I want Ruby to use the external API to view the pickup status.

Prerequisites/What you want to achieve

Ruby uses an external API to create a web application that allows you to check the pickup status of the delivery.
I was able to link the API, but I don't know where and how to fix it because invalid API is displayed in View.If the code editing method and the external API implementation method are incorrect, please let me know.

External API being used: Tracking more
Write the code and refer to the page

I haven't received a reply to your comment yet, but index.html.erb in CollectingStatusController is assumed to be the view of CollectingStatusController in and so on.

The biggest problem is this line of index.html.erb.

<form class="index" action="https://api.trackingmore.com/v2" method="post">

This means that the browser sends the request directly to the API server, but the browser does not convert the post request to JSON, nor does it put the API key in the HTTP header.Since you are sending a request without an API key, it appears that the API server has returned a response to the browser with meta information {"code":4001, "type": "Unauthorized", "message": "Invalid API key"}.

(If you type https://api.trackingmore.com/v2 directly into the URL window of your browser, you should see the same response.)

You are writing the code little by little while checking the movement here and there, but the current code is not enough to test whether the Ruby API call works.You have to write a code that uses the API calling class (Trackingmore) as the Ruby side code.

Try replacing the previous line with the following:

`index.html.erb`

...
<form class="index" action="<%=url_for:controller=>'collection_status',:action=>'search'%>"method="post">
...

(The controller name and action name may need to be rewritten depending on the actual web application configuration, but the following assumptions are made.Depending on the actual configuration, it may need to be replaced accordingly.)

The browser now sends a request to the CollectingStatusController and requires a method to handle it.

However, you should modify the Trackingmore class nested inside the CollectingStatusController before you touch collecting_status_controller.rb.

Rails will always have the app directory, but create the lib directory under it (if you already have a directory for similar purposes, you can do so), and then place the trackingmore.rb on one line below.

`app/lib/trackingmore.rb`

...
    headers={'Content-Type'=>'application/json', 'Trackingmore-Api-Key'=>'Actual API Key'}
...

After this, you must add the search method to collecting_status_controller.rb.(Of course, Trackingmore class definitions are deleted.)

The whole thing will look like this.

`collecting_status_controller.rb`

...

class CollectingStatusController<ActionController::Base

  def search
    # Create postData by extracting parameters from params (validate and process errors if necessary)
    #post_data=...
    # Prepare the URL of the service you want to use as a string
    url='https://api.trackingmore.com/v2/trackings/updatemore'
    # The way of calling on the reference page is almost the same.
    tracker = Trackingmore.new
    res=tracker.tracker(url, post_data, 'POST')
    # Also check res.code and if there are no errors, analyze res.body as JSON.
    #json=...
    # You may need to check if the contents of json are errors.
    #...
    # Create data to pass from analyzed JSON to view
    # @search_results=...
    # Display view for display
  end

end

post_data is quite difficult to create request parameters, but if you just want to check if the API is calling well, you can create dummy data for now.You will also need to create a result-checking view (search.html.erb), but it depends on what you want to see, so I'll leave it here.

There are many unclear points, and I didn't actually move them to check, so there may be some imperfections, but I think I have included the direction of the correction.I would appreciate it if you could use it as a reference.
