WhatsApp error 132007: Template Format Character Policy Violated

Code 132007 means the message, as assembled with your parameter values, violates a WhatsApp formatting or content policy and was refused at send time. The official description is broad, but the title names the usual mechanism: a format character policy. Template parameters may not contain newlines, tabs, or more than four consecutive spaces, and values that include them trigger 132007 even though the template itself was approved. The check runs on the hydrated message, so a template that works for most recipients can fail for one whose data contains a line break.

Less commonly the code reflects a content policy issue with the parameter values themselves, such as text that turns an approved template into something prohibited. Meta's solution text points at the rejection reasons documentation for the possible violations.

The template's approval status is not in question and the parameter count is correct; the problem is inside the values.

Run every parameter value through a sanitizer that removes newlines, tabs, control characters, and excess spaces before it reaches the template builder, and unit-test it with real exports. Keep templates' variable slots for short, predictable data and move free text into service-window messages where formatting rules are looser. Run values and copy through the template checker; repeated policy hits on delivered content eventually show up as quality problems (132015).
