Follow these steps to manually build the Log in with PayPal button:
Choose if you want to use the branded Log in with PayPal button or to create your own.
To create your own Log in with PayPal button, reference our Button design guide.
To use the branded Log in with PayPal button, use https://www.paypalobjects.com/devdoc/log-in-with-paypal-button.png for the button image location.
Note: To ensure the button image stays in sync with PayPal branding, don't download the button image and host it on your own server.
The authorization URL is called each time your users select the Log in with PayPal button. Construct the authorization endpoint according to the following template:
https://www.sandbox.paypal.com/signin/authorize?flowEntry=static&client_id=CLIENT-ID&scope=LIST-OF-SCOPES&redirect_uri=RETURN-URL| Variable | Description |
|---|---|
| client ID | Replace CLIENT-ID with your app's sandbox or live client ID.Example: ARfDleH_j-C17kxbdUzYivR70xP5Uy5N_DrFZVOvyZvNGBaPB_QNbwWkgF7lMsemGJycLRFVwaM |
| list of scopes | Replace LIST-OF-SCOPES with a space-separated list of scopes. You'll need to to include openid. See Scope attributes for details on how attributes map to scopes.Example: openid profile email address https://uri.paypal.com/services/paypalattributes |
| return URL | Replace RETURN-URL with the URL to return to after successful login. This URL must be encoded and match the Return URL set in Apps & Credentials in the Developer Dashboard.Example: https%3A%2F%2Fwww.myreturnurl.com&state=123456 |
https://www.sandbox.paypal.com/connect/?flowEntry=static&client_id=
