PROGRAMMABLE SMS
ERROR
Failed to send freeform message because you are outside the allowed window. If you are using WhatsApp, please use a Message Template.
- After April 1, 2025 WhatsApp templates can only be sent using Content Sid and Content Variables. Templates sent using body outside of a conversation window will fail with this error.
- This message failed to be delivered to the user because it was sent outside the messaging channel's allowed conversation window. For WhatsApp messages initiated by the business, you must use a pre-defined template.
- If the message was created with Content API or Content Editor it may be one of the following issues:
- The customer is still using "body" instead of "Content SID" and "Content Variables"
- The customer is using content type that is not supported for business initiated conversations, e.g. listpicker or location
- For Facebook Messenger messages initiated by the business, only publishers registered with the Facebook News Page Index (NPI) are allowed to send notification messages outside the 24-hour window.
- Send a WhatsApp message using a template
- Include all the necessary parameters for a Content API or Content Editor Template and make sure you aren't sending with the wrong parameters
- If you are a publisher, register your Facebook Page with the Facebook News Page Index
