I am trying to use PHP cURL to retrieve some data from SurveyMonkey's API and I keep getting a 500 error.
Here is my code:
$requestHeaders = array(
'Content-Type: application/json',
'Authorization: Bearer ' . $accessToken,
);
$baseUrl = 'https://api.surveymonkey.net';
$endpoint = '/v2/surveys/get_survey_list?api_key=XXXXXXXXXXXXXX';
$fields = array(
'fields' => array(
'title','analysis_url','date_created','date_modified'
)
);
$fieldsString = json_encode($fields);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $baseUrl . $endpoint);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $requestHeaders);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fieldsString);
$result = curl_exec($ch);
curl_close($ch);
The response I get is
{
"status": 500,
"request_id": "e0c10adf-ae8f-467d-83af-151e8e229618",
"error": {
"message": "Server busy, please try again later."
}
}
This works perfectly on the command line:
curl -H 'Authorization:bearer XXXXX'
-H 'Content-Type: application/json' https://api.surveymonkey.net/v2/surveys/get_survey_list/?api_key=XXXXXXXX
--data-binary '{"fields":["title","analysis_url","date_created","date_modified"]}'
Thanks!
You were close, but there are a couple small mistakes.
First, while you do specify the Content-Type
correctly ( application/json
), you have not specified the Content-Length
.
Make this change to $requestHeaders
and move it below the creation of $fieldsString
:
$requestHeaders = array(
'Content-Type: application/json',
'Authorization: Bearer ' . $_GET['code'],
'Content-Length: ' . strlen($fieldsString)
);
Second, you have set CURLOPT_POST
to true. This will force CURL to treat your request as a form POST which has a content-type of application/x-www-form-urlencoded
. This will create a problem because SurveyMonkey is expecting the content-type application/json
.
Remove this:
curl_setopt($ch, CURLOPT_POST, true);
and replace it with this:
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
