using the URL Scheme advised by Atlassian (https://support.atlassian.com/trello/docs/automate-with-url-scheme/), i.e. trello://x-callback-url/createCard?shortlink={board_shortlink}&name=MyCardName&description=MyCardDescription, which opens up Trello but does not create a new card. I've checked the parameter data from Drafts and it should be ok.

I'm stumped, please help me to understand why a card is not created?

@André Strömgren Did you figure out how to get this working?

Hi,

I just got an answer back from the Atlassian support to only use the 8 letter short code instead of the full link, but that did not work. So this is still, at least for me, an open ticket unfortunately.

@André Strömgren,

First off, welcome to the Atlassian Community and I hope you're doing well today.

Given the complexity of your question, could you please raise a ticket with us at https://trello.com/contact#/ and share the same information from your post including on which device are you attempting to use the callback URL? That would be very helpful for us to troubleshoot your case! I appreciate your understanding!

Hi and thanks!

I will do that, thanks for directing me to the right place.

I tried the same question with the Drafts community and after testing the situation out with persons more technically skilled than me we concluded that it seems to be an issue with how the URL Scheme is set up on the Trello side since I either get bounced back to Drafts from Trello without having created a card (mobile), or stay in Trello without having created a card (laptop).

You're welcome, André! Please do, and we'll be happy to review your case with you and our team to understand where the problem lies. I made a few tests on my own and got the same behavior, so I agree that something isn't right with the URL schemes. We'll be looking forward to working with you to solve this problem! Have a nice day!

In the end the Trello iOS URL scheme trello://x-callback-url/createCard worked to create cards and has done so for quite some time. This worked reliably until recently, but now Trello opens the “Create card” screen without using any of the parameters provided.

What should happen:
Opening a URL like:
trello://x-callback-url/createCard?shortlink=XXXXXXX&name=Test&description=Test
should open Trello and pre-fill the new card with the title “Test” and the description “Test”.

What happens now:
- Trello opens.
- It shows the “Create card” screen for the correct board.
- The “Name” and “Description” fields are empty.
- No card is created, even if the calling app waits for the x-callback response.
- This happens both when triggered from Drafts and when manually opening the URL from Safari, so it's not caused by Drafts.

Why I believe this is a Trello-side regression:
- The same URL (and my Drafts automation) worked correctly for a long time.
- The behavior matches Trello partially handling the URL scheme (opening the correct board) but no longer processing the name/description parameters.

Environment:
- Trello iOS app (latest version)
- iOS/iPadOS (latest)
- Tested in Drafts and directly in Safari (same result)

Could you please confirm whether the createCard URL scheme is still supported, and if so, escalate this as a regression? Many users rely on this integration for automation on iOS.

Thank you.
