Param for Merchants: Products, Features, Integration, and Practical Considerations

Choosing a payment partner affects your conversion rates, cash flow, and operational overhead. Param provides a set of merchant solutions covering online, mobile, and marketplace payments. This overview explains how Param works, what you can deploy quickly, and where it fits best. Param offers Virtual POS for e-commerce and remote collection, along with developer tooling, plugins for common platforms, and next-day settlement options.

What Is Param?

Param is a payment solutions provider with a Virtual POS platform designed for card-not-present payments. It focuses on a single-contract model across many Turkish acquiring banks, installment support, and accelerated settlement. The stack includes APIs, hosted payment page options, plugins for popular e-commerce systems, and capabilities for card vaulting, pre-authorization, and sub-merchant marketplace payouts.

Core Products and Payment Flows

Virtual POS for Online Payments

Param’s Virtual POS allows merchants to accept card payments online using either 3D Secure or non-3D flows. Merchants can initiate transactions, redirect to bank pages for 3D verification, or complete a non-secure flow when permitted by card program and MCC rules. The platform supports single-shot and installment payments, with installment logic and commissions configurable per bank and tenure.

Key points:

• 3D Secure and non-3D transaction flows

• Installment support with per-bank, per-tenure rates

• Next-day settlement positioning for approved businesses

• One-contract coverage for many banks

Hosted Payment Page and Payment Links

If you prefer not to host payment fields, Param offers a shared payment page and iFrame flow. You can generate a link that directs customers to a hosted checkout, reducing your PCI scope and speeding up go-live for simple use cases such as pay-by-link collections or one-off invoices.

Card Vaulting and Recurring Charges

Param provides tokenized storage of card details via its Card Storage APIs. You can store cards, retrieve a list of stored cards, and charge a stored token either with 3D Secure where required or in non-3D mode when allowed. This is suitable for subscriptions, pay-as-you-go services, and repeat customers.

Pre-Authorization and Capture

Param supports pre-authorization to place a hold on funds and capture later, along with cancel and refund operations. This is useful for reservations, rentals, and higher-risk order review flows.

Marketplace Capabilities

For platforms that onboard multiple sellers, Param’s Marketplace APIs allow sub-merchant registration, order detail allocation, split settlement to sub-merchant IBANs after commission deduction, and transaction queries. These tools support basic marketplace compliance and payout orchestration within Param’s environment.

Payment Methods, Banks, and Installments

Param’s model emphasizes broad card acceptance and installment programs commonly used in Turkey. According to Param’s materials, merchants can avoid separate technical integrations with many individual banks and instead sign one agreement while still offering installments across major card programs. Within the Virtual POS, installment coefficients and commissions can be configured per bank and for each installment month (for example, 2, 3, 6, 9, 12). Developers can query and manage these rates via dedicated API methods.

Param also documents support for local digital wallets such as BKM Express and Masterpass, as well as payment with points and foreign currency options. If your checkout targets domestic Turkish cards with installment expectations, these options can help align payment UX with local purchasing behavior.

Security, Compliance, and Risk Controls

Param’s documentation and merchant content reference security components that are standard for card-not-present acceptance:

• 3D Secure authentication flows

• PCI DSS and SSL for data protection

• Tokenization via stored cards to avoid handling raw PANs directly

In production, Param requires secure HTTPS connectivity and IP allow-listing for API access. This operational control helps reduce the attack surface for server-to-server calls. Merchants can also use the hosted page approach to reduce PCI scope on their own infrastructure.

Settlement, Pricing Model, and Timelines

Param markets a next-day payout experience after commission deduction for approved merchants. It also communicates application review and activation timelines targeted at roughly 24 hours, subject to documentation and risk checks. Param’s content highlights a transparent approach to fees, stating there are no setup or monthly fees for Virtual POS. Commission rates vary by merchant profile, card program, and installment structure; Param materials also note potential commission advantages for businesses using a Param Business Card.

Integration Paths and Developer Experience

APIs and Environments

Param provides SOAP-style API methods for payments, pre-authorization, refunds, transaction queries, reconciliation, and rate management. Production access requires registering outbound IP addresses. A dedicated test environment and test cards are available, along with a Postman guide to speed up API exploration.

E-Commerce Plugins

For fast go-lives, Param maintains plugins and setup guides for major platforms, including:

• WooCommerce

• Magento

• OpenCart

• PrestaShop

• NopCommerce

The plugin documentation covers how to obtain API credentials from Param’s internet branch, configure installment options, and process 3D Secure transactions. For custom storefronts, Param supplies API references and examples across common server environments.

Reporting and Reconciliation

Beyond transaction initiation, the API includes methods for pulling daily summaries, reconciliation details, and per-transaction queries. These endpoints help finance teams match bank settlement lines, review installment economics, and manage refunds.

In-Person and Mobile Acceptance

Param’s ecosystem also addresses in-person scenarios. Merchant content on Param’s channels explains Mobile POS as a smartphone or tablet-based point of sale option for taking cards on the go, which can be relevant for field sales, delivery, and events. For merchants that need a complete solution spanning online and in-person acceptance, Param lists product pages for Mobile POS and Physical POS in its business catalog. Confirm device, network, and certification specifics with Param during scoping.

When Param Fits Best

Param is aligned to merchants that:

• Sell online in Turkey and need installments across major card programs

• Want one agreement instead of many bank relationships and integrations

• Require a fast path to production via plugins and hosted payment pages

• Need marketplace primitives for sub-merchant onboarding and split payouts

• Plan to support recurring billing or stored cards for returning customers

• Prefer next-day settlement to improve cash flow after going live

Conclusion

Param delivers a focused Virtual POS and marketplace toolkit built around one-contract bank coverage, installments, tokenization, and next-day settlement positioning. Developers can move quickly with plugins and a complete API surface that includes pre-authorization, refunds, reconciliation, and hosted checkout options. For Turkish e-commerce and platforms that depend on installments and fast settlement, Param is a pragmatic fit.
