# Invoking an action
The syntax here is almost identical to that of the `wsk` CLI.
```
-? (wskdb) invoke actionName -p param1 value1 -p param2 value2
+(wskdb) invoke actionName -p param1 value1 -p param2 value2
```
If you haven't yet attached to the action you are invoking, the invocation will proceed as if you weren't in the debugger, and had issued a blocking invocation from the CLI.
