Warning: Google deprecated Gmail Contextual Gadgets on August 1, 2018. Gmail Contextual Gadgets impacts ProcessMaker's Google Integration functionality. Please refer to the ProcessMaker's Actions by Email feature for functionality that might meet your needs.


The ProcessMaker Google Integration extension for Chrome fully integrates ProcessMaker services with Google applications to make case management easier. This extension is available at the Google web store and it adds a convenient toolbar shortcut at the top left-hand side of the browser.

After successfully connecting to ProcessMaker, it is important to set Cron Jobs to a regular interval to synchronize the information between your ProcessMaker server and your Gmail account. With this, the integration is complete and functional.

The extension adds the HOME ProcessMaker trays to Gmail so you receive, view and work on your cases directly from the Gmail interface. You can manage, review and route cases directly from Gmail without logging to ProcessMaker. The extension also adds a field at the top of the Gmail email list, so you can easily find your processes, start new cases and bookmark the necessary processes so they are easily accessed from the ProcessMaker bookmark icon (next to the field).

Take into account that you must be logged into Google Chrome with the Google account with which you are registered in ProcessMaker. Also, it is recommended to always work with the latest version of the Google Chrome browser.

This functionality is available for Corporate and Enterprise editions.


The following are the requirements needed for this feature:

  • ProcessMaker version 3.1 or later: The ProcessMaker server must be with the SSL certificate, thus the server must use the https protocol.
  • Gmail Account: This Google account must be specified in the profile information of the user in ProcessMaker.
  • To use the service account, your company must subscribe to Gmail such that Google Gmail manages all your corporate email accounts.
  • ProcessMaker Google Integration extension.

Browser Requirements:

  • Google Chrome: This extension has been tested in version 46; however, it is always recommended to work with the latest version.

The ProcessMaker Field in Gmail and Process Bookmarks

After configurations to connect ProcessMaker are saved and the page refreshed, a field adds on the top left-hand side of the email list along with the ProcessMaker button as shown in the image below.

This field allows searching for processes that can be started by you (meaning that you are assigned to an starting task in the process). All coincidences of the text entered show down. Also, by clicking on the down arrow of the field, the complete list of processes, which you are assigned to start a task, displays.

Notice that next to the name of the processes in the list there is a star icon with plus sign inside. By clicking this icon, the process is added as a new bookmark in the process preferences of the user.

These bookmarks can be easily accessed by clicking the ProcessMaker icon next to the field. To remove a bookmark from this list, simply click the star icon with the minus sign inside.

Starting New Cases

The integration gives you the ability to start cases to which they are assigned directly from Gmail.

To start a new case, click the name of the process from the list shown in the field or from the user bookmarks.

A modal window opens showing the first step in the task (which could be a Dynaform, an Input Document or an Output Document). All steps of the task show in this window.

If at any point of the steps, before routing the case, this window is closed, it will be saved in the DRAFT label as an inbox email just like in ProcessMaker.

The last step in all cases of ProcessMaker is the routing of the case. In this window the information of the next task and the next assigned user is shown.

To route the case to the next task, click Continue.

Now, the information of the case is shown in the window. This means that the case has been routed correctly. So, simply close the window to continue.

Managing Cases from Gmail

Notice that after installing the extension, the ProcessMaker category is added to the Inbox section of the interface. This category has its own ProcessMaker labels (the same as shown to an Operator user in ProcessMaker.)

These labels are the following:

  • Draft: This label includes cases that are being edited or advanced by the user but have not yet been submitted to the next task. In ProcessMaker 3, only cases in their initial task may have the "Draft" status.
  • Inbox: This label includes cases that are currently placed in the user's Inbox.
  • Participated: This label includes the participated cases (cases in which the user has participated, meaning that the case was assigned to work on at least one of the tasks in the case).
  • Unassigned: This label includes the unassigned cases to which the user account is assigned in the task and can decide to claim the case as their own.

See more information of the states of cases in the ProcessMaker Cases page.

Note: It is recommended to avoid changing the name of the ProcessMaker labels. In case of changing the label name, a new ProcessMaker label is automatically created with the original name.

The management of these cases is similar to the management of emails in Gmail.

The difference is that when opened, the information of the case is shown:

The available tabs are the following:

  • Form: If the task has forms as steps, they are shown in this tab (including the routing window).
  • Process Map: It shows the workflow of the process highlighting the current task.
  • Uploaded: It shows the Input Documents related to the case.

  • Generated: It shows the Output Documents related to the case.

After routing a case to the next task, or finishing it, the case properties show and the case is marked as "read" (as with emails in Gmail) in the list. If opening the information of the case and not routing it, the case also is marked as "read" in the list.

Searching for Cases

The integration also allows to search for cases from the search field in Gmail.

To search a case, enter the number of the case, the name of the process, or any searching criteria as used with emails in Gmail. For example, if looking for the number of the case:
