Step 2: Set Up Trigger

First, set up the trigger in Asana.
The first page reflects the account information linked with My Apps.
If necessary, modify the title and check the account information before proceeding.
Next, set the trigger interval.

The trigger interval can be set from 5 to 60 minutes, but please note that it may not be selectable depending on your Yoom plan.
In the image above, Asana tasks are checked every 5 minutes.
Select other required items from the options, perform operations on Asana, and then click "Test".

If the task information registered in Asana is added to the output, click "Save" to complete the trigger setup.
Step 3: Set Up Slack Message

Next, set up to notify Slack with task information.
On the first page, as before, modify the title and check the account information before proceeding.
Next, set the notification content using the output.

The output section reflects the acquired information.
Once everything is entered, click "Test".
The test was successful, and a notification was received on Slack.
Click "Save" to complete all settings.
Finally, turn the trigger ON.

Now, whenever a task is added in Asana, a notification will automatically be sent to Slack.
The flow you set up is as follows.
