Message Template Editing is Now Available in Content Template Builder

Template editing is live for all Content API users today. You can now update existing templates (text, variables, rich content) directly via the API without needing to recreate or version manually. Editing a template does not change its Content Sid.

Why it matters

• Faster copy tweaks and fixes
• Consistent messaging template changes across channels
• Retain the same Content Sid when sending templates

How it works
Use PUT /v1/Content/{ContentSid} to update any existing template.
