Unable to make CURL post request using PHP - php

Question

I read some Q&As but still struggling with this one. I need to post a specific array to an API and get another array as an answer.
UPDATE
I used :
<?php
echo 'Testing cURL<br>';
// Get cURL resource
$curl = curl_init();
$data=array(array("UserId"=>"xxxx-10100","Password"=>"pass"));
$sendpostdata = json_encode( array( "postdata"=> $data ) );
echo $sendpostdata;
// Set some options - we are passing in a useragent too here
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'https://cloud.servicebridge.com/api/v1/Login',
CURLOPT_HTTPHEADER => array('Accept: application/json','Content-Type: application/json'),
CURLOPT_USERAGENT => 'Codular Sample cURL Request',
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => $sendpostdata
));
// Send the request & save response to $resp
$resp = curl_exec($curl);
echo $resp;
// Close request to clear up some resources
curl_close($curl);
?>
This results in
Testing cURL
{"postdata":[{"UserId":"xxxxx-10100","Password":"pass"}]}
{ "Data": null, "Success": false, "Error": { "Message": "Invalid UserId: ", "Value": "InvalidUserId", "Code": 9001 } }
No console logs, no other messages or clues
I am trying to implement this API https://cloud.servicebridge.com/developer/index#/
to Worpdress.
The API requires a
{
"UserId": "string",
"Password": "string"
}
Can you help me out? What am I doing wrong
Really appreciate this,

I have checked the given API and it's REQUEST Parameters to access them and I think your initial data (username and password) is not going correctly. Please use this code:-
<?php
error_reporting(E_ALL); // check all type of errors
ini_set('display_errors',1); // display those errors
// Get cURL resource
$curl = curl_init();
$sendpostdata = json_encode(array("UserId"=>"xxxx-10100","Password"=>"pass"));
// Set some options - we are passing in a useragent too here
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'https://cloud.servicebridge.com/api/v1/Login',
CURLOPT_HTTPHEADER => array('Accept: application/json','Content-Type: application/json'),
CURLOPT_USERAGENT => 'Codular Sample cURL Request',
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => $sendpostdata
));
// Send the request & save response to $resp
$resp = curl_exec($curl);
echo $resp;
// Close request to clear up some resources
curl_close($curl);
?>
Note:- change UserId & Passwordvalues to your real values.Thanks

This might help you in generating proper json. Hope this will work.
use this
$data=array(array("UserId"=>"xxxxx-10100","Password"=>"pass"));
instead of
$data ='[{"UserId":"xxxxx-10100","Password": "pass"}]';
