New Features

files.upload v2 in WebClient / AsyncWebClient

We've received many reports on the performance issue of the existing files.upload API (refer to #1191 #1165 for details). So, to cope with the problem, our platform team decided to unlock a new way to upload files to Slack via public APIs. To utilize the new approach, developers need to implement the following steps on their code side:

1. Call WebClient#files_getUploadURLExternal() method to receive a URL to use for each file
2. Perform an HTTP POST request to the URL you received in step 1 for each file
3. Call WebClient#files_completeUploadExternal() method with the pairs of file ID and title to complete the whole process, plus share the files in a channel
4. If you need the full metadata of the files, call WebClient#files_info() method for each file

We do understand that writing the above code requires many lines of code. Also, the existing WebClient#files_upload() users have to take a certain amount of time for migration. To mitigate the pain, we've added a wrapper method named WebClient#files_upload_v2() on the SDK side.

Also, in addition to the performance improvements, another good news is that 3rd party apps can now upload multiple files at a time!

See the following code examples demonstrating how the wrapper method works:

import os
from slack_sdk import WebClient
client = WebClient(token=os.environ["SLACK_BOT_TOKEN"])
Legacy way
response = client.files_upload(
file="./logo.png",
title="New company logo",
channels=["C12345"],
initial_comment="Here is the latest version of our new company logo :wave:",
)
response.get("file")  # returns the full metadata of the uploaded file
New way - the same parameters works in most cases
response = client.files_upload_v2(
file="./logo.png",
title="New company logo",
# Note that channels still works but going with channel="C12345" is recommended
# channels=["C111", "C222"] is no longer supported. In this case, an exception can be thrown
channels=["C12345"],
initial_comment="Here is the latest version of our new company logo :wave:",
)
response.get("file")  # returns the full metadata of the uploaded file
</tr></table>
