Secure Token

Secure Token Errors

2. Set CREATESECURETOKEN to the value Y to request that the Gateway server return a token.

CREATESECURETOKEN=Y

3. Set SILENTTRAN to the value TRUE to suppress the display of hosted pages.

SILENTTRAN=TRUE

Transparent Redirect Example

The following is an example of an authorization parameter string that suppresses hosted pages.

TRXTYPE=A&BILLTOSTREET=123 Main St.&BILLTOZIP=95131&AMT=24.35&INVNUM=INV123

45&PONUM=PO12345&CURRENCY=USD&CREATESECURETOKEN=Y&SECURETOKENID=9a9ea8208de

1413abc3d60c86cb1f4c5&SILENTTRAN=TRUE

The Gateway server returns a SECURETOKEN and SECURETOKENID in the response. A tag

follows the SECURETOKEN to indicate the length of the token value returned.

RESULT=0&RESPMSG=Approved&SECURETOKEN[25]=Fj+1AFUWft0+I0CUFOKh5WA==&SECURET

OKENID=9a9ea8208de1413abc3d60c86cb1f4c5

When the customer enters their sensitive data into the credit card fields on your website and

clicks Submit, the browser posts the data to the Gateway server rather than to your website.

NOTE: It is highly recommended that you add scripting to ensure the the browser posts the

sensitive data directly to the PayPal Gateway server rather than to your website.

If you are using the PARMLIST parameter with the Transparent Redirect, see “Using the

PARMLIST Parameter” on page 44 for more information.

Secure Token Errors

A successful Payflow transaction will return RESULT=0 in the response. If your Secure Token

transaction is unsuccessful, you can pass the token 2 more times to Payflow before the token

expires.

A Payflow Secure Token will expire:

 If the same Secure Token is passed to Payflow a total of 3 times.

 20 minutes after the Secure Token was generated.

 When the token is used in a successful transaction.

If you receive one of the following error codes in the RESULT response parameter, then your

Secure Token has expired.
