Laravel: How can we know the error when sending HTTP request - php

Question

I am trying to use a Http method to reactivate user's subscription, using HTTP request, but there might be two problems that exist (the json code would return two potential errors):
Reactivating a canceled subscription with an invalid payment profile
Given you have a canceled subscription with ID "1000"
The subscription has an invalid payment profile
Send a PUT request to https://sample.chargify.com/subscriptions/1000/reactivate.json
The response status should be "422 Unprocessable Entity"
The subscription should be canceled with the following response
{
"errors": ["The credit card on file could not be charged."]
}
Attempting to reactivate an already active subscription
Given you have an active subscription with ID "1000"
Send a PUT request to https://sample.chargify.com/subscriptions/1000/reactivate.json
The response status should be "422 Unprocessable Entity"
The subscription should be active with the following JSON response
{
"errors": ["Cannot reactivate a subscription that is not marked
\"Canceled\", \"Unpaid\", or \"Trial Ended\"."]
}
I am new to Laravel, therefore I would like to know the way I can detect the error when sending the request to the server, but right now I only have one option (without a valid if statement) which cannot detect the problem.
I think an if statement would do but I'm not sure how. Thanks!

Okay so the if statement will work if:
if (isset(response()->error)){
// error message
} else {
// success message
}
