API

Enhancements

Error responses now include clientRequestId and correlationIdNon-200 error responses from the /v3 API now include two optional tracing fields. The clientRequestId field echoes back the value supplied in the request. The correlationId field identifies the request flow when a correlation ID is available. Use them to correlate error responses with the originating request and the request flow. Prove omits clientRequestId when the request didn’t include one and omits correlationId when none is available for the flow. Success responses are unchanged.
Pre-Fill

Enhancements

More accurate PO Box filtering for Pre-FillPO Box detection is now more exact for US Pre-Fill verifications. PO Box addresses are still excluded by default from the addresses returned in /v3/verify Pre-Fill responses. Contact your Prove representative if you need PO Box addresses included in your configuration.
