Cannot send REST API requests to my processes from postman [error 404]


I’m testing the trial version of the enterprise subscription of Flowable (v3.10.3), and I’m facing issues using the REST API service. I get the message " HTTP Status 404 – Not Found " for any endpoint that I use.

I’m setting up my HTTP request as shown in the picture below:

This is the response that I get on postman:

<!doctype html>
<html lang="en">

	<title>HTTP Status 404 – Not Found</title>
	<style type="text/css">
		body {
			font-family: Tahoma, Arial, sans-serif;

		b {
			color: white;
			background-color: #525D76;

		h1 {
			font-size: 22px;

		h2 {
			font-size: 16px;

		h3 {
			font-size: 14px;

		p {
			font-size: 12px;

		a {
			color: black;

		.line {
			height: 1px;
			background-color: #525D76;
			border: none;

	<h1>HTTP Status 404 – Not Found</h1>
	<hr class="line" />
	<p><b>Type</b> Status Report</p>
	<p><b>Message</b> The requested resource [&#47;flowable-rest&#47;service&#47;runtime&#47;process-instances] is not
	<p><b>Description</b> The origin server did not find a current representation for the target resource or is not
		willing to disclose that one exists.</p>
	<hr class="line" />
	<h3>Apache Tomcat/9.0.53</h3>


Can anyone please help?

Thanks in advance!

Hi @joaofmonteiro

Please use the dedicated enterprise forum for questions like this:

The REST url should look like this:


Hi @amporsim

Thank you so much for your help, I was now able to send requests from Postman correctly.
By the way, where can I find the source of the information that you provided me?

Thank you and Happy 2022 :grinning:
