Practical ways you can use Slack and Todoist
Turn completed tasks into slack updates.
When a task is marked complete in Todoist, Zapier can immediately send a Slack message to a specific channel. This keeps team members notified of progress without the need for manual updates, increasing collaboration and visibility.
Channel updates triggered by completed Todoist tasks.
When an engineer completes a task in Todoist, Zapier can post a message in a designated Slack channel. This ensures everyone knows which tasks have been completed, promoting transparency and coordination among team members.
When a new project is created in Todoist, Zapier can notify a specific Slack channel. This helps ensure everyone is informed about new projects as soon as they are initiated, improving alignment and communication.

Frequently Asked Questions about Slack + Todoist integrations
New to automation with Zapier? You're not alone. Here are some answers to common questions about how Zapier works with Slack and Todoist
How do I set up the Slack and Todoist integration?
To set up the Slack and Todoist integration, you need to authenticate both your Slack and Todoist accounts on our platform. Follow the integration setup wizard, which will guide you through selecting specific triggers from Slack and corresponding actions in Todoist. Once you've completed these steps, our system will automate task creation based on your chosen triggers.
What are some common triggers available for the Slack and Todoist integration?
Common triggers for integrating Slack with Todoist include receiving a new message in a specific Slack channel, adding a reaction to a message, or mentioning a certain keyword. These can be set to create tasks automatically within Todoist based on your preferences.
Can I create tasks in Todoist directly from a Slack message?
Yes, you can create tasks in Todoist directly from a Slack message by setting up a trigger where posting or reacting to a specific message initiates an action that creates a new task in your designated Todoist project.
Is it possible to update an existing task in Todoist when something happens in Slack?
Currently, updating existing tasks is dependent on the triggers available. Some users set updates by choosing actions like commenting or reacting in Slack that append information as comments on existing tasks in Todoist rather than altering main details.
How can I customize notifications from my integrated applications?
Notifications can be customized during the setup of your integration. You can specify which channels or types of activity should trigger notifications sent from Totoid back into your preferred communication method in Slack.
What should I do if my integration between Slack and Todoist stops working suddenly?
If your integration stops working suddenly, first check if any changes have been made to permissions or configurations on either platform. We recommend re-authenticating the apps with our service as well as reviewing any recent updates that may affect functionality.
Can I filter which messages or activities trigger actions between these platforms?
Yes, during the setup process you can define filters for what kind of messages or activities should trigger actions. For instance, only messages containing specific keywords could initiate task creation in Todoist.
