How to send payment links using SETU APIs?

When you want to send payment links to the users between a conversation on a bot, you can use SETU APIs, but the payment link is sent only on WhatsApp as a notification template, and not as a part of Bot Response.

The Fetch Bill and Send API is used to fetch a bill from Setu Collect Integration and send it across to the users.

API endpoint - https://prod.setu.co/v1/message/bill/fetch

Create an OAuth token to use the APIs. Read here to know more about generating tokens.

The following is the request format to use the API -

{
  "bill": {
    "customerIdentifiers": [
      {
        "attributeName": "string",
        "attributeValue": "string"
      }
    ]
  },
  "channels": [
    {
      "channel": "whatsapp",
      "template": {
        "name": "Alice",
        "biller": "Apna Finance"
      },
      "campaignID": "xxxx", # This is the Interakt capmaign id
      "destination": "91xxxxxxxxxx" # This number includes the country code as well
    }
  ]
}
