What is the correct way to use parameters in the MyOperator app for WhatsApp templates?

Quick answer


Use double-brace placeholders — {{1}}, {{2}}, {{3}} — in your template body (and header text/button URLs if needed). Provide matching sample values in square brackets when submitting the template, then map each column from your Excel/CSV file to the placeholders during campaign setup. Parameters are not allowed in the footer.


When should I use this guide?


Use it right before you create or submit a WhatsApp Template Message that requires personalisation (names, order IDs, dates) so you avoid Meta rejections and blank variables.



1. What parameters are


  • Written as {{1}}, {{2}}, {{3}} (variables/placeholders)
  • Replaced with real values pulled from your Excel/CSV audience file at send-time.
  • Sample values are mandatory for Meta review.



2. Step-by-step: add parameters to a template


  1. Login to MyOperator Panel → Go to WhatsApp → Templates → Create New Template.


  1. Insert parameters where you need personalisation.


  1. ✅ Correct: Hello {{1}}, Enjoy an exclusive {{2}} discount on your next purchase with us! Renew Before {{3}}


  1. ❌ Incorrect: Hello {1}, Enjoy an exclusive 2 discount on your next purchase with us! Renew Before 3.



Alt text: Sample parameter insertion in the template


  1. In the Sample Message, replace each variable with a realistic placeholder in square brackets.


Example: Hello [John], your order [#12345] is out for delivery.


  1. Please submit the template; the Meta review requires both the template format and a sample value.

4. Approval rules & restrictions


  • Parameters allowed only in:
  • Header (text only)
  • Body
  • Buttons (URL query strings, CTA labels)


  • Not allowed in the footer.


  • Must appear sequentially ({{1}}, {{2}}, {{3}}… no skipping).


  • Every parameter in the template format must have a sample value.



5. Best-practices checklist


  • ✔ Provide clear sample values [Priya], [Order #12345].
  • ✔ Keep messages conversational; avoid robotic tone.
  • ✔ Preview the template before submission.
  • ✔ Use fallback values during campaign mapping (e.g., “Customer” if name missing).
  • ✔ Limit the number of parameters; too many may be rejected for poor user experience.



6. Summary


  • Parameters personalise messages and are required for certain template approvals.
  • Define them with {{n}} and supply sample values in [ ].
  • Follow Meta’s rules: sequential numbering, no parameters in footers, and provide matching samples to avoid rejection.
