HTTPosion request format

I have the following in python:

response =,data=parameters, auth=(api_key, ‘’))

What is the HTTPoison ot HTTPotion equivalent for this.

Please do not assume that anyone does know what a certain snippet in a foreign language does. Please try to explain how the request should look like.


Have you looked at the documentation?

Here’s the post function:

Something along these lines is what you want to do:

case, body, headers) do
  {:ok, response} -> IO.inspect(response) # Request went through, do something :)
  {:error, reason} -> IO.inspect(reason) # Request failed...

HTTPoison is cool but take a look at Tesla also.



@Linuus have looked at a lot of online resources and have tried various formats/syntax, but couldn’t successfully get a response from server…

Can you help me with this:, body, headers) —> body should contain the data - (should i use Poison.encode!(mydata) )

and the authentication key and password… should it be a part of headers??

In ruby I have the Unirest library with post function something like url, auth: {:user => $api_key, :password => ‘’}, parameters: parameters

@NobbZ Sorry for the lack of clarity - I assumed that many would be comfortable relating to my question if gave the python analogy.

Even if elixir a language, that has adopted his community from a lot of other languages, most of us will probably have a ruby background. But of course, everyone here should be able to read code in a couple of languages, but beeing able to read that language does not mean knowing that languages stdlib or its various libraries available. So whenever you are giving an example in an foreign language you should give a link to the documentation of the functions/methods used.

As far as I can tell from the tests, you can use HTTP Basic Auth, by simply giving [hackney: [basic_auth: {"user", "pass"}]] as an option to any <method>/4 call.

A quick search for “basic auth” against the github repo offers this in search results:

Its been a while since I’ve written my answer, but thats probably what I meant when I wrote “as far as I can tell from the tests” :wink:

HTTPoison POST Example. Auth goes into the trailing options.
post!(url, body, headers \\ [], options \\ [])

iex(7)> {code, response} = "", "grant_type=client_credentials", [{"Content-Type",  "application/x-www-form-urlencoded"}], [hackney: [basic_auth: {"user", "password"}] ]

The code is :ok, or not. The response will be an %HTTPoison.Response

HTTPotion POST Example. Most everything, including auth, goes into options.
response =, options \\ [])

iex(2)> options =  [body: "grant_type=client_credentials",
     headers: ["Content-Type": "application/x-www-form-urlencoded"],
     basic_auth: {"user","password"}]
iex(3)>response ="", options)

The response will be an %HTTPotion.Response.

Docs are easily found with a search. Between the docs you find and the above examples, you should be set!
