Not Sure How to Approach Payment Gateway Integration? Start Smart with a Proven Approach!

We’ve spent almost two decades developing high-scale B2B and B2C eCommerce and patent-processing solutions that include wide-ranging payment functionality, like: 

The scale of our products and the resulting need to integrate them with scores of diverse payment systems have given us an ultimate grasp of the payment gateway integration process. 

Our developers are equally skilled in employing the Direct Post, Hosted Payment Gateway, and Integrated payment gateway integration methods and are always prepared to use the one that fits best. They are also conversant with using SDKs. Furthermore, our R&D team has come up with a proprietary payment gateway integration framework to expedite the integration and cut the payment gateway integration cost.

Payment Gateway Integration Services

  1. Payment Gateway API Integration

    For years, we’ve been heavily engaged in integrating our high-scale payment gateway solutions with payment systems and payment processors to support the ever growing business needs of our industry-leading eCommerce clients. 

    This has given us a high level of competence in developing succinct and secure payment APIs we use in our integrations. We also have experience with APIs from other software vendors.

  2. Integration with Multiple Payment Methods

    Due to the breadth of our payment gateway integration efforts, our developers have acquired strong familiarity with, and experience in integrating an array of payment methods. 

    More specifically, we can integrate with the major card networks, like Visa, MasterCard, and others, and digital wallets, like PayPal, Apple Pay, Google Pay, and others. Besides, we can also implement bank transfers, alternative payment methods, cryptocurrencies, and ACH payments.  

  3. Payment Gateway UI Optimization

    We are versed in developing payment gateway GUIs that are parts of user journeys and not additional barriers for our clients’ customers.

    Despite the need to contain many details, our payment gateways are always designed to provide hassle-free UX and serve as a continuation of our clients’ marketing efforts.

  4. Security Features Implementation

    Security is a topmost priority we always pay utmost attention to. 

    Our developers can skillfully implement the whole range of security means that are usually used to secure the payment gateway-related interactions, including TLS/SSL encryption, user authentication, tokenization, and fraud prevention.

These payment systems hail from different geographies that include the U.S, Canada, Denmark, the Netherlands, Poland, Greece, the U.K,  Norway, Spain, the Philippines, and the UAE.  Quite often, we’ve had to add some locally-preferred payment methods and deal with new related challenges.

  2. Comprehensive Compatibility Analysis

    Prior to making a decision on the integration of a client’s solution with a payment gateway, we conduct thorough compatibility analysis to make sure this gateway fills your bill. 

    We check such factors as the payment methods, currencies, and security and compliance standards the gateway supports, as well as some others.

  3. Ensuring End-to-End Regulatory Compliance

    Our development team takes a serious and all-round approach to ensuring regulatory compliance. 

    In each specific case, we determine all the applicable compliance required, mobilize the corresponding expertise, and see to it that this expertise is applied comprehensively, thoroughly, and consistently.
