We have developed our own store using the PBA-S API XML commands. We have based our store on the PBA-S store. Before our update to 4.3.3-47 we would pass on the array for ssl_hash the item ssl_csr to both calculate_order and place_order.
But the same commands do not work with PBA-S 4.3.3.
The param name has changed from ssl_csr to ssl_csr_csr.
The param name was changed from ssl_csr to ssl_csr_csr.
The array that is passed in the $order_data array, param 'ssl_hash' in includes/hspc_functions.php. Those values are stored in $_SESSION['ssl']:
Array( 'action' => 'continue', 'ssl_csr_type' => 'csr_type_file', 'ssl_csr_csr' => 'CSR CODE', (...) );
In future it's planed to describe API changes in release notes. Bug is PBAS-28834.
