Steps to connect to Slack via Agenthost
Create an Agenthost account
If you don't have an account, create one by clicking the "Sign Up" button on the Agenthost homepage. They have a free tier so no need to worry about paying.
Create or import your Assistant
In your workspace you can create a new assistant from scratch or import an existing assistant from OpenAI. Please note that assistants are not the same as Assistants. If you're new to assistants or Agents, we recommend starting with a blank agent or creating a website chatbot and using the default settings.
Link your Agent to Slack
Now that your agent is created, you can easily link it through Agenthost by going to Custom Actions. Then select the specific actions from Slack that you want your agent to use then go to the chat page to test it out!
Activate your Agent based on Slack triggers
If you want your agent to be able to activate when something happens in Slack, you can use the following triggers and use the Agenthost Create Message action to send a message to your agent.

Option 2: Creating a Custom Assistant Action (For Advanced Customization)
For those seeking more granular control over their OpenAI Assistant's interaction with Slack, creating a custom Assistant action provides a powerful, albeit more complex, solution.
Steps to Create a Custom Assistant Action:
- Understand API authentication: Many apps, including Slack, require OAuth credentials instead of simple API keys
- Study the developer documentation: Familiarize yourself with Slack's API guidelines and authentication process
- Create an OpenAPI schema: Define the endpoints your Assistant will access
- Configure Assistant actions: Add the schema and appropriate credentials to your OpenAI Assistant
While this method requires more technical expertise, it offers unparalleled flexibility in tailoring your Assistant's capabilities to your specific needs. Once set up, your Assistant can make direct API calls to Slack, opening up a world of advanced automation and interaction possibilities.
Choosing the Right Integration Method for You
When deciding between Agenthost and custom Assistant actions for integrating your OpenAI Assistant with Slack, consider the following factors:
- Technical expertise: Agenthost is ideal for non-coders, while custom actions suit those comfortable with API integration
- Time constraints: Agenthost offers rapid setup, whereas custom actions require more development time
- Customization needs: Custom actions provide more flexibility, while Agenthost offers a balance of ease and functionality
- Scale of integration: Consider the number of apps you need to connect and the complexity of your workflows
Both methods have their strengths, and the best choice depends on your specific requirements, resources, and long-term goals for AI integration.
