On the oauth.access method, the docs say:

We strongly recommend supplying the Client ID and Client Secret using the HTTP Basic authentication scheme, as discussed in RFC 6749.

It could be good to do this instead of providing them in the URL parameters, I think?

So the new uploads endpoint works fine when posting snippets of text, but it won't upload binary files like images. I'm gonna PR an improved version soon.

Since everything is sent through URL params, trying to send String's containing spaces raises an not-so-related StringReader NullPointerException. This means to send strings, users need to UrlEncode them before sending.

I believe this should be handled by the library or mentioned in the doc(string)s.

The example of file upload using a clojure.java.io/input-stream from the readme is broken

Execution error at clojure.data.json/write-generic (json.clj:599).
Don't know how to write JSON of class java.io.BufferedInputStream

seems like it was caused by this commit: 739847b

https://api.slack.com/docs/conversations-api

While using [org.julienxx/clj-slack "0.5.2.1"] getting following compilation error:

(require 'clj-slack.users)

CompilerException java.lang.IllegalArgumentException: Can't define method not in interfaces: meta, compiling:(clj_http/headers.clj:105:1)

Hi,

According to https://api.slack.com/changelog/2020-01-deprecating-antecedents-to-the-conversations-api some API endpoints are retired since 24.02.2021.

How about removing the corresponding namespaces groups, im, mpim and channels?

I couldn't find anything related to timeouts and I think this is a huge opportunity for improvement.
It should be possible (and really encouraged) to specify reasonable timeouts for every slack operation.
Otherwise, the app can freeze indefinitely.

clj-http provides a couple of options for configuring timeouts: https://github.com/dakrone/clj-http#post

• :conn-timeout
• :socket-timeout

There's also :conn-request-timeout but I guess that's not that important since it's a timeout for requesting a connection from connection manager.

There could a default (e.g. 60 seconds) for both timeouts too.

It seems that the auth style used by the library, namely passing token in query params no longer works:

{:error "invalid_auth", :response {:ok false, :error "invalid_auth"}}

You need to pass the token in the Authorization header.
Afaik, the easiest way to do this is to use the :oauth-token param accepted by clj-http.
Here's what I ended up using: curiousprogrammer-net/slack-pom@f998e92#diff-1a6ed93c553296dc723c8009dc2fd60183c5a3c00d4b50b6ca511fbdead178ccR20

It seems like that's what is next in your plate... let me know if you plan to start doing it anytime soon or if I should take a stab at it.

CI and testing against our own slack team would be great. What do you think? I already have one team setup for this project and it's the one I'm using to manually test the library.

Whatever i am trying to do i get an error:

(channels/list connection)
{:ok false, :error "missing_scope", :needed "channels:read", :provided "identify,incoming-webhook"}

Attachments are deprecated, replaced by blocks.

I want to create a slack bot that listens to specific words in a channel and answers to those. From my understanding, I need to use the real-time-messaging API from slack. My problem is, other than creating a session I don't understand how to use it from the docs or the code.

(chat/post-message connection "#logs" "" {
                                            :attachments [{"text" text
                                                           "color" color}]})

Posted as a user who created the app?!

(chat/post-message connection "#logs" "" {:username "Overseer"
                                            :attachments [{"text" text
                                                           "color" color}]})

The same.

(chat/post-message connection "#logs" "" {
                                            :as_username false/true
                                            :attachments [{"text" text
                                                           "color" color}]})

CompilerException java.lang.IllegalArgumentException: Body may not be null, compiling:(.../src/.../slack.clj:27:1)

(chat/post-message connection "#logs" "" {:as_username "Overseer"
                                            :attachments [{"text" text
                                                           "color" color}]})

No errors but posted as a user who created the app.

The goal: i want to post messages as a bot / another user. Whatever but not me :)

Multipart stuff.

Seems like stringily-keys is missing:

PS: I found this issue because the cljdoc documentation build for clj-slack failed (see build).
