When I try to configure the AGA OpenText content server with SharePoint in development environment it get the below error.
Error: Could not resolve API Name.
The error means that a LAPI function called by AGA (from the SharePoint side) was not implemented on the connected CS. Didn't you forget to update the AGA CS module after you updated the SharePoint application? They both should have corresponding versions and sometimes an AGA patch needs a module update too.
If you use multiple SharePoint (and AGA) versions, install the newest AGA CS module; the CS module is backwards compatible.
