Create URL in Shortcuts app that contains two variables

I don't have access to your particular website but I simulated the same using flightradar24.com, which presents the longitude and latitude in the same format:

I ran successfully this shortcut several times on a Mac (macOS Sequoia 15.7.2) and an iPhone (iOS 26.1).

In your 1st screenshot, the variable “URL” in the “Get Content of URL” action is undefined. Delete the variable and select the appropriate variable (the fist action.)

I’ve asked the hosts to mask the API key in your last 2 screenshots but I took the opportunity to test your specific website. (I’ll remove that information from my device once we find a solution to your issue.)

I believe you’ll be running into an authentication issue:

I ran this shortcut directly in the Shortcuts interface so the last thing on the screenshot is the output of the “Get Content of URL” action. The output shows an authentication error.

I don’t know what you need to do to authenticate yourself on this website and I don’t know if you can add your credentials to the URL. This would be a question for the website support team.

It works when you make the updated text from the Replace action the new URL, not the thisURL variable, and providing the original URL syntax and API key are correct:

Thanks again. How do you know "the variable “URL” in the “Get Content of URL” action is undefined?"

The variable URL is red, which means it does not refer to the URL action in the 1st screenshot:

The action "Get Contents of URL" can take either a variable (from the URL action, as in my example above) or a string-defined value, as shown below. In both cases, the URL has to be in a proper form/syntax as per HTTP and the website:

Note that "Get Contents of URL" is to return the content of the web page (as "data"), i.e. nothing is displayed in Safari. You have to then further process the resulting data to extract things of value to you. This can be cumbersome but, in some instance, easy if for instance the website returns only pure data (often in the form of json data.)

There are several websites that can help you with understanding Shortcuts, this one from Apple for instance: Intro to Shortcuts on Mac - Apple Support. But do not be fooled: it takes practice and trial and error to get a shortcut to work as desired. The learning slope is rather steep. I found that the best way to learn is through examples.

Please do send me your shortcut. I'll take a look at it and make suggestions. You can share a shortcut through iCloud. On the Mac for instance, right-click your shortcut, choose Share > Copy iCloud Link, validate by clicking the Share button. This will put the iCloud link in the clipboard. Paste the link to your reply here so that I can download it.

Could you also share how you intend to use the shortcut? I'm gathering from the link that the website gets some kind of weather data. Do you need to process the data (extracting some specific information, for instance)? Do you need to display the data somewhere? Do you need to save it?

Don't hesitate to post a screenshot of the actual content of the webpage as displayed in Safari when you normally use Safari to view the data (mask any personal information). This will give me an idea of what the data looks like.

Here is an example of what you could do: Get Dewpoints.

Note that I’m not using intermediate variables. I only renamed the original variables (“Dewpoint”) in order to differentiate them.

To rename a magic variable, tap it (here for instance “Dewpoint” in the Show Notification action) and type in a name:

Yes, that would work too.

No need to add extra variables. You can use "Get Current Weather" and "Get Details of Weather Conditions" to obtain the dew point (or any other weather-related data):

Maybe this will work for you…
