Where can I get Google developer key - google-api

Question

I am working on Google API like chat, contacts and so on...
I am stuck on developer_key as mentioned in gdata doc.
You can get this at https://code.google.com/apis/console:
'developer_key' => ''
I have already:
// OAuth2 Settings, you can get these keys at https://code.google.com/apis/console
'oauth2_client_id' => '',
'oauth2_client_secret' => '',
'oauth2_redirect_uri' => ''
Where can I find developer key?
I found some thing like this
http://code.google.com/apis/youtube/dashboard/gwt/index.html
But I understand this to be only for youtube.

Answer 1

It's the API key as listed under 'API Access', the 'Simple API Access' box.

Answer 2

First activate Google+ API, then you will get "Simple API access" box, from there you can get
developer key as API key
https://code.google.com/apis/console/?api=plus
or read this: http://code.google.com/p/google-api-php-client/wiki/OAuth2

Update Nov 2015:
Sometime in late 2015, the Google Developers Console interface was overhauled again. For the new interface:
Select your project from the toolbar.
Open the "Gallery" using hamburger menu icon on the left side of the toolbar and select 'API Manager'.
Click 'Credentials' in the left-hand navigation.
Alternatively, you can click 'Switch to old console' under the the three-dot menu (right side of the toolbar), then follow the instructions below.
For the NEW (edit: OLD) Google Developers Console:
You get your 'Developer key' (a.k.a. API key) on the same screen where you get your client ID/secret. (This is the 'Credentials' screen, which can be found under 'APIs & auth' in the left nav.)
Below your client ID keys, there is a section titled 'Public API access'. If there are no keys in this this section, click 'Create new Key'. Your developer key is the 'API key' specified here.

Update no 3:
You can get a Developer_Key from here Get your Google Developer Key
Check this tutorial
{select as answered, if it answered.}
Update no 2:
"API key" is the DEVELOPER_KEY
if you check this code reference,
it states
Set DEVELOPER_KEY to the "API key" value from the "Access" tab of the Google APIs Console http://code.google.com/apis/console#access`
Wiki on step by step to get API Key & secret
Update:
Developer API Key! probably this is what you might be looking for
http://code.garyjones.co.uk/google-developer-api-key
OR
If say, for instance, you have a web app which would require a API key then check this:
Go to Google API Console Select you project OR Create your project.
Select APIs & Auths
API Project from the Dropdown on the left navigation panel
API Access
Click on Create another Client ID
Select Service application refer it here
The Service application that you have created can be used by your Web apps such as PHP, Python, ..., etc.

Answer 5

2017 Update
Open Google API - https://console.developers.google.com
Go to Credentials.
Click on the 'Create Credentials' button. At time of writing it's currently a blue coloured dropdown.
Select API Key.
You should get a dialog from where you can copy this API key to use in your project. Hope this helps.

Answer 6

In the old console layout :
Select your project
Select menu item "API access"
Go to the section below "Create another client ID", called "Simple API Access"
Choose one of the following options, depending on what kind of app you're creating (server side languages should use the first option - JS should use the second) :
Key for server apps (with IP locking)
Key for browser apps (with referers)
In the new cloud console layout :
Select your project
Choose menu item "APIs & auth"
Choose menu item "Registered app"
Register an app of type "web application"
Choose one of the following options, depending on what kind of app you're creating (server side languages should use the first option - JS should use the second) :
Key for server apps (with IP locking)
Key for browser apps (with referers)
In case of both procedures, you find your client ID and client secret at the same page. If you're using a different client ID and client secret, replace it with the ones you find here.
During my first experiments today, I've succesfully used the "Key for server apps" as a developer key for connecting with the "contacts", "userinfo" and "analytics" API. I did this using the PHP client.
Wading through the Google API docs certainly is a pain in the #$$... I hope this info will be useful to anyone.

Answer 7

Please use Google API console
Create a new project
For the created project goto API access
There you will find your Client ID and Secret.
And the API key in the last is your developer key.

Answer 8

Recent Update July 2017:
Go to Google Console
Click on Left most top panel and click credentials.
In the API keys table, you will find the API key in the key column.

Answer 9

API Key is your developer key.
Hit https://www.googleapis.com/webfonts/v1/webfonts?key= in your browser by enabling web fonts api and you will see result.
Refer this blog http://code.garyjones.co.uk/google-developer-api-key/ for more information

Answer 10

I explored the google docs and found that developer key and api is same thing.

Answer 11

in https://code.google.com/apis/console/ , in SERVICES, turn on YOUTUBE API, then click API ACCESS in the left menu.

Answer 12

"Public API access" the key generated there is the key you got to paste into your public static final String DEVELOPER_KEY as part of this writing 26.12.2013
It is not the clientID but you got take the steps mentioned above to obtain one and generate the public api access key.

Answer 13

Go to https://code.google.com/p/google-api-php-client/wiki/OAuth2
Scroll down to where it says 'Visit the Google API Console to generate your developer key, OAuth2 client id, OAuth2 client secret, and register your OAuth2 redirect uri. Copy their values since your will need to input them in your application.'
Click on the 'Google API Console' link.
When it pops up and says 'Welcome to the new Google Developers Console! Prefer the old console? Go back | Dismiss' Click on 'GO BACK'

Answer 14

If you are only calling APIs that do not require user data, such as
the Google Custom Search API, then API keys might be simpler to use
than OAuth 2.0 access tokens. However, if your application already
uses an OAuth 2.0 access token, then there is no need to generate an
API key as well. Google ignores passed API keys if a passed OAuth 2.0
access token is already associated with the corresponding project.
Note: You must use either an OAuth 2.0 access token or an API key for
all requests to Google APIs represented in the Google Developers
Console. Not all APIs require authorized calls. To learn whether
authorization is required for a specific call, see your API
documentation.

Answer 15

tl;dr
Developer Key = Api Key (any of yours)
find it in Google Console -> Google API -> Credentials

Answer 16

You should be able to generate a Youtube API key there.
The recommended way to authorize your API call is to use OAuth 2.0 (without API key), as pointed by the documentation an API key is only necessary when using OAuth 1.0 credentials.
The API key for your application can be found in the Google APIs Console in API Access > Simple API.
