PayPal AMEX Support

PayPal now requires all merchants that would like to use AMEX in their PayPal account to sign an agreement directly with American Express.

Error Message

If you are getting the following error:

L_ERRORCODE1	10566
L_LONGMESSAGE1	The credit card type is not supported
L_SEVERITYCODE1	Error
L_SHORTMESSAGE1	Credit card type unsupported

this means that you have not accepted the PayPal AMEX agreement. Until you do this on your PayPal account it will not support American Express. You can read more about this at PayPal's AMEX Update.
