validate

A helper method used internally by the SDK to perform minimal validation on the object before sending it to the server.

This method checks the following in order:

• firstName is not empty

• lastName is not empty

• phone is not empty

• phone is valid per PhoneValidator.isValid. The phone number string is stripped of any special characters before validation, using PhoneValidator.removeSpecialCharacters.

• email is not empty

• email is valid per EmailValidator.isValid.

• address.postalCode is valid per ZipCodeValidator.isValid.

Return

A MissingInformationError with an error string identifying one of the above issues, or null if the object passes validation.
