Account Holder

An Account holder is a real / legal Fusion customer. Drawing from the real world analogy, an account holder could be an actual person who holds an account at a bank or could be a legal entity like a corporate, merchant, etc. Account-holders can also be headless(anonymous),in which case we may not be able to ascertain the identity of the customer using identifiable documents.

An account corresponds to one single liability or asset ledger and represents monetary value in a given currency. In the above example the account ID is dc97c156-1fed-44c0-a7e4-5158f1fac042 Account is the actual entity that would hold money for the account holder. This is the actual account that would exist at, for example, HDFC bank in MG Road branch. Following are the set of APIs that would enable you to carry out various activities with regards to the accounts of an account holder.

  1. Get Account Holder Accounts List

    List of Accounts an Account holder holds can be fetched from Account holder ID

Above, when you would have tried to get accounts for the account holder, you would have realized that currently, it is empty. This is because you have to manually assign a bundle to the account holder and issue accounts using that bundle.Bundle is a concept that enables financial institutes to create and combine several products that could be sold together. Examples include an ICICI Salary account which gives you a Savings account bundled with a VISA Coral Debit card.It is also a manifestation of the application form and workflow (more on this in a later section). Importantly a product can only be availed by an end-customer through the construct of a bundle. After creating an account holder, you would need to assign a bundle to him/her.

  1. Issue Bundle

    By issue Bundle we are issuing one account and one payment product to an Account Holder.

  2. Issue Account Product

    Issue Account product helps in issuing multiple account products to the account holder.

As explained in the docs, when a bundle is issued, depending upon the type of product being bundled, the account holder is issued a payment product (usually) along with the account product. The payment product is manifested through a one-to-one mapping to the resource product which is nothing but an authenticable entity on behalf of an account holder. The resource product is internally mapped to ‘n’ number of payment instruments or form factors. One of these form factors is a card and another is a mobile.

  1. Get Resource

    Resource Details which in turn has the payment product details can be fetched using resource id. Payment products are internally mapped to a phone number and a card

    You can Simulate card transaction with the help of the card information you receive from Cards SDK.

  7. Replace Card

    In order to replace a card we need to fetch the card reference number of the existing card along with order id.

Bulk Card Orders

There are many practical real-world use cases and scenarios where you would want to bulk issue cards to your account holders.Fusion has a bulk card issuance API that allows you to solve for each of the above-mentioned pain points.
