Hi, I tried to integrate mailchimp to my Mautic but i got a “SSL certificate problem”. If I understand well this problem it’s because mailchimp try to find a certificate on my redirect URL and as it’s not https he can’t find it. Can I solve this problem without have a https for my mautic URL? Is there any solution? Thx Loic ---

Current version of the Mailchimp integration uses oAuth2 for authentication which requires a SSL certificate. There is a pull request since yesterday which uses the Mailchim API key instead: [https://github.com/mautic/mautic/pull/1184](https://github.com/mautic/mautic/pull/1184) Not sure if it allows communication without SSL yet because I’m experiencing another problem described in the pull request comment. The API key authentication for Mailchimp integration should be part of Mautic 1.2.3 ---

Hi Escopecz, Thanks to reply. I update my Mautic to 1.2.3 but I still have the same “SSL certificate problem”. I follow this video to do it: [https://zippe.biz/mautic-marketing-automation/mautic-marketing-automation-integrating-mailchimp-into-your-mautic-system/](https://zippe.biz/mautic-marketing-automation/mautic-marketing-automation-integrating-mailchimp-into-your-mautic-system/) What I do wrong? What should I do to solve it? Thx Loic ---

The OAuth method of authorization is still there in Mautic for backward compatibility. You have to delete the old Mailchimp credentials and then the new authorization by API key will show up. Take a look at [https://www.mautic.org/docs/plugins/mailchimp.html](https://www.mautic.org/docs/plugins/mailchimp.html) But I’m not sure if it solves the certificate problem. The certificate configuration isn’t a Mautic issue. You can contact your server provider and ask them to take a look at it. ---

Ok, I’ll check my server and try to implement SSL. thanks ---
