Let’s explore the code snippet in more details.

SlidesApi slidesApi = new SlidesApi(clientID, clientSecret);

Create an object of SlidesApi class where we pass the client credentials as arguments.

slidesApi.CreateSlide(sourcePPTX,null, newSlideIndex);

Call the API to add blank slide at given index. If the position parameter is missing, then the slide is added to the end of the presentation.

The sample PowerPoint used in above example can freely be downloaded from 3D PowerPoint Hubble Telescope model.pptx.

How to Add Slide in PowerPoint using cURL Commands

Adding PowerPoint slides can also be achieved using cURL commands in combination with Aspose.Slides Cloud. With the RESTful API provided by Aspose.Slides Cloud, you can make HTTP requests using cURL commands to interact with the PowerPoint presentations. This approach offers flexibility and allows the integration with various programming languages and platforms. So, whether you prefer using cURL commands directly or incorporate them into your scripts or applications, you can leverage the power of Aspose.Slides Cloud to efficiently manage and manipulate the PowerPoint slides.

Firstly, we need to execute the following command to generate a JWT access token:

curl -v "" \
 -X POST \
 -d "grant_type=client_credentials&client_id=bb959721-5780-4be6-be35-ff5c3a6aa4a2&client_secret=4d84d5f6584160cbd91dba1fe145db14" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Now execute the following cURL command to add a new slide at index # 4.

curl -v "{sourcePPTX}/slides?position=4" \
-H  "accept: application/json" \
-H  "authorization: Bearer {accessToken}" \
-d {}

Replace sourcePPTX with the name of an input PowerPoint already available in cloud storage, and accessToken with JWT access token generated above.


In conclusion, the ability to add PowerPoint slides programmatically opens up a world of possibilities for automating and enhancing your presentation workflows. Whether you choose to utilize the Aspose.Slides Cloud SDK for .NET or leverage cURL commands with Aspose.Slides Cloud, you have powerful tools at your disposal to seamlessly integrate slide addition functionality into your applications and systems. This capability allows you to dynamically generate presentations, and efficiently manage slide content. Nonetheless, by harnessing the power of these technologies, you can streamline your PowerPoint creation process, save time and effort, and deliver appealing and engaging presentations.
