WhatsApp Error 132000: Template Parameter Count Mismatch — Fix Guide
Error 132000 occurs when the number of variable parameters passed in your API payload does not match the exact number of {{1}}, {{2}} placeholders defined in your approved Meta template.
Step-by-Step Resolution
Recommended Fix Protocol:
Inspect the approved template definition in Meta WhatsApp Manager. Count the total variables in the body, header, and button. Ensure your API payload JSON contains precisely the same count of parameter objects in matching sequence.

"type": "body",
"parameters": [
{"type": "text", "text": "Rahul Sharma"},
{"type": "text", "text": "Order #9201"}
]
}
Quick Answers
Frequently Asked Questions
What happens if a customer name is null?+
Pass a fallback string (such as Valued Customer) rather than an empty or omitted parameter object to avoid triggering Error 132000.
Can I change variable counts on an approved template?+
