Recurring payments

Recurring payments via Hyperswitch can be setup by passing some additional flags, as highligted below. The recurring payments are not tied to a specific amount or cycle and the merchant can charge the end-user as per their own business requirements.

Setting up a recurring card payment (CIT)

When setting up subscription there are two distinct implementation flows. The correct flow depends on whether you intend to charge the customer immediately or simply validate their details for later use.

1. The Setup with Charge Flow

Use Case: Use this when you need to collect a payment immediately (e.g., the first month of a subscription or a setup fee) while simultaneously saving the card details for future automatic charges.

Configuration Parameters :

• setup_future_usage: "off_session"

• amount > 0

2. The Zero Dollar Authorization Flow

Use Case: Use this for free trials, pay-later models, or delayed billing. This flow validates the payment method details without charging the customer's card.

Configuration Parameters :

• Pass below parameters while calling payments API for Zero Dollar Auth

• setup_future_usage: "off_session"

• amount: 0

• payment_type: "setup_mandate"

Once the CIT is successful, Hyperswitch returns a payment_method_id . This payment_method_id can be used by the merchant for all subsequent MIT recurring payments. Hyperswitch also returns the network_transction_id (NTID) in its response to allow PICI compliant merchants to direct pass card + NTID for processing MIT recurring payments

The payment_method_id serves as a unique identifier mapped to a specific combination of a Customer ID and a unique Payment Instrument (e.g., a specific credit card, digital wallet, or bank account).

• Logic: A single customer can have multiple payment methods, each assigned a distinct ID. However, the same payment instrument used by the same customer will always resolve to the same payment_method_id.

• Scope: This uniqueness applies across all payment types, including cards, wallets, and bank details.

Customer ID	Payment Instrument	Payment Method ID
123	Visa ending in 4242	PM1
123	Mastercard ending in 1111	PM2
456	Visa ending in 4242	PM3
123	PayPal Account ([email protected])	PM4

Internally the payment_method_id is mapped to a bunch of credentials - PSP token, Raw card + NTID, Network token + NTID depending on functionalities enabled for the merchant

The customer's consent is also necessary to store the card in the /payments/:id:/confirm request

"customer_acceptance": {
        "acceptance_type": "online",
        "accepted_at": "1963-05-03T04:07:52.723Z",
        "online": {
            "ip_address": "in sit",
            "user_agent": "amet irure esse"
        }
    }

If you are using the Hyperswitch SDK, the customer_acceptance is sent in the /payments/:id:/confirm request on the basis of customer clicking the save card radio button

Note: Ensure to enable this functionality using the displaySavedPaymentMethodsCheckbox property during SDK integration

Supported MIT Flows

Hyperswitch supports decoupled transaction flows, allowing Merchant-Initiated Transactions (MITs) to be processed independently of the original Customer-Initiated Transaction (CIT), even when the CIT was completed outside the Hyperswitch platform.

MITs are initiated by invoking the /payments API with off_session: true and providing the available reference data in the recurring_details object. Depending on the artifacts available in your system, one of the following approaches can be used:

Payment_method_id : Submit the Hyperswitch generated payment_method_id to process the MIT transaction. Depending on the merchant configurations the MIT will be processed with the same PSP or with a different PSP.

Processor Payment Token : Submit a processor-issued token that represents the previously authorized payment instrument.

Network Transaction ID with Card Data : Provide the original network transaction identifier along with the associated primary card data required for authorization.

⚠️ PSP Configuration Required

This feature is not enabled by default and must be explicitly enabled by PSP.

You may receive errors such as Received unknown parameter: payment_method_options[card][mit_exemption], follow the steps below to request activation.

Email the PSP Support requesting:

• Access to the mit_exemption parameter for MIT (Merchant Initiated Transaction) payments

• Ability to pass network_transaction_id in the parameter: payment_method_options[card][mit_exemption][network_transaction_id]

• Explain your use case: enabling cross-processor MIT payments using network transaction IDs from card schemes

Network Transaction ID with Network Token : Submit the network transaction identifier in combination with the corresponding network tokenized card credentials.

Limited Card Data : Use a reduced card data set captured at the time of subscription creation to authorize subsequent MITs.

PG agnostic MITs

The CIT used to set up recurring payments via MIT uses the PG token. This introduces a connector stickiness since the recurring payments can only go through the connector which issued the token.

To mitigate this we would be storing the Network Transaction ID which will be a chaining identifier for the CIT in which the payment method was saved for off-session payments.

In the following MIT payments basis the enablement of the feature and the availability of Network Transaction ID Hyperswitch will route your payments to the eligible set of connectors. (This will also be used for retries)

Enabling PG agnostic MITs

To start routing MIT payments across all supported connectors in addition to the connector through which the recurring payment was set up, use the below API to enable it for a business profile

curl --location 'http://sandbox.hyperswitch.io/account/:merchant_id/business_profile/:profile_id/toggle_connector_agnostic_mit' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: api_key' \
--data '{
    "enabled": true
}'

All the payment methods saved with setup_future_usage : off_session after enabling this feature would now be eligible to be routed across the list of supported connectors during the subsequent MIT payments

Routing example - CITs are routed through PSP-1 and all MITs through PSP-2

The Hyperswitch dashboard provides UI to configure routing rules for PG Agnostic Recurring Payments. You can choose the profile for which you wish to configure the rule in the Smart Routing Configuration.

Then, you can configure the rule as shown below using the metadata field in the Rule-Based Configuration.

This rule would be used in conjunction with the other active routing rules that you have configured.

Once the rule is configured, you would need to send the following metadata as per the payment request:

-> Metadata to be sent in CITs

"metadata": {
    "is_cit": "true"
}

-> Metadata to be sent in MITs

"metadata": {
    "is_mit": "true"
}

According to the above configured rule all the CITs for the specific business profile should be routed through Stripe and MITs through Adyen.
