Execution: Remote over HTTP Handler

This feature allows you to execute Workflow from any System, which could initiate HTTP Post Requests. You could also submit any values to the workflow and access these variables from every task.
This allows a very flexible Webservice System you could configure in vtigerCRM Frontend.

You could execute single Workflows by ID or trigger a custom trigger, which could be managed via trigger configuration.

use cases

  • replacement of Webservice for Record Creation, like Forms on Webpage for Lead collection
  • like Forms on Webpage for Lead collection
  • execute special processes from webpage (External Administrations) if the record ID of organization is known (generation of quotes, …)

Security & Configuration

The access to the HTTP Handler is denied per default for all IP's.
If you want to use such handler, you must grant access for single IP's/IP Ranges to execute a specific trigger/workflow.
This configuration could be done in the Workflow Designer configuration on “Settings HTTP Handler”.
If you press “new permission” or “edit” you will see the following form.

Workflow selection

To configure the Workflow/Trigger you want to execute, use the following GET Variables:

If you don't want to connect a record, set the record_id = 0

Examples
ВYou want to execute a single workflow with no special connected record (You want to create a new lead) use

?record_id=0&workflow_id=<IDofWorkflow>

submit Variables

To submit variables to the workflow only use POST variables to transfer data.
The values could be used inside the executed workflows in the $env variable.

For example if you submit a variable lastname to the workflow, you could access the variable in every task of this workflow by using

$env[“lastname”]

.

PHP Example

$url = '<urlofvtigerCRM>/<shorturl>?<ExecutionConfiguration>';
 
$fields = array(
   'firstname' => "Firstname",
   'lastname' => "Lastname",
   'street' => "streetname 123"
);
 
foreach($fields as $key=>$value) {
  $fields_string .= $key.'='.urlencode($value).'&';
}
rtrim($fields_string, '&');
 
$ch = curl_init();
 
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$result = curl_exec($ch);
curl_close($ch);

You want to execute the workflow with the ID 77 on the record 852 you need to write:

$url = '<urlofvtigerCRM>/<shorturl>?record_id=852&workflow_id=77';
 
$fields = array(
   'firstname' => "Firstname",
   'lastname' => "Lastname",
   'street' => "streetname 123"
);
 
foreach($fields as $key=>$value) {
  $fields_string .= $key.'='.urlencode($value).'&';
}
rtrim($fields_string, '&');
 
$ch = curl_init();
 
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$result = curl_exec($ch);
curl_close($ch);
