Api key request denied

I am trying do that drawing path between two location,when I try do this I got a error this.
I shared below my url and error.I created Android api key,wht I got request denied error from google api
url: https://maps.googleapis.com/maps/api/directions/json?origin=41.050399,28.940599&destination=41.1119857,29.0186137&sensor=false&mode=driving&alternatives=true&key=AIzaSyB9LW3JNai1tGYtSVZrRGMGeJ71q7Y3DbA
json:{
"error_message" : "This IP, site or mobile application is not authorized to use this API key. Request received from IP address 78.186.62.169, with empty referer",
"routes" : [],
"status" : "REQUEST_DENIED"
}

I dont think that is the correct way of using it, try something like this
https://maps.googleapis.com/maps/api/js?key=<YOUR_API_KEY>&callback=initMap
and if it is in a variable then u will need " " like
src="https://maps.googleapis.com/maps/api/js?key=<YOUR_API_KEY>&callback=initMap"

Directions API web service requires a Server API key, not Android API key.
Please look at the documentation:
https://developers.google.com/maps/documentation/directions/get-api-key#get-an-api-key

Getting : ipRefererBlocked on android app

I'm trying to use the "Google Identity Toolkit" with the "tutorial" android demo app, but now I get this error:
{
"error": {
"errors": [
{
"domain": "usageLimits",
"reason": "ipRefererBlocked",
"message": "There is a per-IP or per-Referer restriction configured on your API key and the request does not match these restrictions. Please use the Google Developers Console to update your API key configuration if request from this IP or referer should be allowed.",
"extendedHelp": "https://console.developers.google.com"
}
],
"code": 403,
"message": "There is a per-IP or per-Referer restriction configured on your API key and the request does not match these restrictions. Please use the Google Developers Console to update your API key configuration if request from this IP or referer should be allowed."
}
}
Any Idea? In the Google console I need allow some thing? Where?
OAuth 2.0 client IDs:
Android,
Web application
And on Identity Toolkit API console, it allow I select "Web application" client ID in Google provider.
And I have set up this in my "tutorial" app

This error is usually caused when you are trying to run the code on a URL you didn't add to the referrer URLs in the console.
To fix this go to the Google Developer Console, then under API Manager click credentials and find your browser key. On this page you can add any URLs that will be using that key.
Remember it treats www. differently, so to cover all possible pages you could do this:
.domain.com/
domain.com/*

I figured out today that there is a bug when you create a new Android API key. You will have probably noticed that there was also a Browser API key that was generated when you created the Android API key. My Browser API key had no name, and was therefore not configurable. However, I performed a bit of URL manipulation magic to be able to access and edit my Browser API key. Here's what I did:
1) Click on the name of the Android API key
2) Edit the URL right before the ? such that the number before the ? matches the (0-based) index of the position of your Browser API key. That is, if your browser api key appears second in your list of two API keys, then your Android API key would have been first, at position 0. Therefore the URL would read something like this:
.../key/0?...
So now you want to change it to look like this:
.../key/1?...
3) From here you should be able to change your allowed referrers to
http://yourdomain.com/*
Then, so long as you have your keys set up properly everything should work as expected! Also, note that after you do this once you will then have a name for your browser key, and it will be easily editable in the future!
Best of luck!

You will need to...
Create an Android API Key
Set the package name and SHA-1 of your signing key file(see gitkit guide on how to do that)
Use that API Key for the identitytoolkit.api_key value

Place API for Android

I'm trying to use the Google Places API in my application. For that I need to generate Server Key.
I used my device IP address to generate a Server Key. My app works only in my device. If I use some other device I get an error:
{
"error_message" : "This IP, site or mobile application is not authorized to use this API key.",
"predictions" : [],
"status" : "REQUEST_DENIED"
}
Could you please help me in this regards. How to generate Server key which works for all devices.

Try to create a new Places API key. When creating the key choose the server but leave the IP field blank (so as to allow any IP address).
Notify and vote up if it works.

Google places autocomplete api - REQUEST_DENIED

I'm creating app that use autocomplete places google api.
And I don't know what is wrong but all the time I got responses like:
{
"predictions" : [],
"status" : "REQUEST_DENIED"
}
I send req : https://maps.googleapis.com/maps/api/place/autocomplete/json?input=Paris&types=geocode&language=fr&sensor=true&key=mykey
Documentation says :
REQUEST_DENIED indicates that your request was denied, generally because of lack of a sensor parameter.
I have sensor parameter, maybe it is something with api key.
Is there any page where can I get google's log :), to see why I got REQUEST_DENIED?
I use api key from :
http://code.google.com/intl/pl-PL/android/maps-api-signup.html
Maybe I have to get an api key from somewhere else.

You should be able to view your API Key by going to the API Console first:
https://code.google.com/apis/console
If you haven't yet, you will need to create a new "Project" and then enable the Predictions services first by using the On/Off switch.
Please post your results, I have a similar problem with getting the REQUEST_DENIED response, but I've already got the API key and I'm using the sensor parameter like their documentation states.
It is frustrating that Google doesn't give any sort of response code along with REQUEST_DENIED so you can see why it's denying it. This will be difficult to support and troubleshoot in a production environment if this randomly goes out without providing any details as to why.
Update:
I just found this works for me now, but only after changing my requests to GET requests instead of POST. For reasons unknown, Google returns REQUEST_DENIED for POST requests but allows the same request via GET. A quick test for you to see if this is your problem would be to put the URL together with your API key and other parameters and try it through your browser instead. If that works then just rewrite your Android code to use GET instead of POST and you should be all set.

It was solved for me when I exchanged the API key. I was using the one under Android device, I changed it to the one "Key for browser apps (with referers)" and it worked for me although I'm using Android Device.

I recommend using .getJson() to get an error message along with your response to know what is exactly wrong.
For my case in flutter: I used googlePlace!.autocomplete.getJson(value);
and i got the following response.
{ "error_message" : "You must enable Billing on the Google Cloud Project at https://console.cloud.google.com/project/_/billing/enable Learn more at https://developers.google.com/maps/gmp-get-started", "predictions" : [], "status" : "REQUEST_DENIED" }

That's the wrong API key. Follow the steps here to get the right one.

Make sure you API keys are generated correctly and that you have enabled the necessary APIS.
In my case, when designing iOS application - I need to enable Google Maps SDK for iOS, Google Places API for iOS
And most importantly, and without being mentioned by Google (in any other place as well) enable Google Places API Web Service.
With this, I ended a 2 day search for my pesky problem.
And, of course, make sure you use Key for server applications
