I am using an unrestricted api key for Google Maps SDK for iOS with my iOS Xcode project after having created a new key and deleting the old key

Question

I am using an unrestricted api key for Google Maps SDK for iOS with my iOS Xcode project after having created a new key and deleting the old key, but my request is denied. It worked before when I used the first key.

Here is the error message:

[error_message: This API project is not authorized to use this API., status: REQUEST_DENIED, routes: <__NSArrayM 0x60000097f5d0>(

)

Here is my code in AppDelegate:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    
    GMSServices.provideAPIKey("***")
    GMSPlacesClient.provideAPIKey("***")

}

Here is my code where I run the request:

let directionsURLString = "https://maps.googleapis.com/maps/api/directions/json?origin=1%20Cuntry%20Club%20Ln,%20Texarkana,%20AR&destination=1%20Cuntry%20Club%20Ln,%20Texarkana,%20AR&waypoints=optimize:true%7C921%20Orleans%20St,%20Texarkana,%20AR%7C2510%20E.%2011th%20St.,%20Texarkana,%20AR%2071846%7C4125%20Lynn%20Dr,%20Texarkana,%20TX%7C6002%20Yorktown%20Pl,%20Texarkana,%20TX%7C7007%20Stonewall%20Dr,%20Texarkana,%20TX%7C4009%20Constitution%20Dr,%20Texarkana,%20TX%7C413%20Dundee%20Rd,%20Texarkana,%20AR%7C2219%20Hazel%20St,%20Texarkana,%20TX%7C414%20Central%20Ave,%20Wake%20Village,%20TX&mode=driving&key=***"

let directionsURL = URL(string: directionsURLString)!

DispatchQueue.main.async {
    
    do {
        
        let directionsData = try Data(contentsOf: directionsURL)
        
        let dictionary: Dictionary<NSObject, AnyObject> = try JSONSerialization.jsonObject(with: directionsData, options: JSONSerialization.ReadingOptions.mutableContainers) as! Dictionary<NSObject, AnyObject>
        
        print(dictionary)
        
        let status = dictionary["status" as NSObject] as! String
        
        print("status=" + status)
        
    } catch {
        
        print(error)
        
    }
    
}

Answer 1

If your API key is indeed completely unrestricted, then this REQUEST_DENIED error you're getting can mean the following:

A) There's an issue with the billing account linked to your project, or you have not created one. Please double check your billing account is enabled and in good standing.

B) The Directions API is disabled on your project. To enable it please check out this guide.

Hope this helps!
