# Welcome

Here, you will explore how to use the Paywall service, its features, and the functionalities it provides.\
With Paywall, you can perform payment transactions quickly and successfully. Instead of integrating each payment provider from scratch, you can easily access all provider capabilities through a single point via Paywall and accelerate your integration process.

**Integration and SDK Support:**\
You can easily integrate the Paywall service into your products using any programming language. Paywall offers RESTful-based integration capabilities and also provides SDK support.\
If the SDKs offered by Paywall do not fully meet your requirements, you may contact us.

**Security and Authorization:**\
Paywall API uses a security key–based authorization mechanism. To complete an integration, a merchant-specific Public API Key and Private API Key must be used. These credentials are provided to the merchant by Paywall once the onboarding process is completed.

Thanks to its PCI DSS compliance, Paywall provides the level of trust and security your business needs.
