Addin files

Relevant for: API testing only

The addin file provides the references for the activity you are defining. The file is in XML format and contains information such as activity names, dependencies, and runtime DLLs.

The addin file should be located in the installation directory under the addins\CustomerAddins\<addin_name> folder, together with the signature file. The addin file must have an .addin extension.
