Webhook to self-signed certificate

I’m trying to use the Webhook integration to send uplink data to my device for further processing. Although the base url is configured to use an https://x.x.x.x:8443 connection it is unsuccessful due to my device having a self-signed certificate, reported error is “x509_certificate_invalid”.

Is there a way I can configure the integration to ignore this error, or connect using http rather than https?

No to either.

But you could use LetsEncrypt to provide a real certificate.
