Credentials you'll need
Each integration node will prompt for credentials when you import. We strip credential IDs before publishing — you'll add your own.

How this works
This workflow automates personalised WhatsApp messaging by generating tailored content with AI and dispatching it efficiently, saving hours of manual outreach for businesses or individuals managing customer engagement. It suits marketers, sales teams, or support staff who need to send targeted updates, promotions, or responses without repetitive typing. The core step involves an AI agent powered by OpenAI Chat Model crafting custom messages based on recipient data, followed by seamless delivery via the Evolution API integration, all triggered by events like new Google Drive uploads.
Use this when handling bulk, context-specific WhatsApp communications, such as notifying clients of new offers or following up on inquiries, especially if you already store data in Google Drive. Avoid it for very high-volume sends that might hit API limits or for non-personalised blasts better suited to email tools. Common variations include adapting the AI prompts for different languages or integrating with CRM systems for dynamic recipient lists.
