WhatsApp Error 132007: Template Format Invalid — Component Fix Guide

Error 132007 indicates an invalid JSON component structure, such as referencing an index that does not exist or passing header parameters to a text-only header.

Probable Causes

Passing button parameters with index 1 when the template only has one button at index 0
Mismatched header component types (e.g. passing image URL to a video header)
Missing sub_type property for dynamic URL buttons

Step-by-Step Resolution

Recommended Fix Protocol:

Ensure button indexes are 0-based. If passing dynamic URL parameters, specify sub_type: url and index: 0 matching the exact button placement in your template.

Technical Example / Code Payload:

{ "type": "button", "sub_type": "url", "index": "0", "parameters": [{"type": "text", "text": "tracking-code-123"}] }
