where to add API Key to the Curl in php - php

Question

Am trying to leverage the Anvil API for PDF.
Here is their sample request.
curl \
-X POST \
-u YOUR_API_KEY: \
-H 'Content-Type: application/json' \
-d '{ "data": { "someKey": "some data" } }' \
https://app.useanvil.com/api/v1/fill/{pdfTemplateID}.pdf > test.pdf
My problem is where to add the API KEY. I have tried adding it to the header but it throws error {"name":"AuthorizationError","message":"Not logged in."}
Here is the coding so far
$url2="https://app.useanvil.com/api/v1/fill/first.pdf";
$ch2 = curl_init();
curl_setopt($ch2,CURLOPT_URL, $url2);
$apiKey ='my api key goes here';
$post_data ='
{
"data": {
"someName": "Bobby",
"someDate": "2018-10-31",
"anAddress": {
"street1": "123 Main St",
"city": "San Francisco",
"state": "CA",
"zip": "94106"
}
}
}';
curl_setopt($ch2, CURLOPT_HTTPHEADER, array(
//'Content-Type:application/json'
'Authorization: ' . $apiKey
));
curl_setopt($ch2,CURLOPT_CUSTOMREQUEST,'POST');
curl_setopt($ch2,CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch2,CURLOPT_SSL_VERIFYPEER,0);
curl_setopt($ch2,CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($ch2,CURLOPT_RETURNTRANSFER, true);
echo $response2 = curl_exec($ch2);
curl_close($ch2);

Answer 1

The curl command you provided has option -u, which is expecting data as username:password ,from curl man
-u/--user user:password Specify user and password to use for server authentication. If this option is used several times, the last one
will be used.
which in PHP you have to send headers like below snippet:
CURLOPT_HTTPHEADER => [
'Authorization: Basic ' . $apiKey . ':'
],
or with
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, $apiKey . ":");

Edit: from your link in comment, they are expecting raw data of your request which you can accomplish by sending it as put request:
curl_setopt($ch,CURLOPT_CUSTOMREQUEST,'PUT');
or with text/plain header

**
- ***UPDATED***
**
are you encoding the API key as "base64" ??
$YOUR_API_KEY = base64_encode("YOUR_API_KEY");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://app.useanvil.com/api/v1/fill/XnuTZKVZg1Mljsu999od.pdf');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{ \"title\": \"Hello\", \"data\": [ { \"label\": \"Hello World\", \"content\": \"I like turtles\" } ] }");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_USERPWD, $YOUR_API_KEY . ':' . '');
$headers = array();
$headers[] = 'Content-Type: application/json';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
curl_close ($ch);

Easiest way to do add api key in curl request is as follow
// Collection object
$ch = curl_init($url);
$headers = array(
"APIKEY: PUT_HERE_API_KEY",
"Content-type: text/xml;charset=\"utf-8\"",
"Accept: text/xml"
);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlreq);
$result = curl_exec($ch); // execute
$result;
//show response
curl_close($ch);

Answer 4

curl -X GET -k -H 'Content-Type: application/json' -H 'X-ApiKey : YOUR_APIKEYHERE' -i 'YOUR API RNDPOINT URL HERE'
X-ApiKey is the name of your API key.
