What are Pipeline Variables?
Each automation pipeline can have optional variables defined. A pipeline variable can be declared at the very beginning of a pipeline in the vars: section and then used inside the automation pipeline using the Pipeline Expression Language (PEL) and the vars scope. Here is an example:
vars:
firstName: "Petra"
pipeline:
- body.set: "My first name is: ${vars.firstName}"
Which produces an output like this:
My first name is: Petra
As you can see, the variable can be read using the PEL by defining the vars scope and its name separated by a dot:
${vars.firstName}
Note: It is good practise to declare every variable in the vars: section at the very top of your automation pipeline so it is more clear which variables are in use inside the automation pipeline.
