CrewAI

This guide explains how to use Integry with CrewAI to post a message on Slack.

1. Install Required Libraries

First, you need to install the necessary packages:

Integry requires Python version 3.12 or higher

• Integry is used to integrate structured tools and functions.

• CrewAI integrate tools and automate workflows using large language models.

pip install integry crewai

2. Initialize Integry & Agent

Import the necessary Libraries

import os
from integry import Integry
from crewai import Agent, Task, Crew, LLM
from crewai.tools.structured_tool import CrewStructuredTool

User-ID is a unique string identifier for a user in your app or agent. Function Calls and Integrations are associated to a user ID. It will be the email address you used during the signup process on Integry.

For example:

user_id = "[e-mail]"

Below code snippet initializes the Integry class to interact with the Integry API using the App-Key and App-Secret.

You can view and copy your App-Key and App-Secret from the Workspace Settings.

Workspace Setting

integry = Integry(
    app_key=os.environ.get("INTEGRY_APP_KEY"),
    app_secret=os.environ.get("INTEGRY_APP_SECRET"),
)

Now initializing the instance of the ChatOpenAI class to interact with OpenAI's GPT-4o model. You can get the API Key from the OpenAI Platform

llm = LLM(
    model="gpt-4o",
    temperature=0,
    base_url="https://api.openai.com/v1",
    api_key=os.environ.get("OPENAI_API_KEY"),
)

3. Initialize Agent with an Integry Function as a Tool

Perfect! Before you can use the functions available in Integry, you need to add the app to Integry. Slack, however, is pre-added to Integry by default, so there’s no need to add it manually.

Now that we've set everything up, we will proceed to send a message in Slack using the slack-post-message function from Integry. You can copy the function ID from the dropdown.

For example

In this case the function ID is slack-post-message

After getting the function ID, we then registers it with the Crew AI agents to enable the assistant to call the function.

slack_post_message = await integry.functions.get("slack-post-message", user_id)

tools = [
    slack_post_message.get_langchain_tool(CrewStructuredTool.from_function, user_id)
]

crewai_agent = Agent(
    role="Integration Assistant",
    goal="Help users achieve their goal by performing their required task in various apps",
    backstory="You are a virtual assistant with access to various apps and services. You are known for your ability to connect to any app and perform any task.",
    verbose=True,
    tools=tools,
    llm=llm,
)

4. Connect Your Slack Account

To allow the agent to send a message on Slack on your user's behalf, the user must connect their Slack account. To connect a Slack account against the provided user ID, execute the following snippet.

slack = await integry.apps.get("slack", user_id)
print(slack.login_url)

This will print a URL which can be opened in a web browser to connect Slack.

5. Execute Agent

This will execute the agent and send a Hello from crewai to the team message in the Slack random channel.

task = Task(
    description="Say hello from crewai to my team on slack in #random channel.",
    agent=crewai_agent,
    expected_output="Result of the task",
)

crew = Crew(agents=[crewai_agent], tasks=[task])

result = crew.kickoff()
