To post on a Page, you need a **Page Token**.\n   - Send a GET request to the following endpoint (replace `{user-access-token}` with your User Token):\n     ```\n     GET https://graph.facebook.com/v21.0/me/accounts?access_token={user-access-token}\n     ```\n   - The response will include a list of Pages you manage along with their corresponding **Page Tokens**.\n\n3. **Use the Page Token**:\n   - Use the **Page Token** to perform actions such as posting, managing comments, or other tasks on the Page.\n\n**Note**:\n- Ensure the User Token has the necessary permissions like `pages_manage_posts`, `pages_read_engagement`, etc., to retrieve the Page Token.\n- The Page Token will have the same expiration as the User Token (approximately 60 days) and can be renewed.\n\n\n`https://github.com/luuhung93/n8n-json`"},"typeVersion":1},{"id":"4af7f1f6-9479-4489-9282-7083cd29649c","name":"Redirect URL","type":"n8n-nodes-base.code","position":[2980,480],"parameters":{"jsCode":"const config = $('Config').first().json;\n\n\nconst generateRandomState = () => {\n\treturn Math.random().toString(36).substring(2, 15) +\n\t\tMath.random().toString(36).substring(2, 15);\n}\nconst state = generateRandomState();\n\nconst correctScopes = [\n        'publish_video',\n\t\t'pages_show_list',\n\t\t'business_management',\n        'pages_read_engagement',\n        'pages_read_user_content',\n        'pages_manage_metadata',\n        'pages_manage_posts',\n        'pages_manage_engagement',\n\t];\n\nconst authUrl = `https://www.facebook.com/v22.0/dialog/oauth?client_id=${config.app_id}&redirect_uri=${config.fb_redirect_uri}&scope=${correctScopes.join(',')}&response_type=code&state=${state}`;\n\nreturn [{\n  authUrl\n}];"},"typeVersion":2},{"id":"b415e387-17ed-4451-ae7d-b8d1fdf8ee06","name":"Redirect","type":"n8n-nodes-base.respondToWebhook","position":[3740,480],"parameters":{"options":{},"redirectURL":"={{ $json.authUrl }}","respondWith":"redirect"},"typeVersion":1.1},{"id":"d59290d9-79b5-4212-a8ad-a1a9e074bbf2","name":"Sticky Note1","type":"n8n-nodes-base.stickyNote","position":[1840,140],"parameters":{"width":420,"height":480,"content":"Edit:\n - fb_redirect_uri\n - app_id\n - app_secret\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nGo to the [Facebook App](https://developers.facebook.com/apps/).\n    - Select **Facebook Login** from the left-hand menu.\n    - Click on **Settings**.\n    - In the **Valid OAuth Redirect URIs** section, add the URL (fb_redirect_uri): `https://localhost:5678/webhook/facebook-login`"},"typeVersion":1},{"id":"952f17fa-efdf-4523-9d9b-ff071670e425","name":"Sticky Note2","type":"n8n-nodes-base.stickyNote","position":[2460,460],"parameters":{"width":640,"height":760,"content":"\n\n\n\n### Guide to Editing `correctScopes`\n\n1. **Add a Permission**:\n   - Add the permission to the `correctScopes` array.

For example:\n     ```javascript\n     const correctScopes = [\n       'pages_manage_posts', // Keep this permission\n       // 'pages_messaging',  // Remove this permission\n     ];\n     ```\n\n4. **View Available Permissions**:\n   - Refer to the full list of permissions at [Facebook Permissions](https://developers.facebook.com/docs/permissions/).\n\nSimply edit the `correctScopes` array; no need to worry about other parts.\n"},"typeVersion":1},{"id":"dbc712ba-1a95-4041-ac27-824d804726bc","name":"Token","type":"n8n-nodes-base.respondToWebhook","position":[3700,-100],"parameters":{"options":{},"respondWith":"text","responseBody":"={{ $json.access_token }}"},"typeVersion":1.1},{"id":"560d3c3f-a0e8-432e-904f-71cd7525fd0d","name":"Sticky Note3","type":"n8n-nodes-base.stickyNote","position":[3280,-180],"parameters":{"width":280,"content":"By default, the token will be displayed on the screen.
