php - sending Paypal payment call returning 400 malformed request error -


i trying create paypal payment using php. keep getting 400 malformed request error. believe problem following string:

$postdata =' {     "intent": "sale"     "redirect_urls": {         "return_url": ' . $url_success .',         "cancel_url": ' . $url_cancel .'     },     "payer": {         "payment_method": "paypal"     },     "transactions": [         {             "amount": {                 "total": "' . $saletotal .'",                 "currency": "usd"             },             "description": "test payment."         }     ] } ';

i sending string using curl in following line

curl_setopt($ch, curlopt_postfields, $postdata);

here string printed out:

{ "intent": "sale" "redirect_urls": { "return_url":  "http://localhost/~user/test/controller/paypaltestview.php", "cancel_url":  "http://localhost/~user/test/controller/canceltestview.php" }, "payer": {  "payment_method": "paypal" }, "transactions": [ { "amount": { "total": "8.31782",  "currency": "usd" }, "description": "test payment." } ] }

here response get:

{"name":"malformed_request","message":"the request json not  formed.","information_link": "https://developer.paypal.com/webapps/developer/docs/api/#malformed_request", "debug_id":"7d56ae815e584"}

i'm pretty sure problem in $postdata, although have no idea what's wrong. tried following example: paypal rest api bad request, still isn't working. problem similar example in sending , receiving authentication token successfully. problem when trying send payment api call. see i'm doing wrong? thank you!

i got same problem before. did put data first in array:

$data = array(  "intent"=>"sale",              "redirect_urls"=>array(                 "return_url"=>"<return site>",                  "cancel_url"=>"<cancel site>"             ),             "payer"=>array(                 "payment_method"=>"paypal"             ),             "transactions"=>array(                 array(                     "amount"=>array(                         "total"=>"7.47",                         "currency"=>"usd"                     ),                     "description"=>"this payment transaction description."                 )             )         );

and http header:

$header = array( "content-type:application/json", "authorization:bearer <token here>"

);

then on postfield, encode data using json_encode:

curl_setopt($ch, curlopt_postfields, json_encode($data));

i hope help.
