***Note:***\
\&#xNAN;*These details will be provided by Greytrix to the client.*
Click on **Save** button to authenticate details. If the connection is successful then "**Success Flag**" will be checked into Configuration grid. If there is any error with connection, then Success Flag will NOT be checked and Authentication error will be displayed into “**Authentication error**” column.
**Note:**\
If a user faces any issue while connecting to GUMU or syncing the process list, make sure the **“Default Value”** is set for **“GUMU Subscription ID”** in **System Settings**.
The **“Default Value”** is a unique number that the user receives after successfully subscribing to GUMU.
To add the GUMU Subscription ID, follow these steps:
1. Go to **System Settings** and Search for **“GUMU Subscription ID.”**
2. Open the settings and enter the value in the **“Default Value”** field, and click **Save**.
Once done, refresh the Creatio screen and try the process again.
