Set up your server

To integrate the PayPal iOS SDK, integrate both the client and the server with PayPal's Orders v2 API. Read this section to set up the server-side integration.

Know before you code

• Before you begin, create a server that communicates with your iOS app.
• Get your PayPal API credentials.

Step 1: Get a token

Get the OAuth 2.0 credentials, client_id and client_secret.

Get a server-side token

For server-side API calls, pass a server-side access token as the Authorization header. See Get started.

Get a client-side token

To authenticate the client SDK, provide a client-side token.

Pass your base64 encoded client_id in the Authorization header in a POST request to https://api-m.paypal.com/v1/oauth2/token.

Sample request

1curl -v -k https://api-m.paypal.com/v1/oauth2/token \
2
3-H "Authorization: Basic ${BASE_64_ENCODED_CLIENT_ID}" \
4-H "Content-Type: application/x-www-form-urlencoded" \
5-d "grant_type=client_credentials" \
6-d "response_type=id_token" \
7-d "target_customer_id=${CUSTOMER_ID}" \
8-d "entry_point=paypal_native_sdk"

target_customer_id is an optional parameter, which has your unique identifier for the customer.

Step result

A successful response returns the id_token value.

Sample response

1{
2    "scope": "SCOPE",
3    "id_token": "ID_TOKEN",
4    "token_type": "Bearer",
5    "app_id": "APP-ID",
6    "expires_in": 31945,
7    "nonce": "NONCE"
8}

Step 2: Get an order ID

An order represents a payment between two or more parties. Use the Orders v2 API to create an order and generate an order ID.
