WhatsApp template builder now catches invalid variables before you save

The Create WhatsApp Template Builder with Inline Variable Validation

> No more saving a template, waiting, and getting a WhatsApp rejection you have to decode. Bad variables are flagged immediately, right in the builder.

• Start and end variable check:

  WhatsApp rejects a message body that begins or ends with a variable. The builder now flags it and blocks save until there is text around the variable, instead of letting you save something that will be rejected later.

• Invalid variable detection in header and body:

  Only numbered placeholders (

  {{1}}

  ,

  {{2}}

  , and so on) are valid. Broken tokens like

  {{1$}}

  and unbalanced or extra braces (

  {{1

  ,

  {{1}}}

  ) are now caught immediately, with guidance to the correct format.

• Reputation review-request preset fixed:

  The default reputation template used to end in a trailing variable, which trips the rule above. It has been cleaned up so new reputation templates pass validation with no manual edits.

Create Template is one of the most-used WhatsApp surfaces, and a template rejected by WhatsApp after you save is pure wasted effort: you have to guess what WhatsApp did not like and retry. Catching variable mistakes inline turns a delayed, opaque rejection into a clear, immediate fix, so templates go live faster and generate less support confusion on a core messaging surface.

• Get templates right on the first try, with no post-save rejection round-trips
• Faster template setup on a surface agencies use constantly
• Fewer support tickets from confusing WhatsApp rejections
