This n8n workflow automates the process of obtaining long-lived Facebook User and Page access tokens, which are essential for sustained integrations and automation with Facebook’s API. It is triggered manually, making it ideal for testers and developers who need to refresh tokens on demand. The workflow starts with a manual trigger, followed by setting critical Facebook API parameters such as client ID, client secret, user access token, and optionally, an app-scoped user ID. These parameters are utilized in HTTP requests to Facebook’s OAuth endpoint to exchange short-lived tokens for long-lived ones.
The first node constructs a request to Facebook’s OAuth endpoint, exchanging the provided user access token for a long-lived token. Once obtained, the second HTTP request retrieves the Facebook Pages associated with the user account by using the long-lived user token. This helps fetch the Page access tokens, enabling further automation tasks like posting or analytical tracking.
A sticky note is included for developers to understand the required Facebook parameters and the links to Facebook developer documentation for reference. The ‘Set Parameter’ node allows easy input of Facebook credentials within the workflow.
This workflow is particularly useful for social media managers, developers, or marketers seeking to automate Facebook Page management without manual token refreshes, ensuring continuous access and smoother integration processes.
