Overview

The "Validate Postcode" operation in the Validation & Cleansing resource allows users to validate global postcodes by providing a postcode string and an associated country code. This node sends a request to an external API endpoint dedicated to postcode validation, which checks the correctness and format of the given postcode within the specified country context.

This node is beneficial in scenarios where workflows require address verification or data cleansing to ensure that postal codes are valid before further processing, such as shipping label generation, customer data validation, or geographic analysis.

Practical examples:

  • Validating user-entered postcodes during form submissions to reduce errors.
  • Cleaning up bulk address datasets by verifying postcodes against country-specific formats.
  • Integrating with CRM systems to ensure contact addresses have valid postal codes.

Properties

Name Meaning
Postcode (Required) The postcode string to validate.
Country (ISO 3166-1 Alpha-2) (Required) The two-letter country code representing the country context for validation. Examples: nl (Netherlands), us (United States).

Output

The node outputs JSON data containing the validation results returned from the postcode validation API. The exact structure depends on the external API response but typically includes fields indicating whether the postcode is valid, possibly normalized or formatted postcode data, and any related metadata or error messages.

No binary data output is expected from this operation.

Dependencies

  • Requires an active connection to the Bedrijfsdata API service.
  • Requires configuration of an API authentication credential (an API key or token) for the Bedrijfsdata API.
  • The node makes HTTP GET requests to the /postcode endpoint of the Bedrijfsdata API.

Troubleshooting

  • Common issues:

    • Invalid or missing postcode or country code input will cause the API to return errors.
    • Network connectivity problems can prevent successful API calls.
    • Incorrect or expired API credentials will result in authentication failures.

  • Error messages:

    • Errors related to invalid parameters usually indicate that the postcode or country code was not provided or is malformed.
    • Authentication errors suggest checking the configured API key or token.
    • Unexpected API responses or timeouts may require retrying or contacting the API provider.
