# Parameter restrictions for actions in the Amazon Connect Flow language
<a name="flow-language-actions-parameter-restrictions"></a>

There are several restrictions on parameters. Here's what they mean:
+ Must be defined statically. This means that JSONPath cannot be used at all in this value.
+ Must be defined statically or as a single valid JSONPath identifier. 

  If JSONPath is used, it must be the entirety of the value; you can't specify an input of "My name is \$1.Name". Further, the JSONPath must be valid - \$1.Attributes.stuff is okay, \$1.BadValue is not okay because there's no "BadValue" path on the object used by flows.
+ May be defined statically or dynamically. Anything goes. A value of "My name is \$1.Name" is fine here, as well as a fully static value.
