Complete a Payment [v3]​

This API helps you complete a payment that you have already initiated. You need to call this API typically to submit an otp or a token to complete the payment. Currently this API is used only for certain Pay Later providers where you want to provide a native otp experience.

Request Body required
    transaction_id string required

    The transaction_id for which the payment needs to be completed, this should be the same as returned in the response of initiate payment

    payment_flow string required

    Possible values: [otp, auto_debit]

    There are two ways to complete the payment flow, either by the customer submitting an otp or without any consumer action when an auto_debit token exists for the user. The flow to be sent here will come in the response of v3/initiate-payment API. If the flow is otp, you will need to provide an OTP entry screen for your customer.

    otp string nullable

    This is the OTP that is sent to the customer to authenticate the transaction. You need to pass it when the payment_flow is otp

    encrypted_otp string nullable

    You can always encrypt the OTP on your client and send us the encrypted OTP string in this key.

    Steps for encryption

    1. Get the Nimbbl Public key for encryption. To get the Nimbbl public key reach out to us at help@nimbbl.biz.
    2. Format the Card details in the format : {"otp":"123233"}
    3. Encrypt the above card details using the RSA encryption.
