Additional Notes

Spreedly’s integration with the Vantiv eCommerce gateway uses the 9.14 version of their API.

Please note Vantiv eCommerce (formerly Litle) gateway flags “duplicate transactions” based on order_id. To avoid having legitimate transactions unfulfilled at the gateway, please ensure order_id is unique for supported transactions.

Merchant ID Only Auth Mode

Spreedly maintains “Partner-Presenter” credentials with Vantiv eCommerce (formerly Litle), certified for the current version of their API we are integrated with, which is version 9.14.

Note that Spreedly has two sets of these credentials - one for Production and one for the Prelive environment. The correct set is used depending on which environment is selected. Both are certified for API version 9.14.

If you wish to utilize these credentials instead of your own set of user and password, you must contact Vantiv and request that your Merchant ID be connected to Spreedly’s Partner Presenter credentials for each of Vantiv’s environments (Production and Prelive) that you wish to be able to transact against. If you are a merchant aggregator handling multiple Vantiv MIDs, each will need to be connected in this way.

Then, when creating a gateway, set mode to merchant_id_only, and provide only merchant_id.

The following example creates a Production gateway in merchant_id_only mode:


curl https://core.spreedly.com/v1/gateways.xml \
  -u 'C7cRfNJGODKh4Iu5Ox3PToKjniY:4UIuWybmdythfNGPqAqyQnYha6s451ri0fYAo4p3drZUi7q2Jf4b7HKg8etDtoKJ' \

Vantiv Environments and the URL Override Setting

The Vantiv eCommerce API has three environments:

  • Sandbox: A very basic, stateless testing environment
  • Prelive: A testing environment used for certification which will behave as expected by Vantiv’s test cases
  • Production: The live environment

Testing against Vantiv’s Prelive environment requires passing the url_override setting as prelive when creating a Spreedly gateway. Testing in their Sandbox requires passing only the sandbox setting to true. Note that if url_override is provided, the sandbox flag is ignored. Sending neither of these flags will create a Production gateway.

It is recommended that you create separate gateways for each environment you wish to transact in, rather than changing these values via an update gateway call against an existing gateway.

For clarity, this table lays out the Vantiv Environments and actual URL endpoints hit for certain gateway setting combinations:

Vantiv Environment Vantiv Endpoint URL sandbox setting url_override setting
Sandbox https://www.testvantivcnp.com/sandbox/ true Empty or Not Present
Prelive https://payments.vantivprelive.com/vap/ Any (Not Evaluated) prelive
Production https://payments.vantivcnp.com/vap/ false, Empty, or Not Present Empty or Not Present

The gateway created with the example call below will hit the Prelive environment in merchant_id_only mode (utilizing Spreedly’s Partner-Presenter Credentials):

curl https://core.spreedly.com/v1/gateways.xml \
  -u 'C7cRfNJGODKh4Iu5Ox3PToKjniY:4UIuWybmdythfNGPqAqyQnYha6s451ri0fYAo4p3drZUi7q2Jf4b7HKg8etDtoKJ' \
  -H 'Content-Type: application/xml' \
  -d '<gateway>
        <gateway_type>litle</gateway_type>
        <url_override>prelive</url_override>
        <mode>merchant_id_only</mode>
        <merchant_id>merchant_id</merchant_id>
      </gateway>'

Stored credentials regulations

For Litle there are two options for sending stored credential fields. You can either use Spreedly’s native support which is less hands on, or use gateway specific fields. Using gateway specific fields will give you more fine grain control over what is sent, however you will need to store additional data from the gateway that is returned in a gateway specific response field.

The three gateway specific fields are stored_credential_initiator, stored_credential_transaction_id, and stored_credential_processing_type. Note that the stored_credential_transaction_id is a Gateway Specific Response Field returned from the first use of a stored payment method. Additionally, it is different from a transaction’s gateway_transaction_id and you should track and provide with any subsequent transactions using that retained card.

Gateway specific fields

When interacting with a Vantiv eCommerce (formerly Litle) gateway to run transactions, there are some gateway specific fields you can specify.

Dynamic descriptors, descriptor_name and descriptor_phone, can be used by the merchant to define what will appear on the customer’s credit card statement for the purchase.

You can use report_group to separate your transactions into different categories.

order_source, customer_id, debt_repayment, campaign, affiliate, and merchant_grouping_id may also be sent.

3DSecure data can be passed using cavv and xid fields. Please note that in order for 3DSecure transactions to succeed with Vantiv, you must also send the order_source field with a value of either 3dsAuthenticated or 3dsAttempted.

Vantiv eCommerce may require an expiration date when transacting against debit cards vaulted on their platform. A transaction executed with the send_expiration_date_with_token field set to any value will send the expiration date for the corresponding card if the payment method used is a third party token.

fraud_filter_override may be sent with a boolean value. A setting of true will override (disable) all fraud filters for the submitted transaction.

You can pass these gateway specific fields like so:


curl https://core.spreedly.com/v1/gateways/LlkjmEk0xNkcWrNixXa1fvNoTP4/purchase.xml \
  -u 'C7cRfNJGODKh4Iu5Ox3PToKjniY:4UIuWybmdythfNGPqAqyQnYha6s451ri0fYAo4p3drZUi7q2Jf4b7HKg8etDtoKJ' \

Gateway specific response fields

A response from Vantiv eCommerce (formerly Litle) gateway may contain an network_transaction_id, authentication_result, post_date, litle_token, card_type, avs_response_code, or card_validation_code.

Note that the avs_response_code and card_validation_code returned uses Vantiv’s own codes, before translation into Spreedly’s standardized AVS and CVV response codes, which are also present in the base response.

You can find this information in gateway_specific_response_fields. For example, a transaction could have:

<transaction>
  <token>Y1QTi7ICTiV4EpYqCkCksUWQeJr</token>
  <transaction_type>Purchase</transaction_type>
  <gateway_specific_response_fields>
     <litle>
       <network_transaction_id>160280498621098</network_transaction_id>
       <authentication_result>1</authentication_result>
       <post_date>2018-02-19</post_date>
       <litle_token>1234567890</litle_token>
       <card_type>Credit</card_type>
       <avs_response_code>00</avs_response_code>
       <card_validation_code>M</card_validation_code>
     </litle>
  </gateway_specific_response_fields>
</transaction>
