How can I connect Slack and Trello porperly

[Yu Saotome]

I am currently having trouble connecting Slack with Trello.
It will be very helpful if you can teach me how to solve the issue.

• I only can choose one workspace board (I'm using two and both are already linked with slack)
• I can send message from Trello to Slack
• I want to disconnect Slack with one of the workspace (I don't want to delete the entire workspace)

Hi! For the first question, are you trying to connect to Slack from within Trello, or to Trello from within Slack? Or both? Can you tell me more about how you're trying to use them together?

For your second question, there isn't a way to send a regular Slack message from Trello, but you can send a Trello card to someone in Slack using the Slack Power-Up in Trello. After you've installed the Power-Up, there will be a Slack button on the card back with some options:

For your third question, there are a couple of ways to do this:

1. In Trello, go to the settings page for your Trello Workspace. Then, under Slack workspaces linking, you should see the Slack workspace that's linked. From there, you can click the Change button and then Unlink.
2. You can also use enter "/trello unlink-team" in Slack to un-link the Trello Workspace.

@Yu Saotome technically you can build automation to send a message to Slack, but you'll need to define that automation:
