we are in the process of evaluating the Cloud API to see if it fits our needs.
We are trying to use the smartmarker capability, but it is not clear as to how to use it:
We created an example that calls the https://api.aspose.com/v1.1/cells/genericTemplate.xlsx/smartmarker with the appSID and signature in POST where the body is an XML representing the information (see both attached).
Both approaches are right, if you will not specify the xml file path, then you will have to specify it inside the body.
This documentation article shows it how to make use of this API. In this article, you will also be able to download the Designer Spreadsheet and see the XML used to specify data.
