Formatting/Variable Errors – Issues with placeholders?

If you're facing Formatting/Variable Errors in your WhatsApp Template, follow these fixes:

---

✅ 1. Use Correct Placeholder Format

• WhatsApp only supports placeholders in {{number}} format.

• Example: Hello {{1}}, your order #{{2}} is confirmed!

• ❌ Avoid special characters: Hello [name], your order is confirmed! → Incorrect

---

🚫 2. No Extra Spaces or Line Breaks

• Do not add extra spaces before or after placeholders.

• Example:

  • ✅ Correct: Hi {{1}}, your payment of {{2}} is received.

  • ❌ Incorrect: Hi {{ 1 }}, your payment of {{ 2 }} is received.

---

📌 3. Ensure Variables are Properly Mapped

• If sending via API, ensure the values match the placeholders.

• Example API JSON:

  jsonCopyEdit{
    "name": "order_update",
    "language": "en",
    "components": [
      {
        "type": "body",
        "parameters": [
          { "type": "text", "text": "John" },
          { "type": "text", "text": "₹500" }
        ]
      }
    ]
  }

• Mismatched variables → Template fails to send.

---

🔄 4. Avoid Incorrect Data Types

• If using media placeholders, ensure the correct type is used.

• Example:

  • ✅ Text: {{1}} = John Doe

  • ✅ Image URL: {{1}} = https://image-link.com/sample.jpg

  • ❌ Sending text in a media placeholder

---

🛠 5. Keep Template Language & Placeholders Consistent

• Ensure template language matches the variables.

• Example:

  • ✅ English Template: Hello {{1}}, your OTP is {{2}}.

  • ❌ English Template + Hindi Variables: Hello {{1}}, आपका OTP है {{2}}। → May get rejected

---

🔥 6. Test with a Sample Number

• Send a test message using WhatsApp Manager or API Sandbox to check formatting.

---

🆘 7. Check Meta Business API Logs

• If using API, check response logs for errors like:

  • 470 – Invalid Parameter Format

  • 1006 – Template not found

  • 131026 – Missing or incorrect variables
