## Template Management API Version 2

Note:
As of January 31, 2026, Version 1 endpoints for managing message templates have been deprecated and are no longer accessible. Version 2 is recommended and is the only version currently accessible.

Version 2 of the Template Management API was released on September 4, 2023. We recommend using this version of the Template Management API for all template management activities via API calls. In addition to the feature set included with Version 1, Version 2 also includes:

- Strongly typed `translations` field content, allowing the user to define the message using the same JSON structure used to define messages in a [send message request](https://developers.sinch.com/docs/conversation/api-reference/conversation/messages/messages_sendmessage#messages/messages_sendmessage/t=request&path=correlation_id)
- Improved validation
- The option to override the omni-channel template configuration with a channel-specific template (for channels on which channel-specific templates can be created) using the `channel_template_overrides` field
