Motivation and Context

How did you test it?

Tested it locally

• Create a merchant account with the field

  "routing_algorithm": {
        "type": "priority",
        "data": [],
        "timestamp":"{{$timestamp}}"
    },
    

it will get stored with a default algorithm :

• Similarly, for business_profile_create and update as well as merchant_account_update
