End an active SMS conversation with a contact.

You can only use this AMPscript function in MobileConnect.

You can’t use this function with conversation-based templates, including Double Opt-In and Info Capture templates.

The EndSmsConversation() function has two parameters:

  • originationNumber (string): Required. The phone number (such as a short code or long code) used in MobileConnect.
  • destinationNumber (string): Required. The contact’s phone number, including the country code.

Use this function while there’s an ongoing conversation with a contact. To use this function, pass it your short or long code, and the phone number of the contact.

This function always returns true if successful, and an exception if it fails. For this reason, we recommend against using this function for decision making.
