Due to required infrastructure changes, the non-interactive (bot) login endpoint has been updated to https://identitysso-cert.betfair.com/api/certlogin
The new endpoint is now live and also available for the following jurisdictions:
The previous endpoint (https://identitysso.betfair.com/api/certlogin) will be retired and no longer available after Thursday 20th December 2018. Any attempts to use the old endpoint after this date with return the CERT_AUTH_REQUIRED error.
We recommend that you update your code as soon as possible with the new endpoint. Existing certificates will continue to work with the new endpoint and don't need to be updated.
