I was given a task to migrate Salesforce Solutions to Zendesk Forums. I realised the only way that you can export Solutions from Salesforce, is to generate a report and export the results as .xls or .csv format.
I selected only Content Title and Solution Description and exported to a csv file. I chose .csv format as I had a feeling it could be comparatively easier to code to import.
Create a forum in Zendesk where you want the Salesforce solutions to be dumped and find it’s forum id via the URL.
Replace it in the script that I wrote and run it to to read this csv file and import into Zendesk.
You may find the script here : https://github.com/ijeyanthan/salesforce-solutions-to-zendesk-forum
To extend the functionality, visit developer API docs http://developer.zendesk.com/documentation/rest_api/forums.html for the list of possible JSON requests available in Zendesk.
