Sinch introduces KakaoTalk in its Conversation API

The new KakaoTalk channel will enable brands around the world to communicate with their customers in South Korea and beyond

STOCKHOLM, Sweden – October 12, 2022 – Sinch AB (publ), a global leader in cloud communications and mobile customer engagement, announced today that it is adding the KakaoTalk channel to its Conversations API, which enables businesses to connect Engage in seamless omnichannel interactions with consumers anywhere in the world.

With this latest addition, Sinch expands the number of channels businesses can use to connect with their customers. These include SMS, RCS, WhatsApp, Viber Business, Facebook Messenger – and now KakaoTalk, among others.

The Conversations API uses built-in transcoding, giving organizations the ability to conduct conversations across all supported communication channels and, if required, full control over channel-specific features. With the launch of this new channel in the Conversation API, brands around the world can now easily communicate with customers via KakaoTalk.

Life unfolds on KakaoTalk in South Korea. It has 53.3 million monthly active users out of a population of only 51.8 million, and there are many, not only in South Korea, using it. Businesses need to be able to interact with their customers via KakaoTalk as the app is an ideal medium for marketing, sales advice and customer support due to its high open rates and click-through rates.

“KakaoTalk is a super app that is becoming more and more pervasive in digital life in South Korea – 97% of the population uses it. However, Sinch has seen many Western brands not making good use of it. They often run basic social media and ads on KakaoTalk, but when a customer asks the brand a question, there’s little interactive dialogue within the app itself,” said Jon Campbell, director of rich messaging, Sinch. “However, with South Korea quickly becoming a hot market for global retail and travel brands, Sinch can now provide easy access to KakaoTalk for international brands via our Conversations API. So since all documents and support are in English, each company can communicate two-way with customers in the region.”

With Sinch’s large portfolio of products and services, any business can instantly interact with any communication channel it needs. The addition of KakaoTalk to Sinch’s conversations API means that instead of trying to decode Korean documentation or working with a local agency to build integration with the company’s multiple messaging APIs, companies now have a single API for all communication channels in one place and with can manage all the developer documentation needed for this, in English. With KakaoTalk now added to its conversations API, Sinch continues its goal of being able to reach anyone in the world, anytime, using their preferred messaging channel.
