Token requests

Authorization codes are one-use tokens. When used to retrieve an access_token they return a refresh_token that may be used to retrieve the next access_token. The following section takes you through retrieving your first refresh_token.

Initial request

The first time you request a token, you'll need the following:

Application's security profile client_id
Application's security profile client_secret
Application's registered redirect_uri
Application authorization code previously created
The grant_type to use, which should be authorization_code

Enter the client_id, client_secret, authorization_code, and grant_type as URL encoded form data.
Make an HTTP request.

Curl command to generate tokens from authorization_code:


    curl --request POST \
    --url https://api.amazon.com/auth/o2/token \
    --header 'content-type: application/x-www-form-urlencoded' \
    --data 'grant_type=authorization_code' \
    --data 'code=ANxuOkcwmzUHvimjMTAX'
    --data 'client_id=amzn1.application-oa2-client.20534a91be57487e9c3547dada8a7394' \
    --data 'client_secret=c007c411c9657dde807a11a96a3cfd8a2972f9599ac28de241675832f63cac05' \
    --data 'redirect_uri=https://development.amazon.com/ap/ibatest'

Two tokens are returned.

access_token
This short-lived token is included in HTTP requests to the API. Although short-lived, it's sensitive, so don't share it. New access_tokens can easily be generated.
refresh_token
This indefinite token is used by the client to request all subsequent tokens and is also sensitive. Combined with the client_id and client_secret for your application, more access_tokens can be created. Note: The OAuth2 spec allows the refresh_token to change each time it's used. While the Amazon implementation doesn’t always do so, you should assume that it could happen any time and use a mutable secrets store for this value.

Ordinary token requests

Each subsequent call to get a new short-lived token must use a grant_type of refresh_token and include the refresh_token. The steps below are what your application will request each time it begins a new session. This step uses the refresh_token combined with the existing secrets to issue a new access_token which are short-lived.

Enter the client_id, client_secret, redirect_url, and authorization_code, and grant_type as URL encoded form data.
Make an HTTP request (using either Curl or Reference Implementation application).

Use the following Curl command to generate access tokens using a refresh token:


    curl --request POST \
    --url https://api.amazon.com/auth/o2/token \
    --header 'content-type: application/x-www-form-urlencoded' \
    --data 'grant_type=refresh_token' \
