Board ID: 67470ced0061d56e33f4dce2
Action Type: updateCard
Action Display: unknown
We are experiencing an issue with the Trello webhook for the board listed above. During an updateCard action, the webhook is returning incorrect data — specifically in the old.idLabels field.
The old.idLabels is expected to contain only the label(s) that were removed or changed, but instead, it is returning the full list of current labels, making the "old" and "new" values identical. This prevents us from accurately detecting changes to labels on a card and is causing inconsistent behavior in our application’s tag selection logic.
Here’s a summary of the webhook payload:
New Labels (card.idLabels):
["67470cee0061d56e33f4e4f0", "67470cee0061d56e33f4e4f4"]
Old Labels (old.idLabels):
["67470cee0061d56e33f4e4f0", "67470cee0061d56e33f4e4f4"] (expected only one label here)
This appears to be a recent issue — webhook payloads were working as expected previously.
Please investigate this behavior or let us know if there are any updates or changes in how updateCard webhooks should be handled. We're also open to exploring alternative solutions if recommended.
Thank you.
