GrabPay

Overview

Introduction

GrabPay is a payment method which allows you to process payments in Malaysian ringgits and in Philippine pesos by using e-wallets in Malaysia and in the Philippines. This method supports purchases (for Malaysia and the Philippines) and payouts (only for the Philippines).

This article provides information about working with the GrabPay method: general insights are presented in the Overview section, while information about the actions required to process payments and perform other actions is presented in the sections that follow.

Interaction diagram

Payment processing by using the GrabPay method involves the merchant's web service, one of ecommpay interfaces, the ecommpay payment platform, and technical facilities of the GrabPay service.



Operations support

Various platform interfaces can be used to process payments and perform operations using the GrabPay method. Purchases can be processed by using Payment Page, Gate, and Dashboard (using payment links). Payouts can be processed by using Gate and Dashboard. At the same time, regardless of the interfaces used, the following properties and limitations are applicable.

When working with the GrabPay the following properties and limitations are applicable.

Amounts, MYR Amounts, PHP Times ¹
minimum maximum minimum maximum basic threshold
Purchases 1.00 5,000.00 20.00 20,000 30 minutes 1 day
Payouts – – 1.00 50,000.00 * *

* For information about the basic and threshold times, contact your ecommpay account manager.

Note:
  1. The base and threshold times are defined as follows:
    • The base time is the average estimated time between the moment a payment is initiated in the payment platform to the moment the payment result is sent to the web service. The base time evaluation is made on the assumption of normal operation of all technical facilities and communication channels and typical customer behaviour (if any input from the customer is required). Use the base time to estimate when to react to the absence of payment result callbacks or when to check payment status (details).
    • The threshold time is the maximum possible time between the moment a payment is initiated in the payment platform to the moment the web service receives the callback with the payment result. A payment is automatically assigned the decline status if it wasn't processed within the threshold time. For individual customisation of the threshold time limit, contact ecommpay technical support.

Processing scenarios

To perform a purchase by using the GrabPay method, you need to redirect the customer to the GrabPay service, while to process a payout, you need to notify the customer via the web service.

The customer payment scenario via Payment Page looks like this.

Scenarios for performing operations via the main interfaces of the payment platform correspond to those presented in the diagrams. Similarly, when additional features (such as payment links) are used, scenarios for performing operations also correspond to the specifics of those features.

Purchases by using Payment Page

General information

To process a purchase through Payment Page by using the GrabPay method, the merchant's web service is required to send a request with all required parameters and signature to the ecommpay URL and receive a callback with the result. The full sequence and special aspects of purchase processing are provided below.

Information about the formats of requests and callbacks used for processing payments by using the GrabPay method via Payment Page is presented further in this section; general information about working with the Payment Page API is presented in Interaction concepts.

Request format

There are several things you need to consider when sending purchase requests by using the GrabPay method:

  1. The following parameters required for any payment must be specified:
    • project_id—project identifier obtained from ecommpay during integration
    • payment_id—payment identifier unique within the project
    • payment_currency—payment currency code in the ISO-4217 alpha-3 format
    • payment_amount—payment amount in the smallest currency unit
    • customer_id—customer identifier unique within the project
  2. The following parameters required for any payment must be specified: project_id, payment_id, payment_currency, payment_amount, customer_id.
  3. Additionally, it is recommended to specify the email, first and last names of the customer in the parameters customer_email (for both currencies), customer_first_name (for MYR), and customer_last_name (for MYR). If any of these parameters are missing, the payment form may display input fields for entering the missing values (details are available in Submission of additional payment information).
  4. If you need to have the payment form displayed with the GrabPay method selected, set the force_payment_method parameter to grabpay-wallet.
  5. Additionally, any other parameters available for working with Payment Page can be used (details).
  6. After all target parameters are specified, generate a signature (details).

Thus, a correct request for opening the payment form using the GrabPay method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer information and signature.

  17. The customer receives the payment result information from the web service.

Information about the formats of requests and callbacks used for processing payments by using the GrabPay method via Gate is presented further in this section. General information about working with the Gate API is presented in Interaction concepts.

Request format

There are several things you need to consider when sending purchase requests by using the GrabPay method:

  1. To initiate each purchase, send a separate POST request to the v2/payment/wallet/grabpay/sale endpoint. This endpoint belongs to the group /v2/payment/wallet/{payment_method}/sale.
  2. Each request must include the following objects and parameters:
    • Object general—general purchase information:
      • project_id—project identifier obtained from ecommpay during integration
      • payment_id—payment identifier unique within the project
      • signature—request signature generated after all required parameters are specified (details—in the Signature generation and verification) (details)
    • Object payment—payment information:
      • amount—payment amount in the smallest currency unit
      • currency—payment currency code in the ISO-4217 alpha-3 format
    • Object customer—customer information:
      • id—customer identifier unique within the project
      • ip_address—customer IP address relevant for the initiated payment
      • email—customer email address (only for requests where PHP is specified in the currency parameter)
    • Object return_url—contains the URLs to which customer is redirected while or after payment processing:
      • success—URL to return customer to the web service after a successful payment.
  3. Additionally, for payments in the MYR currency, it is recommended to specify the following objects and parameters:
    • Object customer—customer information:
      • email—email address of the customer
      • first_name—first name of the customer
      • last_name—last name of the customer

    If any of these parameters are missing, the payment platform may send the list of missing parameters in a callback requesting additional information submission (details are available in Submission of additional payment information).

  4. Additionally, any other parameters included in the specification can be used.

Thus, a correct purchase request by using the GrabPay method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer information, URL for redirection, and signature.

Formats of intermediate callbacks for customer redirection

Each payment made with the GrabPay method requires redirection of customers from the merchant's web service to the GrabPay service. To redirect a customer it is necessary to receive an intermediate callback from the payment platform and use the information included in the redirect_data object. The format of such callbacks is standard (details), and the following objects and parameters are included in the redirect_data object:

  • body—object with data to be sent in the request body
  • method—parameter specifying the HTTP method for sending the request (GET or POST)
  • url—parameter containing a link for redirection

"redirect_data": {
    "body": {},
    "method": "GET",
    "url": "https://test.ph/Pay.aspx?tokenid=3f511c2d&procid=BITC"
  }

Final callback format

The GrabPay method uses the standard format for callbacks to deliver purchase results. For more information, see Handling callbacks.

The following is the example of a callback with information about a 10.00 PHP purchase made in the 239 project.

  1. To initiate each payout send a separate POST request to the /v2/payment/wallet/grabpay/payout endpoint. This endpoint belongs to the group: /v2/payment/wallet/{payment_method}/payout.
  2. Each request must include the following objects and parameters:
    • Object general—general payout information:
      • project_id—project identifier obtained from ecommpay during integration
      • payment_id—payment identifier unique within the project
      • signature—request signature generated after all required parameters are specified (details—in the Signature generation and verification) details
    • Object payment—payment information:
      • amount—payout amount in the smallest currency unit
      • currency—payout currency code in the ISO-4217 alpha-3 format
    • Object customer—customer information:
      • id—customer identifier unique within the project
      • ip_address—customer IP address relevant for the initiated payout
    • Object account—customer account information:
      • number—account identifier, must consist of 11 digits starting with 09
      • customer_name—full customer name
  3. Additionally, any other parameters included in the specification can be used.

Thus, a correct payout request by using the GrabPay method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer and account information, as well as signature.

Callback format

The GrabPay method uses the standard format for callbacks to deliver payout results. For more information, see Handling callbacks.

The following is the example of a callback with information about a 10.00 PHP payout made in the 445 project.

Useful links

The following articles can be useful when implementing payouts via Gate:

Payouts by using Dashboard

When working with Dashboard, you can process single and mass payouts by using the GrabPay method.

  • To process a single payout, open the payout form, specify all required parameters (including the payment method), send a request and verify that the payout has been processed.

  • To process a mass payout, prepare and upload a file with information about all target payouts, send a batch request, and verify that the payouts have been processed.

    Use a CSV file structured according to the requirements presented in the Mass payments data section. The payout parameters must comply with the requirements (you do not have to generate a signature because it is specified by Dashboard).

More information about processing payouts by using Dashboard is presented in a separate section.

Analysis of payments results

To analyse information about payments made with the GrabPay method and other methods, you can use:

  • Dashboard interface toolkit with various lists and analytic panels.
  • Reports in CSV file format, available via the Reports section (one-time and periodically).
  • Data in JSON format, sent by program requests to a specified URL available by using the Data API interface.

If you have any questions, refer to the documentation (Dashboard and Using Data API) and ecommpay technical support.
