This issue has now been resolved, however some clients may need to make modifications to their integration in order to continue to connect to our API, as our SSL certificate has been updated (for the majority of clients affected by this incident however no change should be required). We are continuing to monitor the situation and will update this notice if anything changes.

Please contact us at if you experience any further issues connecting to our API, or if you need any additional support.

We are currently investigating an issue affecting a number of clients, which appears to be the result of the expiry of the AddTrust External CA Root (root certificate) on 30 May 2020.

While our SSL certificate is valid until 5 January 2021, and our API instances and website are fully operational at present, clients that are affected by this issue may receive "Certificate expired" errors on attempting to connect to our API.

We are currently working to identify which clients may be affected by this issue, and the steps that are required to remedy it. We will update this notice as soon as we have any further information.

Please contact if you experience any issues connecting to our service.
