Each endpoint returns validation results specific to the data type. The Email Validation endpoint returns whether the email is valid and its normalized form. The Phone Validation endpoint provides the validity status, normalized E.164 format, and detected region. The IBAN Validation endpoint indicates if the IBAN is valid, along with its country code and length checks.
Key fields include "valid" (boolean indicating validity), "normalized" (formatted version of the input), "region" (for phone numbers), "country" (for IBANs), "length" (for IBANs), and "message" (providing additional context about the validation result).
Each endpoint accepts a single parameter: the data to be validated. For Email Validation, provide an email address; for Phone Validation, provide a phone number; and for IBAN Validation, provide the IBAN. Ensure the input is in the correct format for accurate validation.
The response data is structured as a JSON object. It includes key-value pairs where each key corresponds to a specific aspect of the validation result, such as "valid," "normalized," "region," "country," and "message," making it easy to parse and utilize programmatically.
The Validex API utilizes a combination of reliable databases and validation algorithms to ensure data accuracy. The API continuously updates its validation methods to maintain high-quality standards and adapt to changes in data formats and regulations.
Typical use cases include validating user input during registration forms, ensuring accurate contact information in CRMs, and verifying financial data in fintech applications. This helps reduce errors, prevent fraud, and enhance user experience.
Users can leverage the returned data to enhance application functionality. For instance, normalized email addresses can be stored for consistency, while validated phone numbers can improve communication efforts. The validity status can also trigger alerts for invalid entries.
If a validation request returns an invalid result, users should implement error handling to prompt users for corrections. For empty results, ensure that input data is not null or improperly formatted before making requests to avoid unnecessary API calls.
