WC Gateway Monitor watches every active payment gateway silently — on a schedule. The moment one fails, you know. Not your customers.
| Gateway | Endpoint | What we verify |
|---|---|---|
| Stripe | GET /v1/charges?limit=1 | 200 = valid key · 401 = wrong key · 429 = rate limited (alive) |
| PayPal | POST /v1/oauth2/token | 200 + access_token = valid · 401 = wrong credentials |
| Authorize.Net | POST authenticateTestRequest | resultCode = "Ok" = valid · Error = wrong credentials |
| Square | GET /v2/locations | 200 = valid token · 401 = wrong or expired access token |
| Any other gateway | HTTP HEAD on endpoint URL | 2xx/3xx/4xx = reachable · Timeout/5xx = network failure |
