We use a flow for Oauth 2 authentication called Authorization Code. It basically consists of an exchange of an `authorization` token for an `access token`. For more detailed info, check out the [RFC spec here](http://tools.ietf.org/html/rfc6749#section-4.1)
|
||
|
|
||
|
The first step is to register your client app.
|
||
|
|
||
|
#### Registering the client
|
||
|
|
||
|
Set up a new client in `/oauth/applications/new`. For testing purposes, you should fill in the redirect URI field with `urn:ietf:wg:oauth:2.0:oob`. This will tell it to display the authorization code instead of redirecting to a client application (that you don't have now).
|
||
|
|
||
|
#### Requesting authorization
|
||
|
|
||
|
To request the authorization token, you should visit the `/oauth/authorize` endpoint. You can do that either by clicking in the link to the authorization page in the app details or by visiting manually the URL:
|
||
|
|
||
|
```
|
||
|
http://metamaps.cc/oauth/authorize?client_id=YOUR_CLIENT_ID&redirect_uri=urn:ietf:wg:oauth:2.0:oob&response_type=code
|
||
|
```
|
||
|
|
||
|
Once you are there, you should sign in and click on `Authorize`.
|
||
|
You will then see a response that contains your "authorization code", which you need to exchange for an access token.
|
||
|
|
||
|
#### Requesting the access token
|
||
|
|
||
|
To request the access token, you should use the returned code and exchange it for an access token. To do that you can use any HTTP client. Here's an example with `fetch`
|
||
|
|
||
|
```javascript
|
||
|
fetch('https://metamaps.cc/oauth/token?client_id=THE_ID&client_secret=THE_SECRET&code=RETURNED_CODE&grant_type=authorization_code&redirect_uri=urn:ietf:wg:oauth:2.0:oob', {
|
||
|
method: 'POST',
|
||
|
credentials: 'same-origin'
|
||
|
}).then(response => {
|
||
|
return response.json()
|
||
|
}).then(console.log).catch(console.error)
|
||
|
|
||
|
# The response will be like
|
||
|
{
|
||
|
"access_token": "de6780bc506a0446309bd9362820ba8aed28aa506c71eedbe1c5c4f9dd350e54",
|
||
|
"token_type": "bearer",
|
||
|
"expires_in": 7200,
|
||
|
"refresh_token": "8257e65c97202ed1726cf9571600918f3bffb2544b26e00a61df9897668c33a1"
|
||
|
}
|
||
|
```
|
||
|
|
||
|
You can now make requests to the API with the access token returned.
