Fine-tune the design for each channel—like WhatsApp, KakaoTalk, and WeChat—while Conversation API handles the delivery behind the scenes.

WHY IT MATTERS

Precision messaging on WhatsApp, KakaoTalk, and WeChat 

Channel Message Templates give you channel-specific messaging templates for WhatsApp, KakaoTalk, and WeChat, helping you reach users worldwide. Ship compliant, rich messages in seconds by referencing a template_id instead of hand-coding payloads. 

Save valuable dev hours 

Reuse complex channel JSON with a single template ID and stop rewriting payloads for every message call.

Stay policy compliant 

Keep your messages aligned with WhatsApp, KakaoTalk, and WeChat rules by relying on approved templates. 

Granular control over every detail

Customize layouts, media, and variables per channel while Conversation API takes care of the delivery. 

SPEED & EFFICIENCY 

Ship messages faster with easy reuse 

Stop hand-coding identical payloads. Store the template once, reference its ID, and let Conversation API handle the rest, so you can focus on features, not formatting. 

  • Cut repetitive JSON work 

  • Reduce risk of formatting mistakes 

  • Move faster during releases

Frequently asked questions 

You’ll need a Sinch account, access to Conversation API, and the ability to register templates with each channel provider. Templates must be approved by WhatsApp, KakaoTalk, or WeChat to ensure compliance. Sinch upholds strict security and compliance standards throughout the process.

When should I use Channel Message Templates instead of Omnichannel Templates? Use Channel Message Templates when a message is highly specific to WhatsApp, KakaoTalk, or WeChat. Omnichannel Templates are best for adapting content across multiple channels. 

No. Registration and approval are channel-specific:

• WhatsApp: Create with the Sinch Build Dashboard or Provisioning API and have templates uploaded and approved by Meta.

• KakaoTalk: Templates are registered by Sinch on your behalf, but approval is required by KakaoTalk.

• WeChat: Templates are pre-defined by WeChat, then select them in your WeChat Admin portal.

Yes. Add placeholders in your template and fill them with variables in your SendMessage request. 

Build and store the exact JSON channel with a unique template_id through the Message Composer in the Sinch Build Dashboard or the Provisioning API.

Currently, we support WhatsApp, KakaoTalk, and WeChat—platforms that require pre-registered templates.

No. This is included with Conversation API. You only pay the normal per-message fee for the chosen channel.

If you don’t have one, Conversation API can fall back to an Omnichannel Template as needed.

Store the approved template, reference its template_id in your request, set the channel to WhatsApp, and include any variables.
