92006: The Content Sid is Invalid

This error occurs when you send a Message request with a ContentSid value that is not recognized as a valid Content Template SID. Use a valid 34-character SID with an HX prefix, and retrieve it from the Content Template Builder in Console or from the response when you create or fetch a template with the Content API.

• The ContentSid value does not match the required SID format and does not start with HX.
• The ContentSid contains a typo or refers to a template SID that does not exist.
• The template was deleted from your account.
• The template belongs to a different Twilio account than the account sending the message.
• You used an identifier from a WhatsApp template workflow that is not a Content Template SID. Only Content Templates can be sent with ContentSid and ContentVariables.

• Copy the ContentSid directly from the Content Template Builder in Console or from the Content API response instead of entering it manually.
• Verify that the SID is 34 characters long and matches the ^HX[0-9a-fA-F]{32}$ pattern.
• Fetch or list your content templates to confirm that the template exists, has not been deleted, and belongs to the same account that is sending the message.
• Replace the invalid or deleted template SID with an active Content Template SID and send the request again.
• If you are sending WhatsApp templates, use a Content Template SID with ContentSid instead of a template identifier from the WhatsApp Templates console flow.
