Zapier, a workflow automation software, has integrated ChatGPT with its platform to enable users to create automated workflows that send information between different apps. The integration allows users to create two types of bots: reply bots that respond to specific channel messages and slash command bots that can be triggered from any channel. To set up the integration, users need to create a free OpenAI account, configure their assistant within OpenAI, and then connect it to Zapier. They can then create Zaps using the ChatGPT action and Slack as the trigger app, setting up custom workflows to automate tasks such as answering questions and sending messages. The integration is useful for teams looking to streamline their communication and workflow processes.
