68004: Input Error

You may see this error when Verify rejects malformed or incomplete input while starting a verification or submitting a verification check. Review the parameters you send and confirm they match the required formats, required fields, and SID patterns for the Verify endpoint you are calling.

• The to value is missing, or the destination phone number is not in E.164 format when you start or check a phone verification.
• The channel value is missing or not one of the supported Verify channels for starting a verification, such as sms, call, whatsapp, email, sna, or auto.
• The request uses an invalid serviceSid value that does not match the required VA SID format.
• A verification check request does not include either to or verificationSid, or the verificationSid value does not match the required VE SID format.
• A code-based request sends a code or customCode value outside Verify's supported 4 to 10 character range.
• An SNA verification check omits snaClientToken or sends a value that does not match the token returned by the SNA URL invocation.

• Send the request in application/x-www-form-urlencoded format and include all required parameters for the endpoint you are using. A new verification requires to and channel. A verification check requires either to or verificationSid.
• Format destination phone numbers in E.164, for example +14155552671, before sending the request.
• Validate serviceSid and verificationSid before you submit the request. Verify Service SIDs start with VA. Verification SIDs start with VE.
• If you start a verification, use only a supported channel value for Verify.
• If you use customCode or submit a code in a verification check, keep the value between 4 and 10 characters.
• If you use Silent Network Auth, pass the snaClientToken from the SNA URL invocation into the verification check request.
