Register a Sender Profile (issue senderKey)
After both your Business Channel and BSP registration are complete, this is the process to create a sender profile in the BSP console and receive your 40-character hex senderKey.
What is a sender profile?
A Sender Profile is the key that identifies “who is sending” when a KakaoTalk message goes out. When the BSP sends a message to Kakao, the senderKey specifies the sender (= your clinic’s Kakao channel).
The senderKey is a 40-character hex string generated in the BSP console, and you enter it in the “SenderKey” field of the Coauths CRM Connect form.
Prerequisites (all 4 required)
Before attempting to register a sender profile, you must have all of the following in place.
- Business Channel conversion complete — see the Business Channel guide
- Home visibility ON — Channel Admin Center → Home → Display settings. (Different from the plain “public” setting)
- Customer center info registered — phone number or URL
- Kakao channel admin’s phone = the phone that receives the sender profile token (these must match)
Registration steps (NHN Cloud)
- NHN Cloud console → Bizmessage → Kakao AlimTalk → Sender Profile Management
- Click + Register sender profile
- Enter the information:
- Search ID: your Kakao channel’s search ID (e.g.
@우리병원) - Phone number: must exactly match the phone number registered in the KakaoTalk Channel Admin Center
- Category: Medical/Hospital
- Search ID: your Kakao channel’s search ID (e.g.
- Request token → an SMS verification token is sent to the phone above
- Enter the token you received → registration complete
- The senderKey (40-character hex) appears next to the registered sender profile → copy it
Bizppurio steps (summary)
- Bizppurio console → Kakao → Add sender profile
- Enter search ID + phone number → verify token
- Sender profile key (senderProfileKey) is issued → copy it
Nearly identical to NHN. Only the console UI differs.
SOLAPI steps (summary)
- SOLAPI console → Channel → Register AlimTalk channel
- Search ID + phone token verification
- A Channel ID is issued → enter it in the CRM (it plays the role of NHN/Bizppurio’s senderKey)
Daily sending limit
On first registration, the BSP sets a daily limit of up to 1,000 messages (spam prevention + verifying operational stability).
Once operational stability is confirmed, you can request a limit increase from the BSP customer center:
- 1–3 months of stable operation → increase to 5,000 (typical)
- Larger increases possible after that
Frequently asked questions
Q. The token isn’t arriving by SMS
The most likely cause is that the registered phone differs from the phone number in the Kakao Channel Admin Center. Make the two match. Also check for carrier SMS-blocking settings.
Q. Can I create multiple sender profiles?
You can register multiple sender profiles on one Kakao channel, but usually one is enough. Use multiple only when operating branches separately.
Q. What if the senderKey is exposed?
On its own it cannot send messages (a BSP API key + authentication are also required). Still, for security, never expose it in plain text on GitHub, Slack, etc.
Q. What’s next?
- Write AlimTalk templates + Kakao review
- The actual integration steps in the KakaoTalk connection guide — extract the BSP API key + enter it in the CRM
📍 A phone number mismatch is the most common blocker. Verify the phone number in both places before proceeding.
