Most developers have faced the challenge of working with complex integrations from various data sources. From setting up databases to integrating external services, these tasks can take hours — sometimes even days. When a project demands connecting multiple services at the same time — like databases, REST APIs, payments, and authorization — even skilled developers may waste a lot of time dealing with configurations and long-winded documentation.
This is where Retool steps in — a powerful platform that lets you combine all these systems effortlessly, offering seamless integration with a variety of services. Retool simplifies the process of integrating with different data sources, including both databases and external APIs.
Here’s a look at some commonly used database integrations:

Clear and Comprehensive Documentation
Another factor that makes Retool so easy to work with is its exhaustive yet well-structured documentation. It provides clear, step-by-step instructions for connecting each supported data source. Thanks to this, even the most complex integrations become intuitive, allowing developers to focus on what really matters — building the application itself, not getting lost in configuration.
Example: Integrating PostgreSQL and REST API
For example, let’s say you need to connect PostgreSQL with read-only access for secure data retrieval, while at the same time using a REST API to handle write operations in the same database. With just a few clicks, you can connect these data sources and immediately start working with them through Retool's intuitive built-in GUI.
Connecting to PostgreSQL is incredibly simple. Just enter your database credentials — host, port, database name, and user authentication — and Retool takes care of the rest (Here’s a link to a PostgreSQL connection example). Once connected, you can easily choose the most comfortable approach for your workflow, whether you prefer the ease of the interface or the precision of manual SQL.
For REST APIs, Retool provides equally seamless integration. Once the API is connected, you can manage the resource with GET, POST, PUT, PATCH and DELETE requests (Here’s a link to connecting REST API example). Retool makes handling API requests as easy as interacting with a database.
Yes, it's that easy!
Why Retool Saves You Time and Effort
Without Retool, you could easily spend hours trying to configure each integration by hand, sifting through bulky documentation, and troubleshooting countless minor issues. This can delay critical tasks or make them take much longer than they should — time that could be better spent on more important work.
Summary
In today’s development world, flexibility and speed are KEY. With Retool, you can effortlessly integrate databases, REST APIs, authorization systems, notifications, caching, and even AI tools — all in one platform. These integrations help you build a scalable and adaptable ecosystem that grows with your business, ensuring your system is ready for future challenges. You also focus on delivering value to your users instead of spending time on manual setups. Whether you prefer a simple interface or more custom control, Retool adapts to your workflow.
In short, Retool helps you build smarter, quicker, and more efficiently, making sure you’re equipped for any development challenge.
