Follow these steps to manually build the Log in with PayPal button:

1. Select button type

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.

2. Construct authorization endpoint

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:

1https://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`

Sample URL

1https://www.sandbox.paypal.com/connect/?flowEntry=static&client_id= ARfDleH_j-C17kxbdUzYivR70xP5Uy5N_DvNGBaPB_QNbwWkgF7lMsemGJycLRFVwaM&response_type=code&scope=openid profile email address&redirect_uri=https://www.myreturnurl.com&state=123456

3. Customize functionality

You can optionally use the following advanced parameters to customize your button:

Parameter	Description
`response_type`	`code` – to receive authentication code in the response. `id_token` – used only by direct instruction of your integration team.
`fullPage`	To open the flow in a mini browser, do not pass this parameter. To open the Log in with PayPal flow as a full page in the same tab, pass `true`.

4. Get authorization code

When your users successfully log in to PayPal and consent to sharing their basic information, PayPal passes an authorization code to the return URL you specify.

Parameter	Description
authorization code	The authorization code is appended as a parameter to the return URL after the user logs in and consents to share information with your website.

Sample URL

1https://myreturnurl.com/?code={authorization_code}&scope=address openid profile email
