# Xactus # Xactus A credit vendor integrated for consumer credit reports, with a recovered field mapping. Xactus is reached through Credit under the same canonical contract as the other bureaus. A language configuration for it survives in the committed sources, so the field-level mapping between its own vocabulary and the canonical credit classes renders below rather than being described in prose. That mapping is the whole integration surface a caller never sees. It is what makes the credit response identical in shape whichever bureau produced it, and it is why adding a bureau is a configuration rather than a change to the product. ## Products it serves - Credit - Connection ## Position in the ordering - Credit configured per lender ## Field mapping | Flow | Canonical in | Vendor in | Vendor out | Canonical out | Lender credentials | | --- | --- | --- | --- | --- | --- | | `credit-verify` | `staircase-graph` | `credit-input` | `credit-mismo231` | `staircase-graph` | — | ## How this integration is built - **connection configuration** — The wire protocol. One repository per vendor API call, not per vendor. - **language configuration** — The field mapping between the vendor's vocabulary and the canonical model. - **flow file** — The four-way translation: canonical request, vendor request, vendor response, canonical response. - **waterfall priority** — One line naming where this vendor sits in the vertical's ordering. - **status call** — Activating the vendor for a lender, optionally with the lender's own credentials. ## Evidence This vendor is on the roster because each of the following resolves to a committed artifact. - `credit-pp-data product/data/flows/xactus.json` - `mortgage-verification-credit-xactus`
