Send Invoice PDF - Personalize WhatsApp, Email and SMS template
Whautomate provides these default templates when you send invoice PDFs through WhatsApp, Email or SMS. You can customize these default message templates to cater for your needs and branding.
Step 1: Go to Settings and, under Messaging & Inbox, click Default Communication Templates.

Step 2: On this page, you can access all default communication templates. Find the INVOICE_SEND_PDF templates for WhatsApp, Email and SMS (search for the name, or pick a channel in All Channels), then click the Edit icon to change one.
WhatsApp template
- Click the Edit icon on the WHATSAPP row.
- Under Message Template, keep the default whauto_invoice_pdf_message(en) or pick another approved template. To use your own wording, click Create New Template, submit a template for approval and pick it here once it is approved.
- Fill in the Body Parameters and URL Parameters. Type # or click { } under a parameter to insert a personalisation variable, for example {{client.name}} or {{invoice.number}}. The preview on the right shows the message.
- Click Save.
