Workflow preview
This workflow demostrates the use of the option "Propagate modified loop variables" available in Loop End nodes. The workflow repeats sending GET requests (where the maximum number of results is limited to 40) to get all the relevant book authors and titles for a provided search term untill the starting index of an item (a book) is larger than the total number of available items for this search term. The workflow demonstrates the difference for external, injected, and internal variables when the propagation of modified variables option is on.
