I'm attempting to make a POST request to an API. I've created a javascript file in my theme and i have tried two approaches so far:
Approach 1:
$.ajax({
headers:{
"Content-Type":"application/json"
},
data:{
"command": "request",
"data": {
"api_key": "my_api_key",
"api_username": "my_api_username",
"vendor_type": 2,
"from": {
"from_name": "",
"from_lat": "",
"from_long": "",
"from_description": ""
},
"to": {
"to_name": customerLocation,
"to_lat": cityLat,
"to_long": cityLng,
"to_description": ""
},
"recepient": {
"recepient_name": name,
"recepient_phone": phone,
"recepient_email": email,
"recepient_notes": ""
},
"delivery_details": {
"pick_up_date": pickupdate,
"collect_payment": {
"status": false,
"pay_method": 0,
"amount": amountTotal
},
"return": true,
"note": " Sample note",
"note_status": true,
"request_type": "quote"
}
},
"request_token_id": requestToken
},
type: 'POST',
url:"/",
success: function(response){
console.log('success');
console.log(response);
},
error: function(response){
console.log('error');
console.log(response);
}
});
The above code will not return a response payload from the API as any call will be blocked because of CORS(Cross-Origin Resource Sharing)
Approach 2
I then attempt to pass the endpoint to my functions.php file as follows:
//make api call to sendy
function foo()
{
echo '/';
}
add_action('wp_ajax_foo', 'foo' );
add_action('wp_ajax_nopriv_foo', 'foo' );
I declare an ajaxUrl variable in my theme's header.php file:
<script type="text/javascript">
var ajaxUrl = "<?php echo admin_url('admin-ajax.php'); ?>";
</script>
Then format my Ajax call as shown below:
$.ajax({
headers:{
"Content-Type":"application/json"
},
data:{
"action": 'foo',
"command": "request",
"data": {
"api_key": "my_api_key",
"api_username": "my_api_username",
"vendor_type": 2,
"from": {
"from_name": "",
"from_lat": "",
"from_long": "",
"from_description": ""
},
"to": {
"to_name": customerLocation,
"to_lat": cityLat,
"to_long": cityLng,
"to_description": ""
},
"recepient": {
"recepient_name": name,
"recepient_phone": phone,
"recepient_email": email,
"recepient_notes": ""
},
"delivery_details": {
"pick_up_date": pickupdate,
"collect_payment": {
"status": false,
"pay_method": 0,
"amount": amountTotal
},
"return": true,
"note": " Sample note",
"note_status": true,
"request_type": "quote"
}
},
"request_token_id": requestToken
},
type: 'POST',
url:ajaxurl,
success: function(response){
console.log('success');
console.log(response);
},
error: function(response){
console.log('error');
console.log(response);
}
});
But this is giving me a 400 (Bad Request) error.
I should mention that i have correctly set up my javascript file in the functions.php file:
wp_enqueue_script('sendy', get_template_directory_uri() . '/assets/js/sendy.js', array('jquery'));
wp_localize_script('sendy', 'wc_checkout_params', array('ajaxurl' => admin_url('admin-ajax.php')));
Would like therefore to request for assistance in setting up my POST endpoint.

You got the error 400 Bad Request because the Content-Type header is application/json:
$.ajax({
headers:{
"Content-Type":"application/json"
},
data: {
...
},
...
});
And when the request content is a JSON string, the $_REQUEST['action'] which WordPress uses to identify the proper AJAX action (which is foo in your code) is not available (i.e. it's a NULL).
So based on your code, and with your second approach, you can just omit the headers part.
$.ajax({
// No "headers" here.
data: {
...
},
...
});
You can use wp_remote_post() to make the external API request from the foo() function; example:
function foo() {
if ( empty( $_POST['data'] ) ) {
wp_die( 'Missing data' );
}
$post_data = wp_unslash( $_POST['data'] );
$post_data['command'] = wp_unslash( $_POST['command'] );
$post_data['request_token_id'] = wp_unslash( $_POST['request_token_id'] );
$api_url = 'https://apitest.sendyit/v1/';
$response = wp_remote_post( $api_url, array(
// Set the Content-Type header.
'headers' => array(
'Content-Type' => 'application/json',
),
// Set the request payload/body.
'body' => json_encode( $post_data ),
) );
$res_body = wp_remote_retrieve_body( $response );
echo $res_body;
wp_die();
}
