+You cannot pass [Secure and Unsecure Configuration](write-plug-in.md#pass-configuration-data-to-your-plug-in) in to the Main operation Plugin for the CustomAPI.
 
-**Workaround**: Do not register the plugin, where you want send the secure and unsecure configuration, during CustomAPI creation through UI. Register the plugin as a `PreOperation` or `PostOperation` plugin through PRT and you should be able to set the configuration values as any other plug-in. More information: [Register Plug-in and set configuration data](register-plug-in.md#set-configuration-data)
+**Workaround**: Rather than associate the plug-in with the Custom API, register the plug-in on the `PostOperation` stage using the Plug-in Registration tool (PRT). This way, you can [specify configuration data in the `PostOperation` plug-in step as you usually do](register-plug-in.md#set-configuration-data).
+
+For this to work, you must configure your Custom API to enable **Sync and Async** [custom processing step types](#select-a-custom-processing-step-type) when you create the custom api. You can't change this after you create it.
