I started writing a Slack bot in Python and came to a halt when I couldn't find a way to send richly-formatted messages using the either of the two methods:
sc.rtm_send_message("channel_name", my_message)
sc.api_call("chat.postMessage", channel="channel_name", text=my_message, username="username", icon_url="icon_url")
where my_message = json.dumps({'attachments': [{...}]})
I now know that I can do this using the webhook approach but is it possible with the above method?
I found out where I was going wrong.
I was passing my message to the wrong argument in the sc.api_call
method.
I should've been passing it to sc.api_call(
attachments=
...)
argument, not the text
argument.
