A security error has occurred. Make sure you are signed into Microsoft Dynamics CRM and try again in Click Dimensions.

We had this issue in past when we started getting below error in most of the entities of Click Dimensions.

The issue can occur if the password would have expired or changed for the Service Credentials account of Click Dimensions.

Go to Settings à ClickDimensions Settings à Service Credentials.

In our case it wasn’t changed but we were still getting the issue. The only way we were able to fix it was to specify a different account for the Service Credentials.

Hope it helps.

The remote server returned an error: (403) Forbidden while sending SMS from Click Dimension

We got the below while sending SMS from Click Dimension. We were using Bulk SMS as our SMS connector for Click Dimension.

When we opened the Text Messages record we figured out that we were getting “The remove serve returned an error (403) Forbidden.

This occurred because we had our credit with Bulk SMS already consumed.

The issue got fixed when bought the credits again with Bulk SMS.

Hope it helps.

Hello friends, I found a weird issue during a USD configuration, I was getting error message “Index (zero based) must be greater than or equal to zero and less than the size of the argument list“, when I was trying to assign a custom entity record to a different agent (systemuser) using USD action call.

Issue: action call was failing with error message “Index (zero based) must be greater than or equal to zero and less than the size of the argument list“, complete error message was


Action Call# 20
