Sharepoint Integration Issue

...LDER),

If I change "usePerUserCredentials" to true(), the I get error "An error occurred while attempting to store into variable local!download. Details: You do not have credentials configured for this system [key=sharepointcredetials_rishu]. Please navigate to the Third-Party Credentials page in your Settings and provide credentials for this system." I am already setting the credentials on "Third Party Configurations" (Attached snaphot) & with same username and password, I can login into our sharepoint. The host name I am using is "companyname.sharepoint.com". can anyone guide where I am getting it wrong please?

I think you must make use of 3 third-party credentials parameteres. Based on documentation, you should have the following 3 params:
1. Username
2. Password
3. Domain

Also, if you have unchecked the box under the parameters then you should set the connector parameter as noted below:
"usePerUserCredentials : false"

Thanks anastasiosk, Can you please tell me what should be the domain name?

As i see, you are trying to integrate Appian with a local sharepoint implementation (not a Sharepoint Online - Cloud). So, if this is the case, you have to find the domain of the sharepoint user that you are trying to connect. For example. if you are at an organization 'MyOrganization" then you may have this full name --> "MyOrganization\\Username".

If you can't find the domain, then just add the parameter on the third party credentials and just leave it blank. Then try to see if the connection is succesfull !

*Keep in mind that the user you are trying to connect has appropriate access to the sharepoint site and resources.

Thank for update. I tried it as told by you & now I am encountering below error:

[http-/0.0.0.0:8080-7] ERROR com.appiancorp.core.expr.DelayedWriteContext - An error occurred while attempting to store into variable local!download.

I was able to fix that issue & when I moved forward,I got the following error:

Hi All, I am facing this same issue now. Do we have any solution for this problem. Please share your inputs on this.
