In StoreCRM, Shopify Flow can be used to trigger a line to be sent when a Shopify app VIP's rank rises or falls.
Examples of measures that can be implemented
- Send out a LINE notifying you of special offers and other information when you increase your rank.
Send a line from StoreCRM at the timing of the rank increase.

Create a Flow in Shopify Flow starting with the trigger "Customer rank increased" when the VIP's points change.

Next, select the StoreCRM action. 3 actions are available for sending StoreCRM LINE: LINE Send StoreCRM Message (send a message defined in StoreCRM via LINE), LINE: Send Flex Message ( LINE: Send Flex Message ( Send Flex Message in LINE)" and "LINE: Send Text message ( Send Text message in LINE)".
This time, we will use "LINE: Send Flex Message (Send Flex Message on LINE)" to make use of the variable given by the VIP's "Customer's points changed" trigger in the LINE message.

Of the three setting items in the "LINE: Send Flex Message" action, the alternative text and the Flex Message content are required fields.
The content of Flex Message must be entered in json format. json format code generated by Flex Message Simulator, for example, can contain variables given by the "Customer points changed" trigger, so that instead of text, the current The json format code generated by Flex Message Simulator or similar can be used to display the current number of points, etc., instead of the text.

If the line is sent as shown in the image above, it is working fine.
