Draft and send LINE OA promotions through chat
Thai marketing outlet Marketing Oops! connected Claude Desktop to a LINE Official Account through LINE's Bot MCP server and walked through checking quota, drafting a promotion, building a Flex Message and broadcasting it.
What they did
The writer enabled the Messaging API in LINE Official Account Manager, issued a channel access token in the LINE Developers Console and added the line-bot server to Claude Desktop's config file. In chat they asked Claude to check the remaining message quota, draft three promotion messages without sending, turn the chosen one into a Flex Message card with a link button, export the JSON for checking in LINE's simulator, and finally broadcast it.
What happened
The article shows screenshots of the quota check and a sent Flex Message, giving Thai marketers a step-by-step path to run LINE OA tasks from chat instead of the admin console.
Keep in mind
The coffee shop scenario is illustrative and no open or click results are reported. The writer stresses using a test account first, keeping the access token out of prompts and having a person approve any broadcast.
Try it with your agent
Using the LINE connector, first tell me how many messages are left in this month's quota. Then draft three short promotion messages in Thai for <your promotion>, aimed at <your followers>, and do not send them. When I pick one, turn it into a Flex Message card with a button linking to <landing page URL>, show me the JSON, and wait for my explicit approval before broadcasting.
Replace the <angle brackets> with your own details.
