Initiates a new bulk verification process for a list of identifiers. Each item must be an 18-char CURP (individual) or a 12-char RFC (business). Each item requires a pre-existing consent, which is automatically discovered. The entire bulk request will be rejected if the payload structure is invalid or if any individual item is malformed (e.g., missing identifier). Failures of individual verifications during asynchronous processing (e.g., consent not found for an item, identifier not found by external systems) will be reflected in the status of those individual verifications.
