Issues with parsing response json output with php

Hello all. I am new to the VDP APIs and I am running into issues trying to read the output of the response as a json using php. I followed the tutorial here. I am using the Offers Data API.

My goal is to be able to generate a list of deals to be displayed in the frontend. I am trying to do this by reading the json output and parsing the info for the deals.  

This is what the original tutorial had and it works fine:

$response = curl_exec($curl);  //This output contains the json output as well

$response_info = curl_getinfo($curl); 

To get the information, I am running: $response_data = file_get_contents($response); which does not appear to work. Since the output it not just the json, but with other info, I am not able to run: $arr = json_decode($response,true); to pasrse the json. 

Please let me know what I can do to fix this, or if there is a better way to accomplish the goal.  Thank you!

Hi @MiPlayer123,

 

Please try to use an API client tool first so you can test and trouble errors/issues easily. You can use VDC Playground, Postman, SoapUI or any other tool that you are familiar with. Please see user guides below for respective tools.

Hope this helps, please let me know if you have any questions.

Re: Issues with parsing response json output with php

Thank you all for your input. I use VDP playground to test the APIs. The issue I was having was parsing the data into a json. I have since resolved the issue as follows: 

$json = json_decode($response, true);

var_dump($json['Offers']); //This is only to display offers array

 

Here is the loop that I used to print the data:

$offers = $json["Offers"];

foreach ($offers as $x => &$offer) {
print($offer["offerId"]."<br>");
print($offer["offerTitle"]."<br>"."<br>");
}

 

Hope this helps others who run into the same issues.
