We have to update value of a smartsheet Cell. This Cell contains Hyperlink to a different sheet. Hyperlink URL is assigned. We want to update this cell value by Smartsheet API C# SDK.
Here is the API Documentation that goes through how to update a cell using C# SDK.
You'll notice that there is a Hyperlink Object listed (see the documentation here), which is where you will need to provide the sheet ID to maintain this current hyperlink.
If you've followed the steps in the articles above, it would be useful to see an example of how you've written out your instruction and any error messages you're receiving (but please block out any sensitive data).
