My HealthOS API Example for PHP

Their API has sample code, but it's not for PHP, so it just takes some work to translate into PHP:

<?php

// POST Request Access Token 

$fields = array(
    'grant_type' => "client_credentials",
    'client_id' => "faf4ad2651a7906fee8fab4c682ecc2721e16cc05771d8b32c807050ff621972",
    'client_secret' => "eb6731289c24359adcc76a98ed643de0b6f48526a4d56071d9c9cdb3656c3a9a",
    'scope' => "public read write"
);

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'http://www.healthos.co/api/v1/oauth/token.json',
  CURLOPT_RETURNTRANSFER => TRUE,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_POSTFIELDS => json_encode($fields),
  CURLOPT_HTTPHEADER => array(
    "content-type: application/json"
  )
));

$json_response = curl_exec($curl);

curl_close($curl);

$response = json_decode( $json_response, TRUE );
$access_token = $response['access_token'];


// GET Search Medicines

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://www.healthos.co/api/v1/autocomplete/medicines/brands/" . urlencode('CROCIN 125 MG SUSPENSION'),
  CURLOPT_RETURNTRANSFER => TRUE,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTPHEADER => array(
    "authorization: Bearer " . $access_token
  )
));

$json_response = curl_exec($curl);

curl_close($curl);

$response = json_decode( $json_response, TRUE );

echo '<pre>';
print_r( $response );
echo '</pre>';

Notice how there are two requests, one for the authorization, and a second for the medicine search. I get these results:

Array
(
    [0] => Array
        (
            [name] => CROCIN 125 MG SUSPENSION
            [form] => ML of suspension
            [standardUnits] => 1
            [packageForm] => bottle
            [price] => 37.77
            [size] => 60 ML suspension
            [manufacturer] => Glaxo SmithKline Pharmaceuticals Ltd
            [constituents] => Array
                (
                    [0] => Array
                        (
                            [name] => Paracetamol
                            [strength] => 125 mg
                        )

                )

            [schedule] => Array
                (
                    [category] => OTC
                    [label] => It can be sold without a prescription
                )

            [id] => 586ab09f91c126fe056b693f
            [medicine_id] => 63GIV
            [search_score] => 2.097369
        )

)

your code seems to be working as in dashboard there is a request for crocin... WHEN i tried i'm getting blank screen without any error. why?

Brian Gottier Over a year ago

Did you run it all by itself? No other code? You may need to display errors and turn on error reporting in PHP to figure that out. What version of PHP? Do you have curl enabled? Also, I took out the error checking, because I was just trying to get it to work. It's possible that the API is not responding, or has banned you because of requests coming from all over the world. I don't know.

Actually, it is still running fine for me. I am on a Ubuntu 14.04 machine, with PHP 5.5.9. I'll go to my PHP 7 machine and check there.

user5405873 Over a year ago

thanks @Brain Gottier, thanks for the effort, because of your code got some understanding. thanks once again

Brian Gottier Over a year ago

Your welcome. By the way, I'm now on a machine with PHP 7, and it works fine here too.

/api/v1/autocomplete/medicines/brands/CROCIN 125 MG SUSPENSION",

to

CURLOPT_URL => "http://www.healthos.co/api/v1/autocomplete/medicines/brands/CROCIN 125 MG SUSPENSION",

Try this

I added urlencode() to keep url intact.
I removed new line from original url.

$curl = curl_init();
    $url = "http://www.healthos.com/api/v1/autocomplete/medicines/brands/CROCIN 125 MG SUSPENSION";
    $endpoint = urlencode( $url );

curl_setopt_array($curl, array(
 // CURLOPT_URL => "http://www.healthos.co/api/v1/autocomplete/medicines/brands/CROCIN 125 MG SUSPENSION",
  CURLOPT_URL => $endpoint,
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "GET",
  CURLOPT_HTTPHEADER => array(
    "authorization" => "12b570970d786ebf07c85496f5d2a7212fca81799c93379c43066206b6780885"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error:" . $err;
} else {
  echo $response;
}

The URL is not correct kindly change the URL as following one

www.healthos.co is not a valid one. change into www.healthos.com

CURLOPT_URL => "http://www.healthos.com/api/v1/autocomplete/medicines/brands/CROCIN 125 MG SUSPENSION",
