When the Kakao Chatbot Isn't Responding

If a customer messages your Kakao Talk channel but the Biseo AI assistant doesn't reply, check the following.

This covers the conversational chatbot connected to your own salon's Kakao Talk channel. It's a different feature from the separate support-site AI chatbot, which hasn't launched yet.

Example: Say a hair salon on the Growth plan recently reconnected its Kakao Talk channel, and ever since, the chatbot hasn't answered any customer booking enquiries. The plan isn't the issue — it's Growth. Digging further, it turns out that reconnecting the channel automatically rotated the secret in the webhook URL registered in the Kakao Business console. The old webhook URL still saved on the Biseo side no longer matched the new one in the Kakao console, so messages were never delivered. Fixing it is simple: copy the current webhook URL from the Biseo admin screen again and paste it into the skill settings in Kakao i Open Builder.

1. Check your plan: The chatbot only works on Growth plan or above. On lower plans (Free/Starter), the chatbot feature itself is disabled, so confirm your salon's current plan first.
2. Check the Kakao i Open Builder webhook URL: Confirm that the skill (webhook) URL registered in your salon's own Kakao Business console still matches Biseo's current webhook URL. This URL contains a secret unique to your salon, so the connection can break if the URL was copied incorrectly when it was set up, or if the value changed after reconnecting your Kakao channel. Recheck the current webhook URL in the Biseo admin screen and compare it character-for-character against the value saved in the Kakao console.
3. Check the Open Builder fallback block connection: In the Kakao i Open Builder console, confirm the fallback block is still correctly connected to the Biseo skill (the webhook URL above). It's common for this connection to break after changes are made to the Open Builder configuration on the salon's side — for example, adding a new scenario or block can accidentally detach the fallback block's skill link, leaving the chatbot silent even though the webhook URL itself is fine.
