Dynamic API Query

You can point the end-user to the Advanced Search page where they can enter From and To dates. The main idea is to show them some other page first before taking them to the List page.

Thanks Sergey. I think that would work to search the API response. I'd like to be able to adjust the parameters into the URL prior to querying the API.
In Excel I calculate the query URL and use the WEBSERVICE() function to run the query (see https://www.xlsql.net/intro.htm#sheet-3 for example).
Is it possible to emulate this dynamic approach in PHPRunner?

Your understanding is incorrect. Data entered on the Advanced Search page can be passed to the REST API in order to form a dynamic request.
Use 'Insert variables' button:

Which is exactly why you get the big bucks (hopefully). Yet another amazing PHPRunner capability, see it in action...

Click the "TMDB - Search By Title" menu option and enter some text to dynamically search the TMDB movie database (600,000+ records).
The only outstanding issue is the error caused by submitting an empty query string or clicking the "Show All" button.
Is there a way to have it error out a little more gracefully if this occurs?
Thanks!

Sorry, never mind, eventually I'll learn to check the manual first. Working great now.
Thanks!
