This error usually occurs due to a template issue, and the messages will not be sent and will fail.
The headers added in the template should have placeholders and if they don’t have placeholders and simple plain text is used this error occurs.
Usually we have to remove the header if no place holder is there or you should incorportate a placeholder.
Example Scenario: #
Suppose you have a template like this:
Template name: order_confirmation
Header: "Order Confirmed"
Body: "Hi {{1}}, your order #{{2}} is confirmed."Here:
- Header has no placeholders → expects 0 parameters.
- Body has 2 placeholders → expects 2 parameters.
How to Fix It: #
Option 1:
If your template header doesn’t have a placeholder (like {{1}}), remove the header component from your API request.
Option 2:
If you do want a variable in the header, edit the template in Meta’s WhatsApp Manager to include a placeholder in the header, then re-submit for approval.
