Payment Methods

In the intricate realm of online transactions, a versatile payment experience is essential. The Payment Methods API streamlines this process, allowing for effortless automation. by simply integrating with specified operation, customer_id, currencies, payment gateway names and desired payment plugins, merchant can harness the full power of Ottu's payment automation, all while keeping his existing environment intact. no extra effort, just seamless integration.

Ensure the relevant plugin (E-Commerce or Payment Request) is activated in the Admin Panel under the Plugin Config section. For detailed activation steps, refer to the Plugin Activation Guide.

Activate the payment gateway (pg_codes) you intend to use. Ensure all desired pg_codes are set to ‘active’ status in your configuration.

The type filter determines the mode of your environment:

  • Development Mode: Configure the type to sandbox mode for conducting tests with sandbox transactions instead of live transactions.

  • Production Mode: Set the type to production for handling real transactions in a live environment.

Ensure you’re in the correct mode before initiating payments.

Supported Methods

For detailed information on authentication procedures, please refer to the Authentication documentation.

Ensuring the right level of access is crucial for maintaining the security and integrity of your payment processes. The Payment Methods API provides two authentication methods, each with its own set of permissions:

Private API Key

  • Privileges: This method grants super admin privileges to the caller. It provides unrestricted access to all available payment methods and associated functionalities.

  • Usage: Given its broad access, it’s essential to handle API keys with utmost care. Ensure they are securely stored and only shared with trusted individuals or systems.

BasicAuth

  • Privileges: BasicAuth is user-centric, meaning it’s tied to a specific user profile. Access to payment methods can be restricted based on the user’s assigned permissions.

  • Setting Permissions: To grant a user access to a specific payment method, assign the permission: "Can use pg_code". Here, the pg_code represents the unique code of the payment gateway or merchant ID (MID). For instance, if you want to grant a user access to a payment gateway with the code ‘credit-card’, you would assign them the permission “Can use Credit Card”.

  • Usage: Since BasicAuth is user-specific, it’s suitable for scenarios where you want to provide selective access to different payment methods based on user roles or responsibilities.

The Payment Methods API is designed to streamline and automate the end-to-end integration with Ottu, ensuring that your payment processes remain up-to-date and efficient without the need for constant code modifications.

  1. Automation and Flexibility: This API serves as a foundation for other Ottu APIs, providing the necessary data to facilitate seamless transactions. By using this API, you can ensure that your integration remains current, even when there are changes in the payment gateway configurations.

  2. Caching for Efficiency: Given that the data from the Payment Methods API doesn’t change frequently, it’s recommended to cache the response for 24 hours. This approach enhances performance and reduces unnecessary API calls. However, ensure you have a mechanism to clear the cache when immediate updates are required.

  3. Tailored Customer Experience: With various filters available, you can customize the payment methods presented to the customer. For instance, if you’re setting up a customer for recurring payments, you can filter out payment methods that don’t support tokenization using the tokenizable=true filter.

  4. Versatility: The Payment Methods API isn’t just a prerequisite for the Checkout API. It’s also essential for other APIs, such as the User Cards API.

  • Currency-Specific Payments: If you want to allow payments only in a specific currency, like USD, use the filter currencies=["USD"]. This will return only the payment methods that support USD.

  • Recurring Payments: When setting up a customer for recurring payments, use the tokenizable=true filter. This ensures that the customer can set up a recurring payment using methods that support tokenization.

  • Customized Payment Options: If you have a history of the payment methods a customer has used, you can tailor the options presented to them during checkout. Instead of showing numerous payment methods, display only those they’ve used in the past.

  • Specific Payment Types: For purchases where only specific payment types, like Debit Cards, should be allowed, use filters like pg_names=["kpay"] to retrieve only the desired payment methods.

Example:

To retrieve payment methods that support USD and tokenization for e-commerce purchases:

POST: https://beta.ottu.net/b/pbl/v2/payment-methods/
{
    "plugin": "e-commerce",
    "operation": "purchase",
    "tokenizable": "true",
    "currencies": ["USD"]
}

This request will return the "pg_codes": ["kpay"], which can then be used in subsequent API calls.

For a detailed breakdown of the API response, refer to the Open API block below.

The Payment Methods API provides a wealth of information about each available payment method. It’s not just about determining which payment methods are available; it’s about understanding the capabilities and features of each method in-depth.

Key insights you can glean from the API response include

  • Capabilities: Understand what each payment method is capable of. This includes operations like refunds, voids, and captures.

  • Wallet Integrations: Determine which payment methods support popular digital wallets like Apple Pay and Google Pay.

  • Supported Currencies: Identify the currencies each payment method can handle. This is crucial for businesses operating in multi-currency environments.

  • And More: The API provides a plethora of other details that can be instrumental in tailoring the payment experience for your customers.

With such granular control and detailed insights at your fingertips, you can truly customize and optimize the payment process to align with your specific business needs and offer an unparalleled payment experience to your customers.

    When planning for subsequent charges, the merchant uses the Payment Methods API to retrieve tokenization supported pg_codes.

  2. Passing Tokenization pg_codes to User Cards API

    The retrieved tokenization pg_codes are then passed to the User Cards API. The User Cards API filters and returns only those saved cards that are enabled for tokenization by the customers.

  3. Subsequent Transactions

    For subsequent transactions, the system only charges the customer's cards that are both saved and have tokenization enabled.

Customers are assured that only their approved and tokenization enabled cards will be charged, ensuring transparency and trust.

Given the infrequent changes in values — primarily when new MIDs are issued — it’s prudent to cache the API call response. This minimizes unnecessary and redundant calls to the API, especially considering the rare changes.

Recommendations

  • Cache the API call response for an extended period, ranging from 24 hours to 1 week. This ensures that you’re not querying the API for every payment, which is inefficient since the data remains largely static.

Always cache responses based on the specific filters you apply during API calls. If you’re employing the API with diverse filters based on various scenarios, it’s crucial to cache each response separately.

Why is this important? If you cache all responses under a single key, regardless of the filters used, you risk retrieving incorrect or irrelevant data. This can lead to inaccurate payment processing or even transaction failures. Caching each filter’s response under a unique key ensures data integrity and relevance.

Implement a mechanism to clear the cache on demand. In instances where a change for MID is enacted in the Ottu admin panel, this mechanism should be triggered to force update the cache with the latest data.

Benefits

  • Guarantees that your system always has the most up-to-date information.

  • Prevents potential transaction issues stemming from outdated MIDs.

By adhering to these best practices, you’ll ensure efficient API usage, maintain data accuracy, and optimize payment processing.
