Path parameters (CHAD)
View Parcel (CHAD) overviewThe basics
Path Parameters are set using substitutions within a dedicated endpoint Library. They're used by CHAD to access resources at remote (external) endpoints.Assigning a parameter is done using PV_.
In this example we've got two path parameters;
PV_england | |
---|---|
PV_wessex |
NOTE: Path parameters can only be set on endpoint calls made by Parcel not to it.

Assigning path parameters
Okay, now lets explore how to set the values for the path parameters discussed.PV_england | |
---|---|
PV_wessex |
Assign a value
Here we're using the Endpoint Library itself this works just fine when you've only a handful of parameters. Generally speaking we'd recommend using two seperate Library for both the endpoints & parameters.What we've done is change the values to something easily manipulatable within a your Conversation (deadCL programme).
PV_england | becomes$_england |
---|---|
PV_wessex | becomes$_wessex |
You may also set permanent path parameters as shown below the two variable values.
