So I either need to bypass send_request and use url_open or patch send_request to be able to amend the authorization header with a custom entry. > What do you think? You *will* have to use send_request, because it implements so much. For example using an upstream proxy. If you omit that, your provider won’t function for those users and that would just be weird and hard to debug. Then, send_request does not require you to use HTTP Basic authentication. It will do it for you if you pass the appropriate parameters, but you don’t have to do that. If you need to pass any additional headers, there is nothing wrong with extending the function and having it take a dictionary with any additional headers. That should be a single commit, please. -Michael > kind regards > Costas > > On Thu, Mar 16, 2023 at 9:53 AM Costas Tyfoxylos <costas.tyf(a)gmail.com> wrote: > Hi Michael, > > Thanks for all the points, they all make sense, I made this patch looking at other implementations of providers so I guess some of the topics you raise are there for more of them.

Hello Costas, Thank you for your response, but please make sure to keep the list copied. > On 16 Mar 2023, at 08:53, Costas Tyfoxylos <costas.tyf(a)gmail.com> wrote: > > Hi Michael, > > Thanks for all the points, they all make sense, I made this patch looking at other implementations of providers so I guess some of the topics you raise are there for more of them.

I am not keen on f-strings as they might not be safe to use: https://bugs.python.org/issue46200 Therefore, I am not indenting to use them in any (sub-)project in an around IPFire.

Hi, please find attached a patch for adding godaddy support to the dynamic dns settings of ipfire. Please let me know if there is anything else I need to do. The current patch has been tested on my local installation with a personal domain and seems to work as expected. kind regards Costas
