21624: Invalid validity period value

You provided an invalid value for the ValidityPeriod parameter when creating a Message resource. Set ValidityPeriod to an integer from 1 to 36000 seconds.

• ValidityPeriod is less than 1
• ValidityPeriod is greater than 36000
• ValidityPeriod is not an integer value
• Your application passes ValidityPeriod in an unsupported format, such as a string with non-numeric characters or a decimal value

• Update your request so ValidityPeriod is an integer between 1 and 36000
• Validate the ValidityPeriod value in your application before you send the API request
• Remove ValidityPeriod from the request if you do not need to override the default message validity behavior
• Review the code that builds your Messaging API request and confirm the ValidityPeriod parameter is mapped correctly

• Programmable Messaging API reference
• Message resource
