I have a series of Zaps that were working for months without issue. They would basically trigger when a message was posted in a chosen channel.
Since about mid-December, they have stopped working. Although there are definitely messages that should have triggered them, there is no Zap history for them at all.
The only thing I can find is an update to Slack polling limits, but I cannot even get these Zaps to show any test data, even when switching the trigger to something else, or when selecting optimized data.
What is going on here?




I have already tried:
- Reconnecting my Slack Connection (shouldn’t be an issue as the same connection works on non-trigger Slack actions)
- Using a different Slack trigger.
- Both Optimized, and non-optimized data.
As I have virtually the same Zap set up for multiple channels, it is also not a problem exclusive to this channel.
As mentioned, these were all working fine until mid-December, and all stopped working at roughly the same time. No error reported from Zapier’s side - it’s like it just stopped detecting the triggers at all.
