Importing APIs from OpenAPI/Swagger
What Is OpenAPI/Swagger?
OpenAPI (formerly known as Swagger) is a standardized specification format used to describe an API's endpoints, request formats, and responses, allowing tools like Postman to automatically understand and interact with an API.
Why Import an API Definition?
Instead of manually creating each request one by one, importing an OpenAPI/Swagger file lets Postman automatically generate a complete collection of requests based on the API's documented structure.
Steps to Import an API
| Step | Description |
|---|---|
| 1. Click Import | Found at the top of the Postman sidebar |
| 2. Select File or Link | Choose an OpenAPI/Swagger file or paste a URL to the definition |
| 3. Review Generated Requests | Postman creates a collection based on the imported definition |
| 4. Save the Collection | Store it in your workspace for future use |
Benefits of Importing
Importing from OpenAPI/Swagger saves significant setup time, reduces manual errors, and keeps your Postman collection closely aligned with the API's official documentation.
With APIs imported directly from OpenAPI/Swagger definitions, the next step is learning how to send data through the request body, including file uploads.
