Messages fire via WasenderAPI, rigorously logged as 'Outbound' in Baserow. Gain total control, drive proven results.\n\n**Who's it for**\nFor teams aiming to dominate outbound WhatsApp and centralize Baserow logging. Serious about communication efficiency? This is your solution.\n\n**Setup Steps**\nRapid implementation. Your action plan:\n1.  Activate all critical workflow nodes (`Sent_whatsapp`, `Switch`, `send_message`, `Update_imsg`, `fallback`).\n2.  Copy `Sent_whatsapp` webhook URL. Configure Baserow automation to trigger webhook on 'Sent' status update.\n3.  Ensure Baserow 'Messages' table has 'Status' ('Sent' option), linked 'WhatsApp Number' (from 'Contacts'), and 'Message Content' fields. (Optional: Use [Baserow Message Form](https://baserow.io/form/B2TUPV0S_Fx3PKyNiKOQR4YAdo77RnvAxZyMw8jN7Uc) for input).\n4.  Embed WasenderAPI and Baserow API tokens in n8n Credentials. No compromise on security.\n\n**Requirements**\n* Active n8n instance (self-hosted/cloud).\n* WasenderAPI.com trial/subscription.\n* Baserow account with pre-configured 'Contacts' ([link](https://baserow.io/public/grid/a5iWkAQpu8QljUlgwgm_pour_Au5BKd3mtkfu-B6N7Y)) and 'Messages' ([link](https://baserow.io/public/grid/0H22XZitFDWnrVNnKwBfiI7M6XX5CugHrXHEzdCY4xY)) tables.\n\n**How to customize the workflow**\nCustomize operations: Verify `send_message` and `Update_imsg` node field mappings with Baserow table IDs/names. Precision drives performance.\n\n**Note:** Crucial: Maintain the exact flow layout. This guarantees optimal performance and correct order of operations."
