1.2. Card Not Present API (Mobile Device)

1.2.1. General information

Participants

Consumer would like to make payments or money transfers with Merchant’s mobile app on his mobile device.
Merchant’s app allows Consumer to process the transactions via secure Mobile Device API (DAPI) integration to Industra.
Merchant’s server or Merchant’s proxy is used to store and transfer data about user’s authentication credentials and card mapping information.
Industra processes the transactions with EFT (Electronic Funds Transfer participants - Acquirer banks, Issuer banks and Global Card Systems).
3DS flow between banks, Global card systems (Visa, MasterCard, etc) and Industra is simplified on the schemes below, please see 3-D Secure (3DS) for details.

Quick integration guide

  1. Optional consumer authentication is used to create {accessToken}, which is required in integration of any transaction type.
  2. Transaction types supported in DAPI at the moment: Card verification, Sale, Money transfer.
  3. Signature computation contains information and debugging tool for request-response signatures in DAPI.
  4. Merchant Callbacks implementation is the most appropriate way to get transaction’s status for Merchant’s server.
  5. Depending on the integration, Alternative cardholder authentication (non3D) can be used for cards without support of 3-D Secure technology. For details, please contact your Support manager.
  6. Example code and SDK contains integration solutions for Merchant’s server, Android and iOS platforms.

Optional consumer authentication

To perform authentication of Consumer in Merchant’s app, Merchant can use any method which fits best to his needs.
As a result, Merchant’s server generates {accessToken} and provides it to Merchant’s app. This parameter will be used to start and continue session for all transaction types supported by DAPI.

title Mobile Device - Optional consumer authentication skinparam ParticipantPadding 70 participant client as "Consumer" participant mobile as "Mobile App" participant merchant as "Merchant's Server" mobile <-> client : Authentication merchant <- mobile : Request access token note left token credentials end note mobile <-- merchant note right accessToken end note

This step is not displayed on the integration schemes below.

Alternative cardholder authentication (non3D)

DAPI supports alternative methods for cardholder authentication if 3DS enrollment request to EFT returns negative response.
Those methods can be used for all types of transactions supported by DAPI, depending on the integration.
One of such methods is random sum check. In this method, Industra addresses directly to Acquirer Bank to hold a random small amount on cardholder’s account, then sends redirect url to Merchant’s app.
Merchant’s app then opens the browser for Consumer to enter the amount being held in Industra special form.
If the amount is correct, Industra continues to process the initial transaction. The small amount hold is cancelled automatically by Acquirer Bank.

1.2.2. Card verification

DAPI allows Consumer to make transfer and sale transactions easier with a single verification process. During the process, the card is being validated by Industra, authenticated with 3DS/non-3DS by EFT and then mapped to reference on Merchant’s server. It allows Consumer to avoid entering card data for each transfer or sale transaction. Integration is based on HTTP POST requests/responses with JSON data. You may see the general flow process below:

Initiate verification

To initiate card verification, Merchant’s app sends {accessToken} with other device parameters to Merchant’s server. These parameters are used to start a session with unique random {nonce} and encrypted {signature}. In response Merchant’s server also provides information about {invoiceId} in merchant’s system and {endpointId} in Industra.

Verification card mapping notification

Card mapping notification is used to allow Consumer credentials (phone, email, billing address, twitter name, etc) for mapping to card data. Card mappings can be used later in transfer or sale transactions instead of card numbers and other cardholder information. Industra sends Verification card mapping notification request to Merchant’s server/proxy with created on its side card reference - {serverCardId}.
Merchant’s server maps this {serverCardId} to {clientCardId}, created on its side. This {clientCardId} can then be mapped in Merchant’s app or on Merchant’s server to any Consumer’s data from the initial Perform validation request. This allows Merchant’s app to process sale or transfer transactions by Consumer’s email, phone number, etc.
{uniqueReferenceCardId} remains the same if Consumer makes another verification with the same card number but different expiry date, for example. It can be used by Merchant for loyalty programs or fraud control.

Sale status

Sale status request is made by Merchant’s app to Industra to get the status of sale transaction.
It is recommended to send Sale status request for a period of 2-3 minutes with interval of 3-5 seconds between requests.

Sale card mapping notification

Card mapping notification is used to allow Consumer credentials (phone, email, billing address, twitter name, etc) for mapping to card data. Card mappings can be used later in transfer or sale transactions instead of card numbers and other cardholder information. Industra sends Sale card mapping notification request to Merchant’s server/proxy with created on its side card reference - {serverCardId}.
Merchant’s server maps this {serverCardId} to {clientCardId}, created on its side. This {clientCardId} can then be mapped in Merchant’s app or on Merchant’s server to any Consumer’s data from the initial Perform sale request. This allows Merchant’s app to process sale or transfer transactions by Consumer’s email, phone number, etc.
{uniqueReferenceCardId} remains the same if Consumer makes another transaction with the same card number but different expiry date, for example. It can be used by Merchant for loyalty programs or fraud control.
Merchant’s app makes new sale requests using {clientCardId} instead of source card data. Industra sends this {clientCardId} to Merchant’s server in “Check sale request” and gets mapped to it {serverCardId} in “Check sale response” from Merchant’s server, which is used to continue the processing of this transaction.
{serverCardId} of source or verified card can be used for new sale transactions and both as source or destination for new transfer transactions.

Sale card mapping notification request is sent by Industra through HTTPS POST to URL (provided by merchant)

https://proxy.merchantserver.com/sale/notification

Request body

In the request body, data is supplied with the following structure:

Repeat sale

After successful Card mapping procedure, new sale transactions with the same cardholder data can be done easier for Consumer.
Merchant’s app makes new sale requests using {clientCardId} instead of cardholder data. Industra sends this {clientCardId} to Merchant’s server in “Check sale request” and gets mapped to it {serverCardId} in “Check sale response” from Merchant’s server. This {serverCardId} is used to continue the processing of sale transaction.
Transaction flow remains the same: Initiate sale -> Perform sale -> Check sale.
If there is no need to change Consumer’s data (such as address, phone, etc.), “Perform sale request” for Repeat sale may be sent without any optional parameters. If Consumer’s data has to be changed, new source card reference must be created.
If {clientCardId} is used in “Perform sale request”, {serverCardId} must be included in “Check sale response” and signature.
If {clientCardId} was mapped to {serverCardId} in transaction with included {consumer.email} value, new “Perform sale request” and “Check sale response” with this {clientCardId} must also contain the same {consumer.email} value.
You can see the card reference management on the scheme below:

title Mobile Device - Card references for Repeat sale participant mobile as "Mobile App" participant merchant as "Merchant's Server" participant pne as "Payneteasy" skinparam ParticipantPadding 80 ... Last part of previous transaction ... merchant <- pne: Card mapping notification request note right serverCardId end note merchant --> pne: Card mapping notification response merchant --> merchant: Create clientCardId for serverCardId group optional merchant -> mobile: Store reference in app or send it by request note right clientCardId end note end ...

For source of funds in “Repeat sale” use:
  1. {sourceOfFunds.reference.clientCardId}
  2. {sourceOfFunds.reference.securityCode}
Instead of:
  1. {sourceOfFunds.card.expiry.month}
  2. {sourceOfFunds.card.expiry.year}
  3. {sourceOfFunds.card.holder}
  4. {sourceOfFunds.card.holder.firstName}
  5. {sourceOfFunds.card.holder.lastName}
  6. {sourceOfFunds.card.number}
  7. {sourceOfFunds.card.securityCode}

1.2.4. Money transfer

Money transfer can be performed with cardholder data of sender and receiver of funds or with card reference, previously made with Card verification process or in previous transfer/sale transactions. You may see the general flow process for money transfer below.

title Mobile Device - 3-D Secure card funds transfer skinparam ParticipantPadding 70 participant client as "Consumer" participant mobile as "Mobile App" participant merchant as "Merchant's Server" participant pne as "Industra" participant bank as "EFT" client -> mobile: Start transfer transaction merchant <-> mobile: Initiate transfer mobile -> pne: Perform transfer pne -> pne: check signature mobile <-- pne: Status info note right session token end note pne <-> merchant : Check transfer pne <-> bank : Check 3DS enrollment loop until final status is sent mobile -> pne: Transfer status request note left session token end note mobile <-- pne note right state = PROCESSING end note end mobile <- pne: Open browser and redirect to EFT note right ACS url PA Request Term url Merchant data end note activate mobile mobile -> bank mobile <-- bank: Response with 3DS html form client <-- mobile client -> mobile: The cardholder provides auth data mobile -> bank mobile <-- bank: Redirect browser back to Industra note right PA Response Merchant data end note mobile --> pne: Transfer status update pne --> mobile: Close browser request destroy mobile pne <-> bank: 3DS auth result note left PA Response end note note right cavv eci status end note pne <-> bank: process transfer note right bankorder id end note merchant <-> pne: Transfer card mapping notification note right server card id end note mobile <-- pne: Transfer status response note left bankorder id state = APPROVED|DECLINED end note

Initiate transfer

To initiate funds transfer, Merchant’s app sends {accessToken} with transaction amount and other device parameters to Merchant’s server, which are used to start a session with unique random {nonce} and encrypted {signature}.
In response Merchant’s server also provides information about invoice in merchant’s system and endpoint in Industra.
The Merchant’s server may also respond with the transaction’s commission.

Transfer card mapping notification

Card mapping notification is used to allow Consumer credentials (phone, email, billing address, twitter name, etc) for mapping to card data. Card mappings can be used later in transfer or sale transactions instead of card numbers and other cardholder information. Industra sends Transfer card mapping notification request to Merchant’s server/proxy with created on its side card reference - {serverCardId}.
Merchant’s server maps this {serverCardId} to {clientCardId}, created on its side. This {clientCardId} can then be mapped in Merchant’s app or on Merchant’s server to any Consumer’s data from the initial Perform transfer request. This allows Merchant’s app to process sale or transfer transactions by Consumer’s email, phone number, etc.
{uniqueReferenceCardId} remains the same if Consumer makes another verification with the same card number but different expiry date, for example. It can be used by Merchant for loyalty programs or fraud control.
Merchant’s app makes new transfer requests using {clientCardId} instead of source or destination card data. Industra sends this {clientCardId} to Merchant’s server in “Check transfer request” and gets mapped to it {serverCardId} in “Check transfer response” from Merchant’s server, which is used to continue processing the transfer transaction.
{serverCardId} of source or verified card can be used both as source or destination for new transfer and sale transactions; {serverCardId} of destination card can be used only as destination for new transfers.

Transfer card mapping notification request is sent by Industra through HTTPS POST to URL (provided by merchant)

https://proxy.merchantserver.com/transfer/notification

Repeat transfer

After successful Card mapping procedure, new transfers with the same cardholder data can be done easier for Consumer.
Merchant’s app makes new transfer requests using {clientCardId} instead of source and/or destination cardholder data. Industra sends these {clientCardId} to Merchant’s server in “Check transfer request” and gets mapped to it {serverCardId} in “Check transfer response” from Merchant’s server. These {serverCardId} are used to continue the processing of transfer transaction.
Transaction flow remains the same: Initiate transfer -> Perform transfer -> Check transfer.
If there is no need to change Consumer’s data (such as address, phone, etc.), “Perform transfer request” for Repeat transfer may be sent without any optional parameters and with card references for sender and receiver instead of cardholder data. If Consumer’s data has to be changed, new source card reference must be created.
If source and/or destination {clientCardId} are used in “Perform transfer request”, source and/or destination {serverCardId} must be included in “Transfer check response” and signature.
If source {clientCardId} was mapped to {serverCardId} in transaction with included {consumer.email} value, new “Perform transfer request” and “Check signature response” with this {clientCardId} must also contain the same {consumer.email} value.
You can see the card reference management on the scheme below:

title Mobile Device - Card references for Repeat transfer participant mobile as "Mobile App" participant merchant as "Merchant's Server" participant pne as "Payneteasy" skinparam ParticipantPadding 80 ... Last part of card verification or transfer ... merchant <- pne: Card mapping notification request note right serverCardId end note merchant --> pne: Card mapping notification response merchant --> merchant: Create clientCardId for serverCardId group optional merchant -> mobile: Store reference in app or send it by request note right clientCardId end note end ... New transfer ... mobile <-> merchant: Initiate transfer mobile -> pne: Perform transfer request note left clientCardId end note mobile <-- pne: Perform transfer response merchant <- pne: Check transfer request note right clientCardId end note merchant --> pne: Check transfer response note left serverCardId end note pne -> pne: Process transfer ...

For source of funds in “Repeat transfer” use:
  1. {sourceOfFunds.reference.clientCardId}
  2. {sourceOfFunds.reference.securityCode}
Instead of:
  1. {sourceOfFunds.card.expiry.month}
  2. {sourceOfFunds.card.expiry.year}
  3. {sourceOfFunds.card.holder}
  4. {sourceOfFunds.card.holder.firstName}
  5. {sourceOfFunds.card.holder.lastName}
  6. {sourceOfFunds.card.number}
  7. {sourceOfFunds.card.securityCode}
For destination of funds in “Repeat transfer” use {destinationOfFunds.reference.clientCardId} instead of {destinationOfFunds.card.number}.

Consumer defined transfer rates

Consumer defined transfer rates is an optional feature which allows the sender to choose the most suitable commission amount for his transfer transaction between several available payment gateways.
The possibility of such feature depends on the integration. Please ask your support manager for details.
When such feature is enabled, the transaction flow extends:
  1. If Check transfer has been successful, Industra pauses the processing, includes the list of possible commissions to next Transfer status response and awaits for confirmation from the Consumer.
  2. Consumer selects the most suitable commission from the list in the Merchant’s app.
  3. Merchant’s app sends the selected gate in Complete transfer request to Industra.
  4. Industra continues to process the transaction on the selected gate.

This flow is also represented on the scheme below:

title Consumer defined transfer rates participant client as "Consumer" participant mobile as "Mobile App" participant pne as "Industra" participant bank as "EFT" ... Transfer has been checked successfully ... pne -> pne : Pause the transaction loop until Complete transfer is sent mobile -> pne: Transfer status request note left session token end note mobile <-- pne: Transfer status response note right state=TRANSFER_FEE_REQUEST transferFeeList [...] end note end mobile -> client: Ask to select the commission mobile <-- client: Commission selected mobile -> pne: Complete transfer request note left assignedId end note mobile <-- pne: Complete transfer response pne -> bank: Process transfer \non the selected gate ...

Transfer status response includes the state parameter with TRANSFER_FEE_REQUEST value and the transferFeeList object with a list of commissions for possible processing gates.
Each processing gate is represented by it’s own aliased name in assignedId parameter.
TRANSFER_FEE_REQUEST value in state parameter exists only in “Consumer defined transfer rates” flow.
The mentioned parameters may not be presented in first Transfer status response, so Merchant’s app should continue polling the transaction status.
When the transaction reaches TRANSFER_FEE_REQUEST state, the processing will remain paused until Complete transfer request is sent.

The following structure extends the default Transfer status response body (e.g. 2 processing gates):

{
  "state": "TRANSFER_FEE_REQUEST",
  "transferFeeList": [
    {
      "assignedId": "string",
      "commissionCentis": "integer",
      "currency": "string"
    },
    {
      "assignedId": "string",
      "commissionCentis": "integer",
      "currency": "string"
    }
  ]
}
Property name Value Description
transferFeeList object  
transferFeeList.assignedId string Aliased payment gateway name
transferFeeList.commissionCentis integer Amount of commission to be held in centis, 1.00 EUR = 100 centis
transferFeeList.currency string Upper case letters (ISO 4217 alpha code)
state string In addition to the values from Transfer status, TRANSFER_FEE_REQUEST value only exists in this flow

Complete transfer request is sent by Merchant’s app through HTTPS POST to URL

https://ecom.industra.finance/paynet/dapi/v1/transfer/{endpointId}/{invoiceId}/{assignedId}

In the request body, supply data with the following structure:

{

Signature computation

The signature is being used to ensure that it is Merchant (and not a fraudster) who sends the information to Industra.
Signatures in DAPI are computed using HMAC_SHA1 algorithm. Key is derived in the following way:
  1. Take merchantControlKey
  2. Remove dashes from it
  3. Unhex the result to binary

You can get the correct signature values for all types of transactions supported by DAPI in the debugging tool below:

AccessToken Use your existing accessToken or make it for new transaction
Serial number
Endpoint ID
Session nonce Use your existing nonce or make it for new transaction
Merchant's invoice Use your existing invoiceId or make it for new transaction
Transaction currency ISO 4217 alpha three-letter code
Merchant control key

String to sign
Signature
