Generate PayPal-Auth-Assertion header

Pass the PayPal-Auth-Assertion header with the standard Content-Type, Authorization, and PayPal-Request-IDheaders. The value of the PayPal-Auth-Assertion header can be generated as follows:

1// client-side JavaScript
2
3function encodeObjectToBase64(object) {
4  const objectString = JSON.stringify(object);
5  return window.btoa(objectString);
6}
7
8const clientId = "CLIENT-ID";
9const sellerPayerId = "SELLER-PAYER-ID"; // preferred
10// const sellerEmail = "SELLER-ACCOUNT-EMAIL"; // use instead of payer-id if required
11
12const header = {
13  alg: "none"
14};
15const encodedHeader = encodeObjectToBase64(header);
16
17const payload = {
18  iss: clientId,
19  payer_id: sellerPayerId
20  // email: sellerEmail
21};
22const encodedPayload = encodeObjectToBase64(payload);
23
24const jwt =\`${encodedHeader}.${encodedPayload}.\`; // json web token
25console.log(\`Paypal-Auth-Assertion=${jwt}\`);

Note: The token contains two period (.) characters, which are required according to the JSON web token structure.

Modify the code

Use the client ID of the platform or marketplace from the PayPal Developer dashboard for clientID.

The sellerPayerId is the payer ID of the receiving seller's PayPal account. You can also use email instead of payer_idand supply the email address of the seller's PayPal account.

Example functions to generate the PayPal-Auth-Assertion header in other programming environments:

Node.js

1// Node.js
2
3function encodeObjectToBase64(object) {
4  const objectString = JSON.stringify(object);
5  return Buffer
6    .from(objectString)
7    .toString("base64");
8}
9
10const clientId = "CLIENT-ID";
11const sellerPayerId = "SELLER-PAYER-ID"; // preferred
12// const sellerEmail = "SELLER-ACCOUNT-EMAIL"; // use instead if payer-id unknown\n
13const header = {
14  alg: "none"
15};
16const encodedHeader = encodeObjectToBase64(header);
17
18const payload = {
19  iss: clientId,
20  payer_id: sellerPayerId
21  // email: sellerEmail
22};
23const encodedPayload = encodeObjectToBase64(payload);
24
25const jwt = \`${encodedHeader}.${encodedPayload}.\`; // json web token
26console.log(\`Paypal-Auth-Assertion=${jwt}\`);

14    // "{\"iss\":\"" + clientId + "\",\"email\":\"" + sellerEmail + "\"}";\n
15    byte[] encodedHeader = Base64.encodeBase64(header.getBytes());
16    byte[] encodedPayload = Base64.encodeBase64(payload.getBytes());\n
17    String jwt = new String(encodedHeader) +
18      "." +
19      new String(encodedPayload) +

Create product

To create a product for your subscription plan, copy and modify the following code:

Sample request

API endpoint used: Create product

1curl -v -X POST https://api-m.sandbox.paypal.com/v1/catalogs/products -H "Content-Type: application/json" -H "Authorization: Bearer ACCESS-TOKEN" -H "PayPal-Request-Id: REQUEST-ID" -H "PayPal-Auth-Assertion: AUTH-ASSERTION" -d '{
2      "name": "Video Streaming Service",
3      "description": "A video streaming service",
4      "type": "SERVICE",
5      "category": "SOFTWARE",
6      "image_url": "https://example.com/streaming.jpg",
7      "home_url": "https://example.com/home"
8    }'

Modify the code

After you copy the code in the sample request, modify the following:

Change ACCESS-TOKEN to your access token.

Replace REQUEST-ID with a unique ID that you generate. This ID helps prevent duplicate requests if the API call is disrupted.

Change the AUTH-ASSERTION header to your JSON Web Token (JWT) assertion that identifies your seller. For more information on how to create a JWT, see PayPal-Auth-Assertion.

Optional: Change parameters such as the name and description to represent your product.

Step result

A successful request results in the following:

The HTTP status code 201 Created.

A JSON response body that contains an id for the product. Use this ID to complete other actions through the REST API, such as creating a subscription plan.

47    }'

Modify the code

After you copy the code in the sample request, modify the following:

Change Access-Token to your access token.

Replace the value for the PayPal-Partner-Attribution-Id to your BN code.

Replace the sample ID for PayPal-Request-Id with a unique ID you generate. This ID helps prevent creating duplicate products in the event that the API call is disrupted. See also: API Idempotency.

Replace the PayPal-Auth-Assertion header with your own JSON Web Token (JWT) assertion that identifies your seller. For more information on how to create a JWT, see PayPal-Auth-Assertion.

Determine the value for subscriber/shipping_address:
- If you don't need to ship your services, set application_context/shipping_preference to NO_SHIPPING. This hides shipping information fields on the PayPal Review page.
- If the buyer entered a shipping address on the seller's site, pass the shipping address to PayPal here.
- If the buyer didn't enter a shipping address on the seller's site, you can edit the shipping address on the PayPal Review page. Leave application_context/shipping preference blank or set it to GET_FROM_FILE.

(Optional) Use the application_context/user_action field to automatically activate subscriptions. Set the field to SUBSCRIBE_NOW or send it empty. The default value is SUBSCRIBE_NOW. Otherwise, you need to make a POST v1/billing/subscriptions/{ID}/activate call to activate the subscription.
