I am having difficulties with PayPal payments.
- Logged inn Sandbox (paypal)
- Created a seller account and several buyer accounts
- Used seller account and https://www.sandbox.paypal.com/cgi-bin/webscr
at the OCS.
It looks as if payments are done, a transaction id is given in the paypal, however there is no transaction in the paypal_transactions table. In the buyer account at PayPal, all the transactions get "unclaimed" status and it is not possible to update their status; there are no transactions at the seller account either.
What should I do to let it work properly?
