Was looking on roadmap for TransIP as DNS Provider, but only found older card for API to create servers. Using Hetzner for servers, but for DNS I use TransIP. Guess I will have to do wildcard DNS manually like with Forge. Would be good to have a Dutch based DNS provider. TransIP does offer an API for DNS too.

Here their example https://api.transip.nl/rest/docs.html#domains-dns-post :

curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer [your JSON web token]" \
-d '
  {  "dnsEntry": {    
    "name": "www",    
    "expire": 86400,    
    "type": "A",    
    "content": "127.0.0.1"  
  }
} 
' \

https://api.transip.nl/v6/domains/example.com/dns

here a somewhat adjusted one with acme challenge:

POST /domains/example.com/dns

curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer [your JSON web token]" \
-d '
  {  "dnsEntry": {    
    "name": "_acme-challenge.domain",    
    "expire": 86400,    
    "type": "txt",    
    "content": "key"  
  }
} 
' \

And here a Docker implementation example where ini file has bearer token and customer username https://github.com/hsmade/certbot-dns-transip
