Actions By Email Connector

Plan Availability:

What is the Action By Email Connector?

Use the Actions By Email connector in your Process models to automate emails to Request participants that allow them make decisions via email.

When the Actions By Email connector triggers during an in-progress Request, ProcessMaker Platform sends an email from the "no-reply@processmaker.net" email address to one email recipient so that this Request participant can make a decision as part of the Request. For example, this Request participant must make a decision to approve or deny a vacation request or for a purchase. The email recipient receives an email with buttons in the email to easily indicate the decision.

Example email the Actions By Email connector sends to an email recipient

Email design is subject to email client limitations and may not fully support HTML5 or CSS3 specifications. Test your emails in your supported client applications.

While the Actions by Email connector can send the email to multiple email recipients, ProcessMaker Platform registers only the first response. The emails are sent using the Email Default settings, while the response is received using the Actions By Email settings.

After the email recipient clicks a button to indicate the decision, the email client creates an email reply to be delivered to the ProcessMaker Platform instance that used the Actions By Email connector. As indicated in the email reply, do not change anything below the automatically generated response because this response notifies the ProcessMaker Platform instance of the email recipient's decision for Request routing.

Automatically generated email reply the email recipient sends to the ProcessMaker Platform instance

After the email recipient sends the reply email, ProcessMaker Platform receives the response and uses the indicated decision as part of the Request routing. For example, if you grant a leave request, the Request routes differently than if you deny that leave request.

The comment in the email reply above the indicated line is not preserved when the email reply is sent. This comment displays only for the benefit of the email recipient prior to sending the email reply.

The Actions By Email connector adds the Actions By Email connector below the BPMN 2.0 elements in the panel to the left of the Process Modeler canvas. See the following sections in this topic:

The recipient's email address and/or subject can be specified in one of the following ways when configuring the Actions By Email connector:

Plain text
A Variable Name setting value using mustache syntax, for example {{ email_recipient }} and {{ email_address }}, respectively
A Magic Variable value, specifically {{ _user.fullname }} and {{ _user.email }}, respectively

The Actions By Email connector can send the email to multiple recipients. These email recipients and their email addresses may be referenced from Request data or entered into connector settings.

When an Actions By Email connector triggers during an in-progress Request, ProcessMaker Platform automatically creates an asynchronous child Process: the Actions By Email connector sends the email (the child Process) while simultaneously the in-progress Request continues (the parent Process). In doing so, one of the following occurs:

An error occurs in the email delivery: While attempting to send the email, the Actions By Email connector receives an error. For example, your organization's email server or the email recipient's email server may be down. The child Process receives and sends the error to the parent Process. The child Process ends. Reference the child Process's error from the in-progress Request.
The Actions by Email connector sends the email: The email recipient receives the email while the in-progress Request continues (the parent Process). The child Process ends, but the email recipient may not have responded to the email. If the in-progress Request routes to an Exclusive Gateway element that requires the email recipient's response to evaluate routing, then the in-progress Request remains indefinitely active on the Exclusive Gateway element.

To ensure that Requests do not remain indefinitely active on an Exclusive Gateway element while the Request waits for the email recipient's response, design your Process model to use an Event-Based Gateway element preceding the Exclusive Gateway element that checks the following:
If an Intermediate Timer Event element triggers (after 72 hours, for example), the email recipient has not responded to the email. Thereafter, design in the Process model how to address this, such as sending a subsequent email using the Send Email connector.
If an Intermediate Message Catch Event element triggers instead of the Intermediate Timer Event element, the email recipient sent the response within the allotted time period.

Loop Characteristics Panel Settings

Specify Characteristics to Perform Multiple Instances of the Task

Use the Loop Characteristics panel settings to specify how to perform multiple instances of this element. The following loop modes are available for this element:

No Loop Mode: Select the No Loop Mode option to perform this element's Task only once.
Loop: Select the Loop option to sequentially repeat this element's Task multiple times until an exit condition is True. This is useful when a Task should be performed multiple times with the same set of data, such as, processing a credit card payment. This loop mode has the following characteristics:
- The element's Task is repeated until the exit condition is True or the maximum iterations limit is reached.
- At any given time, only one instance of the Task is active. The subsequent instance does not begin until the current instance completes.
- The same exit condition evaluates at the end of each instance; however, value(s) of the Request variable(s) used in the exit condition can change during an instance resulting in the exit condition to eventually evaluate as True.
- If any one instance of that Task does not complete, workflow pauses.
- All active instances are terminated if an interrupting boundary-type event element triggers.
- An element configured in this mode shows the Loop icon in Process Modeler.
Multi-instance (Parallel): Select the Multi-instance (Parallel) option to perform this element's Task multiple times in parallel a fixed number of times. This is useful when performing any action in bulk, such as sending an email to several people. This loop mode has the following characteristics:
- Instances of the Task are governed by the size of an array-type Request variable where a new instance is created for each item in this variable. For example, an array with 10 items will create 10 parallel instances of this Task that each contains data from its respective array index.
- All instances begin simultaneously when this element triggers; however, they perform their Task independently of each other.
- The Task as a whole completes when all instances are complete.
- The output from each instance can either be saved in the source Request variable or a new array-type Request variable.
- All active instances terminate if an interrupting boundary-type event element triggers.
- An element configured in this mode shows the Multi-instance (Parallel) iconin Process Modeler.
Multi-instance (Sequential): Select the Multi-instance (Sequential) option to perform this element's Task multiple times sequentially a fixed number of times or until an exit condition is True. This is useful when sequentially repeating a Task multiple times but with a different set of data each time. This loop mode has the following characteristics:
- Instances of the Task are governed by the size an array-type Request variable where a new instance is created for each item in this variable. For example, an array with 10 items will create 10 parallel instances of this Task that each contains data from its respect array index.
- At any given time, only one instance of the Task is active. The subsequent instance does not begin until the current instance completes.
- At the end of each instance an exit condition evaluates and the loop activity halts if the exit condition is True.
- The Task as a whole completes when all instances are complete.
- The output from each instance can either be saved in the source Request variable or a new array-type Request variable.
- All active instances terminate if an interrupting boundary-type event element triggers.
- An element configured in this mode shows the Multi-instance (Sequential) iconin Process Modeler.

‌Follow these steps to specify characteristics to perform multiple instances of the Task:‌

- Multi-instance (Parallel): Select the Multi-instance (Parallel) option. The settings for this loop mode display:
  Follow these steps:
  1. In the Request Variable Array setting, enter the name of an array-type Request Variable. The size of this array will determine how many times this loop iterates.
  2. In the Output Data Variable setting, enter the name of an array-type Request variable in which to store the results of all instances. Each instance of the loop saves to a separate JSON object within the array of the specified Request variable. If the Output Data Variable setting is not configured, then the output data replaces the source data in the Request Variable Array.
- Multi-instance (Sequential): Select the Multi-instance (Sequential) option. The settings for this loop mode display:
  Follow these steps:
  1. In the Request Variable Array setting, enter the name of an array-type Request Variable. The size of this array will determine how many times this loop iterates.
