Errors

template_param_mismatch

The template parameters do not match the approved template

A Cloud template is approved with a fixed number of placeholders in a fixed order. Sending a different count, or the wrong types, is refused before anything is delivered.

What to do

Compare what you sent against the template as approved in Meta's manager. The message text carries Meta's own detail about which parameter was wrong.
