Not sure if that helps, but DomainOffensive offers a LetsEncrypt API:

first method: acme.sh:
export DO_LETOKEN="02pAPacMv1yNnUzSDR75"
acme.sh --issue --dns dns_doapi -d meineDomain.de -d *.meineDomain.de

second method: GET-Request:

example

https://my.do.de/api/letsencrypt?token=1md6xRcUCTrB58kbpwAH&domain=_acme-challenge.testdomain.de&value=OVxwaDm7MgN1IRG0eSivJMlepO9CL4X8vKo6Tcns

parameters:

token= - auth token
domain= - full domain name, including _acme-challenge as well as subdomains
