I. Intro

By authorizing Lark Flow to use bots to send messages, users will be able to check external information without ever leaving Lark. Lark Flow is an automation tool that combines a range of products and services to enable an automatic workflow.

Bots are simplified programs that are capable of sending and receiving chat messages. When you subscribe to an event, for example, a bot may notify you the time and date, or provide you with more event details through chat.

II. Steps

Go to the Lark Developer homepage, and click Create an App.

Enter the App Name and Description. By default, the App Type is set to Custom App. Click Create in the lower-right corner.

Click the app you just created to view details.

Click Credentials & Basic Info in the left navigation bar, and find the App ID and App Secret. They will be used for authorization in Lark Flow later.

Go to Features > Bot in the left navigation bar. Click the Enable bot switch.

Click Permissions & Scopes in the left navigation bar, and go to Manage scopes. To enable your bot to receive and send messages, check the boxes next to:

Read group chat messages mentioning the bot

Go to App Release > Version Management & Release, and click Create a version.

On the Version Details page, fill in the details, and then click Save.

Click Submit for release, and the organization administrator will review your request. After approval is granted, eligible members will be able to use the app.

After the app version release is approved, you can add your bot to a group. Enter the group chat and click the Settings icon. Go to Bots > Add Bot and search for the app name myRobot in the pop-up window, then click Add.

Open Lark Workplace > Lark Flow. Click + Create in the upper-right corner to create a bot workflow.

Go to Select a Trigger > Message, select the trigger you want, and set the remaining options as needed. Click Confirm.

Go to Select an Action page, select Message in App. Select Send me a message via custom bot in Action. Select Custom Bot and click Add a bot in the drop-down list to go to the Lark Flow Authorization page.

Enter the App ID and App Secret of the app and then click Confirm to complete the authorization process.

Return to the Lark Flow Configuration page, open the Custom Bot drop-down menu, and select myRobot. In Send To, you can select Yourself or any groups that the bot has joined. Set the remaining Lark Flow options, and then click Confirm. Now, the bot will send the designated messages to selected groups.
