Interaction diagram

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



Operations support

Various platform interfaces can be used to process payments and perform operations using the GCash method. Purchases can be processed by using Payment Page, Gate and Dashboard (using payment links), payouts—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 GCash the following properties and limitations are applicable.

Amounts, PHP Times ¹
minimum maximum basic threshold
Purchases 1.00 10,000.00 30 minutes 1 day
Payouts 10.00 100,000.00 24 hours 48 hours
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 GCash method, you need to redirect customer to the GCash service, while to initiate 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 GCash 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 GCash 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 GCash 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. It is recommended to specify the e-mail address of the customer in the customer_email additional parameters. If the request is missing the parameter, on Payment Page the additional field is displayed to the customer to input missing data. If the parameter is specified in the request, n Payment Page the additional pre-filled field is displayed to the customer. The field contains the value specified in the request, the customer can verify or change the email.
  4. If you need to have the payment form displayed with the GCash method selected, set the force_payment_method parameter to gcash-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 GCash 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 GCash 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 GCash method:

  1. To initiate each purchase, send a separate POST request to the v2/payment/wallet/gcash/sale endpoint, which 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
      • email—customer email address
      • ip_address—customer IP address relevant for the initiated payment
    • 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, any other parameters included in the specification can be used.

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

    },
    "return_url": {

Formats of intermediate callbacks for customer redirection

Each payment made with the GCash method requires redirection of customers from the merchant's web service to the GCash 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
Figure 16. redirect_data example
  "redirect_data": {
    "body": {},
    "method": "GET",
    "url": "https://www.example.com/pay"
  }

Final callback format

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

The following is the example of a callback with information about a 10.00 PHP purchase made in the 239 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. The currency of payout can only be PHP.
  4. Additionally, any other parameters included in the specification can be used.

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

Callback format

In the GCash method, the callbacks that deliver payout results use the standard format described in 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 GCash 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 GCash 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.
