Looking for advice on mapping Zendesk contact records to Genesys Cloud Outbound campaigns. We hit a 422 Unprocessable Entity when importing via the CSV endpoint. The error cites invalid phone number formats, yet the data passes Zendesk validation.
“Phone numbers must be E.164 compliant without spaces or dashes.”
Our Zendesk export includes country codes but lacks the leading plus sign. Does the GC API require explicit formatting, or is there a Data Action to sanitize this before the campaign creation?
