63100: Validation Error

This error occurs when a WhatsApp Sender request body is empty, contains invalid JSON, or includes one or more fields that do not meet the Senders API validation requirements. Review the response message value or the Error Log entry in Console to identify the field that failed validation.

• The request body was empty.
• The request body was not valid JSON for a request sent as application/json.
• senderId was missing or was not provided in whatsapp:<E.164_PHONE_NUMBER> format.
• profile.name was missing for a WhatsApp sender or did not meet Meta display name requirements.
• A field used an unsupported value or format, such as verificationMethod, callbackMethod, fallbackMethod, accountType, privacyUrl, accentColor, or vertical.

• Send a non-empty JSON request body and correct any malformed JSON before retrying the request.
• Set senderId in whatsapp:<E.164_PHONE_NUMBER> format, for example whatsapp:+15017122661.
• Include profile.name and make sure it follows Meta display name requirements before you register the sender.
• Use only documented enum values. Set verificationMethod to sms or voice. Set callbackMethod and fallbackMethod to POST or PUT. Set accountType to ISV or ISVSubAccount only when you need that setting.
• Make sure privacyUrl is a publicly accessible HTTP or HTTPS URI associated with the sender.
• Provide accentColor as a valid hex color and use one of the documented values for vertical.
• Review the response message value and the Error Log entry for the exact validation failure, then correct that field and submit the request again.
