PayPal responds with a request token that you use in following steps to obtain an access

token.

NOTE: The request token from this step is different than the access token, which you use

to access permissions that already have been granted.

2. Redirect the account holder’s browser to PayPal and include the request token in the

request_token parameter.

https://www.paypal.com/cgi-bin/webscr?

cmd=_grant-permission&request_token=token

PayPal initiates granting permissions. When the account holder grants permissions, PayPal

returns a verification code, which you use in the next step.

NOTE: The verification code expires in about 15 minutes.

3. Set up your request and call the GetAccessToken API operation.

– Specify the request token in the token field.

– Specify the verification code in the verifier field.

– Send the request to

https://svcs.paypal.com/Permissions/GetAccessToken.
