NOTE:
The symbol √ indicates that the carrier is supported by software.
- DSC APIs do not support inserting or extracting watermarks for OBS data. To perform watermark-related operations on OBS bucket data, store the data to the local PC and then call DSC APIs. The watermarked document will be returned in the response body.
- For more details of API constraints, see the API Description section.
