Slack Integration via API Token

I’m curious if anyone out there has built a Slack integration that uses an API Token for access rather than OAuth?  For reasons that I do not understand, the built in Slack integration only supports OAuth, which means it ends up tied to a specific user.  It seems silly to rebuild identical functionality simply to have a different authentication method.

If there are others whose security team would like this feature, perhaps you can chime in and help get Zapier to prioritize providing this?

Yes, I've built a Slack integration that uses an API Token for access instead of OAuth. It's a straightforward process, and it's particularly useful for automated tasks or internal tools where user authentication isn't necessary. API integration meaning. Here's a high-level overview of what you need to do:

  1. Generate an API Token: First, you'll need to generate an API Token for your Slack app. You can do this in the Slack API portal or by creating a new Slack app and obtaining a token through their developer dashboard.
  2. Scope Permissions: Depending on what your integration needs to do, you'll need to select the appropriate permissions when generating the API Token. Make sure it has the necessary scopes to perform the actions you require.
  3. Implement API Calls: You can use various programming languages and libraries to make API calls to Slack using this token. For example, you can use the Slack API client for your preferred programming language (Python, Node.js, etc.) or make HTTP requests directly.
  4. Authentication: When making API calls, you'll typically include the API Token in the Authorization header of your HTTP request. It's essential to keep this token secure, as it grants access to your Slack workspace.
  5. Handling Responses: Handle the responses from Slack's API as needed for your integration. Slack's API documentation provides details on how to structure requests and interpret responses.
  6. Error Handling and Rate Limiting: Be sure to implement error handling and respect Slack's rate limiting to ensure the reliability and performance of your integration.

Here's a basic example using Python and the requests library to post a message to a Slack channel:

import requests

import requests

api_token = 'YOUR_API_TOKEN'
channel_id = 'YOUR_CHANNEL_ID'
message = 'Hello, Slack!'

headers = {
'Authorization': f'Bearer {api_token}'

payload = {
'channel': channel_id,
'text': message

response ='', headers=headers, json=payload)

if response.status_code == 200:
print('Message posted successfully!')
print(f'Error: {response.status_code}, {response.text}')

Remember to replace 'YOUR_API_TOKEN' and 'YOUR_CHANNEL_ID' with your actual API token and channel ID. This is just a simple example to get you started.

Let me know if you have any specific questions or need further assistance with your Slack integration!

If you’re implementing all of the api calls, what value does Zapier provide?
