How to Use the PostExport API with SDKs

PostExport API Specification

The OpenAPI Specification defines a publicly accessible programming interface and lets you carry out REST interactions directly from a web browser.

All requests must include a valid OAuth 2.0 Bearer token in the Authorization header. The example below shows how to call the API with cURL and upload a workbook using multipart/form‑data.

curl -X POST "https://api.aspose.cloud/v3.0/cells/export?objectType=chart&format=tiff" \
  -H "Authorization: Bearer {access_token}" \
  -H "Accept: multipart/form-data" \
  -H "Content-Type: multipart/form-data" \
  -H "x-aspose-client: Containerize.Swagger" \
  -F "File=@/path/to/your/workbook.xlsx"

Use Aspose.Cells Cloud SDKs

Using an SDK is the best way to speed up development. An SDK takes care of low‑level details and lets you focus on your project tasks. Please check out the GitHub repository for a complete list of Aspose.Cells Cloud SDKs.

The following code examples demonstrate how to make calls to Aspose.Cells web services using various SDKs:
