# Verify a gateway account's credentials

> Runs the gateway's read-only health probe.

<api-operation method="POST" path="/v1/businesses/{biz}/gateway_accounts/{gwa}/verify">
<template v-slot:docs="">

Some gateways add named checks: Adyen reads the API credential's Allowed origins and fails when the storefront origin (from `PORTAL_BASE_URL`) is missing, because the card form loads only on an allowed origin.
