How to use parameters while creating WhatsApp Template Message?

• Proofread your content for spelling and grammar before submitting it for review. Messages with incorrect spellings or any grammatical errors may prompt customers to view these messages as spam
   
• Make sure to use variable parameters and that they have the correct number of curly brackets (i.e., there need to be 2 brackets on the left and 2 on the right of the variable)
   
• Make sure the parameters (e.g., {{1}}) contains some text with it
  For example:
  Correct Format:
  Hello {{1}}
  
  Wrong Format:
  Hello
  {{1}}
  {{2}}
   
• Make sure the language selected matches the content of your message template
  
• If you select Spanish as the message template language but the content is in English, your message template will be rejected
• Ensure that your content is in one language. A mixture of languages such as "Hinglish" or "Spanglish" will not be approved
   
• If you’re going to submit a message template for testing your API connection, please ensure it’s in the correct format. Any other variation will be rejected
  
• Message template name: test
• Content: Hello {{1}}
   
• Refrain from using a URL shortener for your links (e.g., bit.ly, TinyURL, or goo.gl) because they obscure the intended link destination
   
• The URL domain in your links should belong to your business
   
• Refrain from using extra spaces at the end of your template or double spacing in between your content. Generally, this spacing results in rejection of the message
  
  
• Refrain from adding double line space between your texts. For example;
  Correct Format:
  Hello {{1}},
  
  How may I help you?
  
  Incorrect Format:
  Hello {{1}},
  
  
  How may I help you?
  
  
• Avoid using Emoticons in Quick Reply Buttons.
  
  
• Phone Number as Call to Action: The Phone Number must be written along with the country code without the plus (+) sign. If the number is submitted without the country code, it violates the format and gets rejected by WhatsApp.
