Brand Message is the KakaoTalk channel for marketing and promotional messages. Unlike Alimtalk, which is informational only, it can carry advertising — and unlike Friendtalk, it can reach people who are not channel friends.

v2 only. This endpoint does not exist on v1.

Prerequisites

• A Kakao sender profile key (kakaoSenderKey) → Registering a sending number
• A friendTemplateUuid from a Brand Message template registered in the console
• For promotional sends, adFlag: "Y" and compliance with the advertising rules

targeting decides the path

targeting	Audience	Mode	contacts
M	Channel friends	Single (BRAND_BASIC)	required
N	Not channel friends	Single (BRAND_BASIC)	required
I	Specified audience	Single (BRAND_BASIC)	required
F	All consenting channel friends	Broadcast (BRAND_GROUP)	not used

F names no recipients, so the response carries acceptance only, not a send count. Check results through the campaign lookup.

Message types

Send the Friendtalk code; the server converts it.

You send	Becomes	Content
FT	BT	Text
FI	BI	Image
FW	BW	Wide image
FL	BL	List
FC	BC	Commerce
FM	BM	Composite
FP	BP	Premium video
FA	BA	Carousel

The important exception: sending FT/FI/FW with M/N/I returns NOT_A_BRAND_MESSAGE here. Free-form bodies to individual recipients still go through /api/v2/friends/send. See Friendtalk shut down.

Examples by language

Node.js / TypeScript

// Single send — channel friends
await sendgo.brandMessage.send({
  targeting: 'M',
  messageType: 'FL',
  friendTemplateUuid: '9cd5460b-6458-4edc-9b11-c26d3013c340',
  adFlag: 'Y',
  contacts: [{ contact: '01012345678', var1: '29,000원' }],
});

// Single send — people who are not channel friends
await sendgo.brandMessage.send({
  targeting: 'N',
  messageType: 'FM',
  friendTemplateUuid: '9cd5460b-6458-4edc-9b11-c26d3013c340',
  adFlag: 'Y',
  contacts: [{ contact: '01012345678' }],
});

// Broadcast — every consenting channel friend, no contacts
await sendgo.brandMessage.broadcast({
  messageType: 'FW',
  friendTemplateUuid: '9cd5460b-6458-4edc-9b11-c26d3013c340',
  adFlag: 'Y',
});

// Campaign results
const list = await sendgo.brandMessage.campaigns({ count: 10 });
const one  = await sendgo.brandMessage.campaign(campaignId);

Python

client.brand_message.send(
    targeting="M",
    message_type="FL",
    friend_template_uuid="9cd5460b-6458-4edc-9b11-c26d3013c340",
    ad_flag="Y",
    contacts=[{"contact": "01012345678", "var1": "29,000원"}],
)

PHP · Laravel

<?php

$sendgo->brandMessage->send([
    'targeting'          => 'M',
    'messageType'        => 'FL',
    'friendTemplateUuid' => '9cd5460b-6458-4edc-9b11-c26d3013c340',
    'adFlag'             => 'Y',
    'contacts'           => [['contact' => '01012345678', 'var1' => '29,000원']],
]);

REST

curl -X POST https://sendgo.io/api/v2/brand-messages/send \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "kakaoSenderKey": "your_kakao_sender_key",
    "targeting": "F",
    "messageType": "FW",
    "friendTemplateUuid": "9cd5460b-6458-4edc-9b11-c26d3013c340",
    "adFlag": "Y",
    "scheduleType": "DIRECTLY"
  }'

SMS fallback

Brand Message supports replaceSms: "Y" too. Supply smsSubject, smsContent and senderKey alongside it.

await sendgo.brandMessage.send({
  targeting: 'M',
  messageType: 'FL',
  friendTemplateUuid: '...',
  replaceSms: 'Y',
  smsSubject: '[Summer sale]',
  smsContent: 'Check out our summer offers.',
  contacts: [{ contact: '01012345678' }],
});

Campaign lookup

Broadcasts only confirm acceptance, so results come from a separate call.

# List, defaults to the last 90 days
curl "https://sendgo.io/api/v2/brand-messages?count=30" -H "Authorization: Bearer $TOKEN"

# Detail — use campaignId from the send response
curl "https://sendgo.io/api/v2/brand-messages/$CAMPAIGN_ID" -H "Authorization: Bearer $TOKEN"

This returns Brand Message campaigns (BRAND_GROUP, BRAND_BASIC) only. Friendtalk campaigns live at /api/v2/friends.
