92005: ContentSid Required

You sent a Messaging API request with ContentVariables but did not include ContentSid. When you send a content template, include ContentSid, and include ContentVariables only when you need to substitute template variables.

• You included ContentVariables in the request without ContentSid.
• Your application builds a template-based message request and omits the required ContentSid field before sending.
• You intended to send a Content Template Builder template, but the request still uses only variable data and does not reference the preconfigured template SID.

• Add ContentSid to the request whenever you include ContentVariables.
• Use the SID of the preconfigured content template you want to send. ContentSid identifies the template, and ContentVariables supplies the runtime substitution values.
• Format ContentVariables as a JSON string that contains the placeholder keys and values defined for your template.
• If you are sending a content template, replace Body and MediaUrl with ContentSid. Then add ContentVariables only if the template includes placeholders.

• Send templates created with the Content Template Builder
