Sending HTTP MERGE request HTTPoison

I ran into an interesting issue while working on my #ex_azure_storage library. I want to support Azure Table Storage merge entity operation (ref. Merge Entity (REST API) - Azure Storage | Microsoft Docs).

The spec said the client needs to send HTTP MERGE request, but I don’t HTTPoison method spec does not include :merge.

Is there a way to overwrite HTTPoison request method?

Even though it doesn’t have it in spec - :hackney does
So this works for me

:hackney.request(:merge, url, headers, body)

And apparently HTTPoison just bypasses those params to :hackney - so I was able to make the same request with:

HTTPoison.request(:merge, url, body, headers)

It works indeed :slight_smile: thanks @RudManusachi
