![What is a unified API?
A unified API is an API that brings together multiple APIs and presents them as a single API service. With a unified API, developers can integrate their applications with multiple SaaS applications using a single, consistent interface.](https://www.globalnerdy.com/wp-content/uploads/2024/05/what-is-a-unified-api-600x400.png)
Last week, I revised one of Unified.to’s earliest articles, An Overview of Unified APIs, rewriting it as What is a Unified API?
In addition to updating the text of the article, I also created some explainer graphics to liven it up and save the reader from being hit with just a wall of text. Those graphics are what you see in this article — enjoy!
![Endpoints in a unified API
A unified API should have unified or common endpoints for specific categories of integrations. Most API solutions don’t actually offer this.](https://www.globalnerdy.com/wp-content/uploads/2024/05/endpoints-in-a-unified-api-600x400.png)
![Data models in a unified API
A unified API should unify data models from different APIs that represent the same thing
into a single data model with enough properties to satisfy most use cases.](https://www.globalnerdy.com/wp-content/uploads/2024/05/data-models-in-a-unified-api-600x400.png)
![Authorization in a unified API
A unified API should have a method for authorizing access to customer data that is easy to use. Ideally, it should provide an authorization component that can be embedded in applications.](https://www.globalnerdy.com/wp-content/uploads/2024/05/authorization-in-a-iunified-api-600x400.png)
![Webhooks in a unified API
A unified API should abstract all of the complexities of handling those vendors that don’t support webhooks and provide a unified webhook experience.](https://www.globalnerdy.com/wp-content/uploads/2024/05/webhooks-in-a-unified-api-600x400.png)
![Unified API breadth and depth
Breadth refers to the number of APIs supported by a unified API. Depth refers to the number of fields supported by a unified API’s data model.](https://www.globalnerdy.com/wp-content/uploads/2024/05/unified-api-depth-and-breadth-600x400.png)
