WHATSAPP n8n INTEGRATION: AUTOMATE WHATSAPP WITH N8N

The Send message action is your go-to for programmatic WhatsApp communication. It allows you to send text messages to any WhatsApp user who has opted into receiving messages from your business—perfect for notifications, updates, and conversational responses.

Key parameters: Credential to connect with (required dropdown to select your authenticated WhatsApp account), Resource (set to "Message" to work with WhatsApp messages), Operation (set to "Send" to dispatch a message), Sender Phone Number (or ID) (optional text field to specify which business phone number sends the message, useful if you have multiple numbers), Recipient's Phone Number (required field where you enter the destination number including country code, e.g., +33612345678), Message Type (dropdown to select the content type—"Text" for plain text messages), Text Body (the actual message content you want to send), and Additional Fields (optional section for extra customization).

Use cases: Send order confirmation messages when a purchase is completed, notify customers about delivery status updates in real-time, and reply automatically to incoming inquiries during off-hours.

The Send template action lets you send pre-approved message templates through WhatsApp. Templates are required by WhatsApp's policy for initiating conversations with customers—they ensure compliance and enable business-initiated outreach for notifications, alerts, and marketing.

Key parameters: Credential to connect with (select your WhatsApp OAuth credentials), Resource (set to "Message" for messaging operations), Operation (set to "Send Template" to use a pre-approved template), Sender Phone Number (or ID) (specify the sending phone number), Recipient's Phone Number (the customer's phone number with country code), Template (enter the template name or ID as registered in your WhatsApp Business Manager), and Components (add dynamic components like text variables, headers, or media to personalize the template).

Use cases: Send appointment reminders with date/time variables filled dynamically, dispatch shipping notifications with tracking numbers, and send payment confirmation messages with order details.

This powerful action combines sending a message with synchronous response handling. Your workflow pauses after sending and resumes only when the recipient replies—enabling true conversational automations and approval workflows directly in WhatsApp.

Key parameters: Credential to connect with (your WhatsApp account credentials), Sender Phone Number (or ID) (the business number sending the message), Recipient's Phone Number (where to send the message), Message (the text content of your outgoing message), Response Type (dropdown to define expected response format—"Approval" expects yes/no type responses), Approval Options (configure specific response options the recipient can choose from), and Options (additional configuration for timeout handling and advanced behaviors).

Use cases: Build approval workflows where managers confirm requests via WhatsApp, create interactive surveys that wait for each response before proceeding, and design chatbot conversations with branching logic based on user replies. You can also combine this with OpenAI integration to create intelligent conversational bots.

The Upload media action enables you to upload files to WhatsApp's servers, making them available to send in messages. This is essential for sharing images, documents, videos, or audio files with your customers programmatically.

Key parameters: Credential to connect with (required authentication credential), Resource (set to "Media" for file operations), Operation (set to "Upload" to send files to WhatsApp), Sender Phone Number (or ID) (optional field to specify the associated phone number), Property Name (required text field specifying which data property contains the media file—default is "data"), and Additional Fields (optional configurations for advanced upload scenarios).

Use cases: Upload product images from your catalog to send in customer conversations, share PDF invoices or receipts automatically after purchases, and send audio messages or video tutorials to customers.

The Download media action retrieves media files that customers have shared with you via WhatsApp. When someone sends a photo, document, or voice message, you can automatically download it for processing, storage, or analysis.

Key parameters: Credential to connect with (select your WhatsApp authentication), Resource (set to "Media" for file operations), Operation (set to "Download" to retrieve files), and Media ID (required text field where you enter the unique identifier of the media to download—typically obtained from a preceding WhatsApp Trigger that captured an incoming message with media).

Use cases: Automatically save customer-submitted photos to Dropbox or cloud storage, process ID documents shared for verification workflows, and archive voice messages by transcribing and storing them.

The Delete media action removes previously uploaded media from WhatsApp's servers. This is useful for cleaning up after automated processes, managing storage, or ensuring sensitive documents don't persist longer than necessary.

Key parameters: Credential to connect with (your WhatsApp account credentials), Resource (set to "Media" for file operations), Operation (set to "Delete" to remove the file), and Media ID (required field containing the unique identifier of the media to delete).

Use cases: Clean up temporary media after it's been processed and stored elsewhere, remove sensitive documents after a verification workflow completes, and implement data retention policies by deleting old media automatically. For troubleshooting workflow issues, check our n8n troubleshooting guide.
