ACME API reference - Plugin

Monitoring and debugging

The ACME plugin exposes several endpoints through the Admin API that can be used for debugging and monitoring certificate creation and renewal.

To configure and enable the plugin itself, use the /plugins API endpoint. The /acme endpoints only appear once the plugin has been enabled.

Apply certificate

Endpoint

/acme

Applies or renews the certificate and returns the result.

Request body

`host` required	The domain where to create the certificate.
`test_http_challenge_flow` optional	When set, only checks if the configuration is valid. Does not apply the certificate.

Update certificate

Apply or renew the certificate and return the result. Unlike POST, PATCH runs the process in the background.
