WhatsApp Error 132005: Template Variable Value Missing — Fix

Error 132005 occurs when a parameter object is included in your payload but the text property is empty, null, or consists solely of whitespace characters.

Probable Causes

CRM database field is null and evaluates to empty string in JSON payload
Variable text value contains only spaces or newline characters
Dynamic button URL variable is blank

Step-by-Step Resolution

Recommended Fix Protocol:

Implement null-coalescing fallbacks in your code before creating the payload: sanitize values so that empty or null fields default to a friendly fallback string rather than empty quotes.

Technical Example / Code Payload:

// Sanitization Example $cleanText = !empty($val) ? trim((string)$val) : 'Customer';
