Send e-Receipts

Following each purchase, either in-store or online, your customers can easily opt-in to receive their receipt in digital format over WhatsApp.

By implementing this use case, end users can easily store their receipts for a refund claim. And at the same time, their receipt is sent and stored in a digital form reducing the carbon footprint.

Have in mind that before you start communicating with your customers over WhatsApp, you must receive and store their opt-ins.

This use case will show you how to send a WhatsApp media message template containing a document file over Infobip API.

Process Workflow

IMPLEMENTATION STEPS

Before you can start sending message templates, your template needs to be approved by WhatsApp. Once you create the e-receipt template and it has been approved by WhatsApp, you can reuse it and personalize it for other customers.

Use additional placeholders to personalize your message.

You define the media in the header (image or document) and insert text information in the template body.

To send this notification to a specific customer using the WhatsApp API, follow the steps described below.

1. Log in to the Infobip API Developer Hub.

2. Copy your base URL.

(e.g., your personal base URL is: https://{{BASE_URL}}.api.infobip.com/)

Steps over API

1. Choose the POST method

2. Replace endpoint with https://{{BASE_URL}}.api.infobip.com/omni/1/advanced

3. Add the Authorization header.

For example, Basic: Base64 encoded username and password (

4. Copy the scenarioKey you previously created

5. Specify the destination phoneNumber you wish to send the notification to.

6. Replace the templateName, documentUrl, documentFilename, placeholders, and language fields with registered ones (refer to the table above).  

The header fields contain the document URL and document file name, while the placeholders in the template body are contained in  placeholders field

{
   "scenarioKey":"CC9F01A5DC7BEE2C2B829D203482A654",
   "destinations":[
      {
         "to":{
            "phoneNumber":"41793026727"
         }
      }
   ],
   "whatsApp":{
      "templateName":"e_receipt",
           "mediaTemplateData": {
		"header": {
		  "documentUrl": "https://documenthost.com/purchase_no10859302.pdf",
		"documentFilename": "Purchase Number 10859302"
},
		"body": {
			"placeholders": []
		}
	},
      "language":"en"
   }
}

If the media type in the registered template is an image instead of document, the mediaTemplateData should contain information on image URL and real data for the placeholders.
