[What is Yoom]
This time, we will create a flow that integrates data into Slack when a specific email is received in Outlook!
The creation process is broadly divided into the following steps.
First, let's connect Outlook and Slack to My Apps.
Once logged into Yoom, click "Add" from "My Apps" in the left menu.

[For Outlook]
1. Search for "Outlook" and select Outlook from the list of apps.

2. Enter the email address of the Microsoft account you want to connect.

3. Enter the password.

This completes the connection of Outlook to My Apps.
For the registration procedure and precautions for My Apps in Microsoft365 services, please also refer to this page.

2. After signing in to the Slack account you want to connect, set the following:
After completing the settings, click "Allow".

This completes the connection of Slack to My Apps.
Once the My Apps connection is complete, let's quickly set up the template.
Click "Try it" on the banner below to copy the template.
When a template is copied to Yoom, the following screen will be displayed, so press "OK".

(1) Click on "When a specific subject mail is received" at the top of the template.

(2) Enter the account information for the Outlook you want to integrate with and click "Next".
If you have already completed the app integration, the information of the integrated account will be automatically entered.

The list of email folder IDs in the integrated Outlook will be displayed in "Options", so select from there.

(4) Specify the subject of the email that will trigger the flow bot in "Keyword".
For example, if you set it to "Meeting", only emails with "Meeting" in the subject will trigger the flow bot after being received.

Once the settings are complete, send an email that matches the conditions and click "Test". If the test is successful, click "Save" to complete the setup.
(1) Click on "Send message to channel" in the template.

(2) Select the account you want to integrate with and click "Next".

(3) Set the Slack channel to be notified in "Channel ID to Post".
You can select a channel from the integrated account in "Options".

(4) You can set "Message" as desired.
You can set the text optionally, but it is also possible to quote the content of the received email in the message from "When a specific subject mail is received" in "Retrieved value".

Once the settings are complete, click "Test" to check if the message is delivered as configured.
If the test is successful, the setup is complete.
With this, all settings are complete.
After completing the setup, a pop-up like the one below will be displayed, so turn ON the trigger.
