How to submit contact form 7 programmatically - wordpress

Question

I want to submit contact form by custom function
The code below is getting the instance of form but when submitted. It submit the form but not the fields which I wanted.
$item = wpcf7_contact_form( $formId );
$result = $item->submit();
Here where I can pass the fields I define in admin panel like "textarea-123" & "email-234" ?

Answer 1

I did not get exact answer for what I look but I found the alternate solution.
function cf7Submit($formId , $args) {
$url = 'http://example.com/wp-json/contact-form-7/v1/contact-forms/'.$formId.'/feedback';
$response = wp_remote_post( $url, array(
'method' => 'POST',
'body' => $args
)
);
if ( is_wp_error( $response ) ) {
$error_message = $response->get_error_message();
echo "Something went wrong: $error_message";
} else {
echo 'Response:<pre>';
print_r( $response );
echo '</pre>';
}
}
I can call this function like this:
cf7Submit(128, array(
'textarea-123' => 'test email',
'email-234' => 'asd#asd.com'));

#daraptoor has found a good solution, but as #davevsdave noticed in the comment, it does not work properly in CF7 5.6.
Error 415 is caused by added to API check for content type passed into a request header:
// part of create_feedback() from CF7's rest-api.php
if ( ! str_starts_with( $content_type, 'multipart/form-data' ) ) {
To figure it out, just add the expected content type into a request header:
$response = wp_remote_post( $url, array(
'method' => 'POST',
'headers' => array(
'Content-Type' => 'multipart/form-data'
),
'body' => $args
)
);
UPD
Faced with an issue, that wp_remote_post() send data in body and not in POST, so CF7 API does not get any fields. It is caused because the WP's function uses http_build_query() (read more here).
I have used cURL request as a workaround:
// Same user agent as in regular wp_remote_post().
$userAgent = 'WordPress/' . get_bloginfo('version') . '; ' . get_bloginfo('url');
// Note that Content-Type wrote in a bit different way.
$header = ['Content-Type: multipart/form-data'];
// Same array with fields to pass, not changed.
$body = ['foo' => 'bar'];
$curlOpts = [
// Send as POST
CURLOPT_POST => 1,
// Get a response data instead of true
CURLOPT_RETURNTRANSFER => 1,
// CF7 will reject your request as spam without it.
CURLOPT_USERAGENT => $userAgent,
CURLOPT_HTTPHEADER => $header,
CURLOPT_POSTFIELDS => $body,
];
$ch = curl_init($apiUrl); // Create a new cURL resource.
curl_setopt_array($ch, $curlOpts); // Set options.
$response = curl_exec($ch); // Grab response.
if (!$response) {
// Do something if an error occurred.
} else {
$response = json_decode($response);
// Do something with the response data.
}
// Close cURL resource, and free up system resources.
curl_close($ch);
Hope it saves someones time :)

You can add a piece of JS code, like:
$("form.wpcf7").submit()
