Everything you need to know.

Common programming languages like Python, PHP, Ruby, Java, and Node.js are often used to integrate payment APIs. Many payment APIs support RESTful standards, which means they can work with different programming languages. At Metizsoft, we use these languages and frameworks to help you integrate payment APIs that fit your business needs.
Payment APIs handle pending and failed transactions via their error-handling mechanism. They provide real-time feedback on the transaction status, often through response codes or messages. These codes or messages detail the reason for the pending failure, such as insufficient funds, an expired credit card, or a downed banking server.
Yes, we use modern technologies like AI, ML, and blockchain to enhance APi capabilities. Our payment gateways support multiple currencies and various payment methods, facilitating global business expansion and catering to customers from diverse countries.
Integration times for payment gateways depend on the resilience and complexity of your existing systems and the chosen gateway. Typically, this process can take from a few days to several months. At Metizsoft, we act according to the changes and requirements, trying to finish the project on time.
Yes, we do! We analyze the business model and prepare a strategy that perfectly aligns with its uniqueness. Our developers then customize the checkout flow and payment pages and integrate additional features such as subscription billing or recurring payments.
You can monitor the integration process of your web and mobile app. Flexibility is one of our key strengths, and we genuinely uphold this commitment. We have made our API integration process transparent for our clients, allowing them to participate anytime, request updates, and suggest changes as needed.
