postman set collection variable code example
Example 1: postman environment variables
pm.environment.set("variable_key", "variable_value");
Example 2: collection variables postman
Only accessible within the same collection and
can not be accessed anywhere else
COLLECTION variables are available throughout
the requests in a collection and are independent
of environments, so do not change based on the selected environment.
I use collection variables when
I use single environment like url details.
We can refer to the variable by using {{}}(double curly brace)
and it can be used anywhere
Example 3: defining collection variables
Use pm.collectionVariables to define a collection variable:
pm.collectionVariables.set("variable_key", "variable_value");
