You can use our official [Postman collection](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/overview) to get started with Nutrient DWS Processor API with the click of a button. Use this guide when you want the official Postman collection for Nutrient Processor API, need the fastest path from API key to a working request, or want to explore multiple Processor API task endpoints before writing integration code. If you need broader DWS context while testing requests, continue to the [Processor API overview](/api/processor-api/), the [REST API reference](/api/reference/public/) for endpoint documentation, the [dashboard getting-started guide](/guides/dws-processor/getting-started.md), or [Processor API pricing](/api/pricing/processor-api/). Alternatively, you can [download the collection as a zip file](https://www.nutrient.io/assets/guides/dws-processor/dws-processor-api-postman-1de21c03234faf2e4a3d4762f4606913.zip) to import it locally into Postman. ## Get started 1. Create an account in [Nutrient DWS API dashboard](https://dashboard.nutrient.io/sign_up/?product=processor) and receive 200 free credits to start testing. 2. In Postman, create a `variable` named `DWS_PROCESSOR_API_KEY` and paste your key as its value.![Screen capture of the Postman window with the Variables section open](@/assets/guides/dws-processor/variable.png) 3. In the **Authorization** tab, set the type to **Bearer Token** and enter `{{DWS_PROCESSOR_API_KEY}}` as the token.![Screen capture of the Postman window with the Authorization section open](@/assets/guides/dws-processor/auth.png) Make sure each request includes the following header: `Authorization: Bearer {{DWS_PROCESSOR_API_KEY}}`. For more information, refer to the [variables in Postman](https://learning.postman.com/docs/sending-requests/variables/variables/) guide. 4. Choose a request and click **Send** to get started. > We include example files with the collection so that you can try different examples right away. All files are already hosted and accessible via public URLs.![Screenshot of the Postman interface with a merge request example selected and the rendered PDF preview displayed in the response panel](@/assets/guides/dws-processor/result.png) ## Key features and tools ### PDF editing tools - [Merge PDFs](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/edvzwp4/merge?tab=body) - [Split PDFs](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/am144rs/split?tab=body) - [Delete pages](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/0u4d2wt/delete?tab=body) - [Flatten PDFs](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/0ip4ydp/flatten?tab=body) - [Duplicate pages](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/07ea627/duplicate?tab=body) ### OCR operations - [Basic OCR](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/9x0zszy/basic?tab=body) - [Merge and OCR combined workflows](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/whrrc16/merge-and-ocr?tab=body) ### Watermarking - [Text and image watermarking](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/0crycw8/text-watermark?tab=body) - [Multiple overlay support](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/cur65dl/multiple-watermarks?tab=body) ### File conversion - [HTML to PDF](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/yg94vz9/html-to-pdf-basic?tab=body) - [Office to PDF (Word, Excel, PowerPoint)](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/a6wda5f/docx-to-pdf?tab=body) - [Image to PDF](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/nfs2lwj/png-to-pdf?tab=body) - [PDF to image](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/y1eu1x8/pdf-to-png?tab=body) - [Office to image](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/2qy3fs1/office-to-png?tab=body) - [HTML to image](https://www.postman.com/nutrient-dws-api/nutrient-dws-api/request/4n67ig0/html-to-png?tab=body) [Sign up and get started today](https://dashboard.nutrient.io/sign_up/?product=processor)! --- ## Related pages - [Nutrient DWS MCP Server](/guides/dws-processor/getting-started/mcp-server.md) - [Create sample HTML.](/guides/dws-processor/getting-started.md) - [Zapier integration](/guides/dws-processor/getting-started/zapier-integration.md)
