Login with Zip

Give your shoppers the option to Login to your website using Zip and pay seamlessly.

The API call you will initially make to obtain a user access_token and refresh_token is the /tokens endpoint.

This request is made once you have received a customer authority code back from Zip and will contain:

  • Customer auth code
  • client_id
  • client_secret
  • code_verifier

The Zip API response will contain:

  • access_token (for placing charges and sending back to the client side)
  • refresh_token (for permanent storage)

This /tokens API call should be made from your server and not directly from the client front end.

The API request

Customer authorisation code

You will obtain the customer auth code when it is returned by Zip to your server side endpoint (the redirectUri you defined in your initial auth request to Zip). This will occur after the customer has logged in and approved.

Zip will redirect in the below format and the auth code is labelled 'code':

https://myserverside.com/zip?code=77b2102aea1a3d463c345ea493c628c346461cbb13eb7f91d1e8fd6ae8f2e5eb&scope=openid%20profile%20read_balances%20create_charges%20offline_access&state=jfvJBv2EV9ZA&session_state=GmtRKUaELHXGNycpcdBUEbk1na7eFlrsT0xHI_OJ8og.52a40c767fb730bfeb311f9053be8124

Code verifier

This should match what was passed to Zip in your initial Auth request.

Client ID and Client secret

These will be provided by the Zip team for each environment.

Redirect Uri

This should be the same server side endpoint used in your JS config and that you passed in your auth request.

The full request

curl --location --request POST 'https://sandbox.zip.co/login/connect/token' \
--header 'Content-Type: application/x-form-www-urlencoded' \
--form 'client_id="<client_id>"' \
--form 'grant_type="authorization_code"' \
--form 'code_verifier="<code_verifier>"' \
--form 'code="<authorization_code>"' \
--form 'redirect_uri="<redirect_uri>"' \
--form 'client_secret="<client_secret>"'

Passing the access_token to the front end

For the Zip account and payment_option widgets to load customer account info, and for customer data to be available in the front end, we must pass the access_token back to the client front end. There are 2 suggested ways of doing this that our widgets support:

  1. Put the access_token in a cookie
zip.auth.init({
      accessTokenCookieKey: 'zip-auth-access-token',
})
  1. Pass the access_token in a script
zip.auth.init({
      accessToken: 'accessToken',
})
