Update Existing Email Templates

Use the Template REST APIs to programmatically manage the email templates that you have stored on the Braze dashboard, on the Templates & Media page. Braze provides two endpoints for creating and updating your email templates.

Use the endpoints below to update email templates on the Braze dashboard. You can access an email template’s email_template_id by navigating to it on the Templates and Media page. The email template creation API endpoint will also return an email_template_id reference.

All fields other than the email_template_id are optional, but you must specify at least one field to update.

Possible Errors

• Template Name is required

• Tags must be an array.

• All Tags must be Strings.

• Some Tags could not be found.

• "Invalid value for 'should_inline_css'. One of 'true' or 'false' was expected" - ‘should_inline_css’ accepts boolean characters only. The error likely is being shown as the value is being sent as a ‘string’.
