-The PayPal SDK uses access tokens for authentication.

-> The following example can be adapted to any server-side language/framework of your choice. We use command-line curl requests to demonstrate the overall composition of the Access Token HTTP request.

-To create an access token:
-
-1. Follow the steps in [Get Started](https://developer.paypal.com/api/rest/#link-getstarted) to obtain a client ID and secret from the PayPal Developer site.
-1. Make an HTTP request with Basic Authentication using client ID and secret to fetch an access token:
-
-**Request**
-```bash
-# for LIVE environment
-curl -X POST https://api.paypal.com/v1/oauth2/token \
--u $CLIENT_ID:$CLIENT_SECRET \
--H 'Content-Type: application/x-www-form-urlencoded' \
--d 'grant_type=client_credentials&response_type=token&return_authn_schemes=true'
-
-# for SANDBOX environment
-curl -X POST https://api.sandbox.paypal.com/v1/oauth2/token \
--u $CLIENT_ID:$CLIENT_SECRET \
--H 'Content-Type: application/x-www-form-urlencoded' \
--d 'grant_type=client_credentials&response_type=token&return_authn_schemes=true'

-:warning: Make sure the environment variables for `CLIENT_ID` and `CLIENT_SECRET` are set.

-  "token_type": "Bearer",
-  "app_id": "...",
-  "expires_in": 32400,

-Use the value for `access_token` in the response to create an instance of `CoreConfig` to use with any of the SDK's feature clients.

 ## Testing
 
 This project uses the `XCTest` framework provided by Xcode. Every code path should be unit tested. Unit tests should make up most of the test coverage, with integration, and then UI tests following.
