"Wow! I missed another task due today..."
"I wish there was an automation that would notify me of overdue tasks..."
Even though you register tasks in Todoist, checking them daily can be surprisingly challenging.
How about an automation that notifies you of task deadlines and overdue tasks?

For example, there is an automation that retrieves tasks due today from Todoist and notifies you on Slack daily, or an automation that notifies you of overdue tasks on Slack every day.
<span class="mark-yellow">By implementing these automations, it will become easier to check high-priority tasks.</span>
Furthermore, if you set it up to be shared within the team, it should become easier to share task details.

In this article, we will introduce how to set up automation to notify Slack of Todoist tasks with images!

For those who want to try it quickly

By using Yoom, you can easily integrate Todoist and Slack without any code.

Yoom provides templates for integrating Todoist and Slack in advance, so you can achieve integration immediately just by registering, even without API knowledge.

Retrieve Overdue Tasks from Todoist Daily and Notify on Slack

This is a flow that retrieves all overdue tasks and notifies them on Slack!
It allows for smooth handling of overdue tasks, making it easier to prevent project delays.

Let's Create a Todoist and Slack Integration Flow

Let's get started by creating a flow that integrates Todoist with Slack!
This time, we'll use Yoom to proceed with the integration of Todoist and Slack without any coding. If you don't have a Yoom account yet, please create one using this registration form.

[What is Yoom]

This time, we will create a flow bot that "retrieves tasks due today from Todoist and notifies them on Slack".
The creation process is broadly divided into the following steps.

  • Integrate Todoist and Slack with My Apps
  • Copy the template
  • Set up the schedule trigger and configure Slack actions
  • Set the trigger to ON and complete the flow operation preparation

Step 1: Register Todoist and Slack as My Apps

Please register Todoist and Slack as My Apps to connect them with Yoom.
By registering My Apps in advance, you can proceed with automation settings smoothly.

Register Todoist as My App

1. First, let's register Todoist as My App.
Click "My Apps" → "Add" on the left side of the Yoom screen.

Search for Todoist from the app list or use the search function to find it.

2. Enter your "Email Address" and "Password" on the screen below to log in.

Register Slack as My App

3. Next, register Slack as My App.
Just like in (1), click Slack from the "New Connection List" in Yoom and sign in.

Enter your workspace URL and click "Continue".

4. You will be redirected to the Slack access permission request screen from Yoom.
Click "Allow" to complete the integration.

Once each is registered as My App in Yoom, the integration is complete!

Step 2: Copy the Template

1. To set up automation, click "Try it" on the banner below.

2. Read the screen display below and click "OK".

Step 3: Set Schedule Trigger Action

1. Let's start setting up the flow! First, click the red frame below.

2. You can set any schedule on the screen below!
(You cannot specify the time in minutes.)

Set the schedule and click "Save".

Step 4: Set to Retrieve Tasks from Todoist

1. Next, click "Retrieve List of Tasks Due Today".

2. The screen below will be displayed, check the settings and press "Next".

  • "Title" → Can be freely changed
  • "App" → Todoist
  • "Account Information to Link with Todoist" → Check for any discrepancies in the account
  • "Action" → Retrieve List of Tasks Due Today

3. When the screen switches, click "Test". If the test is successful, the output can be retrieved.

Since this value will be used in the next setting, check and save the retrieved content.

This allows you to retrieve tasks due today!

2. The screen below will be displayed, check the settings and press "Next".

  • "Title" → Can be freely changed

3. Enter the "Channel ID to Post" from the candidates.

4. Set the content of the message to be sent.

By utilizing the output, the content can vary with each flow activation.
Standard text can be set by entering it directly.

This time, it was created as follows, but try setting the content according to your work!

5. After completing the settings, click "Test".
If the test is successful, confirm that the notification is sent to Slack!

After confirmation, click "Save".

Step 6: Set Trigger to ON and Check Operation

Finally, click "Turn Trigger ON" to complete the automation settings!
Make sure the flow bot starts correctly.
