Using CloudFlare API via PHP/Curl returning error

Question

I am working on updating my DNS via a PHP script. I've looked at the API documentation relating to cURL so I am trying to convert the cURL post to be PHP.

I have the following code:

$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "https://api.cloudflare.com/client/v4/zones/<MY_ZONE>/dns_records/<MY_ID>"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_VERBOSE, 1); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); $fields = array(); $fields["X-Auth-Email"] = "[email protected]"; $fields["X-Auth-Key"] = "MY_KEY"; $fields["Content-Type"] = "application/json"; curl_setopt($ch, CURLOPT_HTTPHEADER, $fields); $dnsData = array(); $dnsData["id"] = "MY_ID"; $dnsData["type"] = "A"; $dnsData["name"] = "home"; $dnsData["content"] = $newIPAddress; curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($dnsData)); echo "posting to API<br />"; $result = curl_exec($ch); echo "Result: " . $result;

With the above code I am getting the following response back from Cloudflare.

{"success":false,"errors":[{"code":6003,"message":"Invalid request headers","error_chain":[{"code":6100,"message":"Missing X-Auth-Email header"},{"code":6101,"message":"Missing X-Auth-Key header"},{"code":6105,"message":"Invalid Content-Type header, valid values are application/json,multipart/form-data"}]}],"messages":[],"result":null}

I've tried changing the json_encode to http_build_query instead but both return the same error.

i think you are misusing curl_setopt.

This is the correct way to do set multiple header:

curl_setopt($ch,CURLOPT_HTTPHEADER, ['HeaderName: HeaderValue','HeaderName2: HeaderValue2']);

EDIT

To make it more clear:

$headers = [ 'X-Auth-Email: [email protected]', 'X-Auth-Key: MY_KEY', 'Content-Type: application/json' ]; curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

Headers are not key/value pair, but rather only values.

Also, you should send POST data with http_build_query().

The issue is that you're telling it to use application/json when you're passing it form data. Set your Content-type to multipart/form-data and it should work. If you want an example of how to use the JSON API, let me know.

EDIT: CURLOPT_HTTPHEADER does not accept key/values, only values. More information

$fields["X-Auth-Email"] = "[email protected]"; would therefore need to be changed to: $fields[]= "X-Auth-Email: [email protected]";

I have tested this code and i think you can use it without any problem. example:

 $request_headers = array( 'X-Auth-Email: [email protected]', 'X-Auth-Key: d820fa8fc881921323e08a2c19b8347896ac26', 'Content-Type: application/json' );

then:

curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers);
