Thanks i was able to post data into Appian from SharePoint using the flow automation but now its fails when PATCH/PUT/Merge is used to update the same SharePoint site when the data in appian is changed. Tried using the connected system but keep getting

SharePoint returned a 400 HTTP error

error-result-guidance

SharePoint returned the following error code: -1, Microsoft.SharePoint.Client.InvalidClientQueryException The type SP.ListItemEntityCollection does not support HTTP PUT method.

If i use POST then i'm getting following error

SharePoint returned a 400 HTTP error

error-result-guidance

SharePoint returned the following error code: -1, Microsoft.SharePoint.Client.InvalidClientQueryException A node of type 'StartArray' was read from the JSON reader when trying to read the start of an entry. A 'StartObject' node was expected.

You will probably get better information on that from a sharepoint/microsoft forum, as calling Appian should be like any other web service. Doing a quick search shows that it looks possible that sharepoint workflows can call a web service, like the one you said you made already.

Yes I have created that as well but how will SharePoint post data to appian? I have exposed the site via API but I don't see any option for SharePoint to post the data would Microsoft Flow work ?

Hello,

It sounds like what you want to do is create a web API in Appian, and then expose that to your Sharepoint.
