Modified Zender WhatsApp API Node for n8n

This is a modified version of the original @umairabubakkar/n8n-nodes-zender package. The main enhancement is making the Account ID configurable as an independent parameter instead of being tied to credentials.

Changes Made

• Independent Account ID: Account ID is now a separate input parameter that can be configured for operations that require it
• Smart Display: Account ID field only appears for operations that actually need it (not for general operations like "Get All Accounts")
• Flexible Configuration: You can now use different Account IDs for different operations within the same workflow
• Simplified Credentials: Credentials now only contain API Secret and Base URL
• Improved UI: Optional parameters are now grouped in "Additional Fields" sections for cleaner forms
• Contact Management: Full CRUD operations for contacts and contact groups
• OTP Operations: Send OTP via SMS or WhatsApp with configurable parameters
• SMS Operations: Send SMS and bulk SMS with device/credit modes
• Proper File Upload: Binary file support with multipart/form-data for documents and media

Operations That Require Account ID

• Message Operations: Send and Send Bulk
• Account Operations: Relink and Delete (but NOT Get All, Link, Get QR Info, Get QR Image)
• Group Operations: Get All Groups and Get Contacts
• Validation: Validate Phone Number

Operations That DON'T Require Account ID

• Chat Operations: All chat operations (Get Received, Sent, Pending, Single, Delete)
• Campaign Operations: All campaign operations
• Server Operations: Get All Servers
• Account Operations: Get All, Link, Get QR Info, Get QR Image

Or install via n8n community nodes:
