Fully-qualified function names
Each function uploaded by your users has a unique name called a fully-qualified function name, or FQFN. The string representation of an FQFN is as follows:
com.example.nawronuq98hqwekj198fkljbeco#default::record-event@v1.0.0
|_____________|___________________________|________|____________|______|
 Environment          User ID             Namespace  Function   Version
Here's a breakdown:
- Environment: your company's reverse domain; 
com.example - User ID: The unique value that your application uses to identify your users within your system; 
nawronuq98hqwekj198fkljbeco - Namespace: The namespace this function belongs to; allows for separated groups of functions based on product needs (see Namespaces ); 
default - Function:  The name of the function as chosen by the user; 
record-event - Version: The version of this function (incremented each time a user updates this function); 
v1.0.0 
Environment name
The domain of your email address should match the environment you
configure for Compute, i.e. if your email is laika@example.com, your
Compute environment would be called com.example.
FQFN URLs
To execute a function in Compute you will use a URL representation of FQFN. To reference an FQFN by URL, use the following pattern:
/{environment}.{userid}/{namespace}/{function}/{version}
Example:
com.example.nawronuq98hqwekj198fkljbeco/default/record-event/v1.0.0
