Hi, I'm very glad I came across this vibrant community of people developing AI Agents and automations. There are many examples of how one can build an AI Agent or even use multiple AI Agents to achieve great automations when they are deployed and used by the developer himself/herself. Specifically, when we try to automate Social Media posts and interactions, we use our own credentials and set up OAuth2 integration between those Social Media systems and our n8n workflow. But what about letting someone else use the deployed workflow with their own Social Media or other system credentials? Imagine you design a workflow to sell to users, the workflow can be deployed when the user completes a payment, and then the user should just authorise the workflow for Social Media (Twitter, LinkedIn, etc.) for the workflow to start posting and responding on the user's behalf. I think that OAuth2 authorization is also required by many services to allow the n8n workflow to perform activities on the user's behalf, for example sending Gmail messages, updating Google Docs Sheet etc. How to request the user to Authorize the workflow with their own credentials to allow the workflow to perform activities on the user's behalf when a workflow is deployed and can be used by any user that is granted access to it? Are there any examples of such workflows/templates/YT tutorials that you can share or refer to? Thank you very much.
