Keyless Costa Rica Hacienda v4.4 comprobante validator: official XSD for 8 document types, the 50-digit clave numerica, CABYS code lists, totals/IVA math, XAdES-EPES signature check. Rule-coded JSON r
The GET Health check endpoint returns a simple JSON object indicating the service status, while the POST Validate e-invoice endpoint returns a detailed JSON validation report that includes fields such as validity, document type, version, signature validity, error count, and findings related to compliance with Hacienda v4.4 standards.
Key fields in the POST Validate e-invoice response include "valid," "wellFormed," "documentType," "version," "signatureValid," "errorCount," "warningCount," and "findings," which provide insights into the validation status and specific compliance issues.
The response data is structured in a JSON format. The main validation status is presented at the top level, followed by detailed findings categorized by level (info, warning, error) that describe specific compliance checks and their results.
The GET Health check provides service status, while the POST Validate e-invoice offers comprehensive validation details for electronic invoices, including document type, version, signature checks, and compliance findings based on the official XSDs.
The POST Validate e-invoice endpoint accepts the raw XML of the Comprobante Electronico as the request body. No additional parameters are required, as the document type is auto-detected from the XML content.
Data accuracy is maintained through adherence to official XSD schemas and validation rules established by the Costa Rican Hacienda. The API checks for compliance with these standards, ensuring that the validation results reflect the current regulatory requirements.
Typical use cases include validating electronic invoices for compliance with Costa Rican tax regulations, ensuring proper document formatting, and verifying the integrity of digital signatures in e-invoices before submission to the Hacienda.
Users can utilize the returned data by interpreting the validation report to identify compliance issues, addressing any errors or warnings, and ensuring that their electronic invoices meet the necessary standards for acceptance by the Costa Rican Hacienda.
