Data Connector Connector

Access both Collection records and third-party data sources from Process models, then make workflow routing decisions based on that data.

Overview

The Data Connector connector is part of the Data Connector package. From the Data Connector connector, select a Data Connector from which to interact with a data source.
Use the Data Connector connector in your Process models in the following ways:
  • Access Collections: From your Process model, interact with any Collection in your ProcessMaker Platform instance, including viewing, creating, updating, and/or delete records in a selected Collection. By default, each Collection has a corresponding Data Connector when it is created. Incorporate Collection record data into your Process model so you can make business decisions using it. Likewise, automatically change records in a Collection during a Request when workflow routing conditions are met.
  • Access third-party data sources: Similarly to Collections, interact with third-party data sources such as Application Program Interfaces (APIs). Reference data from that API, then incorporate it into your Process's Request data. Incorporating data from external data sources helps you make business decisions from information outside of your ProcessMaker Platform instance.

Package and Permissions Required

The Data Connector package must be installed to use the Data Connector connector.
Furthermore, your user account or group membership must have the following permissions to configure a Data Connector connector to the Process model unless your user account has the Make this user a Super Admin setting selected:
  • Processes: Edit Processes
  • Processes: View Processes
See the Process permissions or ask your Administrator for assistance.

Add a Data Connector Connector to the Process Model

    Ensure that the Configuration panel displays. If not, show it. The Name setting displays.
  3. 3.
    In the Name setting, edit the selected connector's name and then press Enter.

Select the Data Connector

The Data Connector connector uses a Data Connector that is configured to interact with a data source, such as a Collection or a third-party Application Program Interface (API). A Data Connector must already exist before it can be selected for use in a Data Connector connector. Each Data Connector is already configured with which data source it interacts.
Collections automatically create a Data Connector when the Collection is created. Data Connectors created from a Collection by default have the same name as the Collection that it references.
Follow these steps to select the Data Connector the Data Connector connector uses:
  1. 1.
    Select the Data Connector connector from the Process model in which to specify the Data Connector to reference.
  2. 2.

Ensure to select which of the Data Connector's Resources interacts with the data source to properly configure the Data Connector connector.

Select the Resource the Data Connector Connector Uses to Interact with the Data Source

Each Data Connector contains at least one Resource. These Resources are configured from the Data Connector itself. A Resource is an action the Data Connector uses to interact with the data source. The Data Connector connector uses a Resource to interact with the data source. These Resources may interact with Collection records, Application Program Interfaces (APIs), or other data source types. After a Data Connector has been selected from the Select a Data Connector setting, select the Resource from that Data Connector the Data Connector uses to interact with the data source.
Data Connectors created from Collections use a default set of Resources. See Resources for Collections.

Data Source properties configured to receive data from the Data Connector connector

Map Data from the Data Source to the Request's JSON Data Model

Configure how data from the data source integrates with Request data.
Ensure that you have configured the following before configuring outbound properties, in this order:
The procedure to integrate the data source's data to the Request JSON data model is called response mapping: specifying into which Request variable to store the data source's data. The Data Connector may be configured with response mapping, whereby a specified source name in the body or header of the data source response's is mapped to store that value in a specified Request variable. By relying on the Data Connector's response mapping, the Process designer only needs to select the Request variable name as mapped in the Data Connector's response without knowing technical details for this mapping.
Each JSON object contains a key name that references the JSON object, and the value for that key. If the JSON object already exists in a Request's JSON data model, then the Data Connector connector overwrites the existing JSON object value with that from the data source. If the JSON object(s) to map the data source data does not exist, then the Data Connector connector adds the JSON data object(s) to that Request's JSON data model.
Follow these steps to specify the Request JSON data object(s) to which to map the data source's data:
  1. 1.
    Select the Data Connector connector from the Process model to map the data source's data to the Request JSON object(s).
  2. 2.
    Ensure that the Configuration panel displays. If not, show it. Panels to configure this element display.
  3. 3.
    Expand the Data Connector panel if it is not presently expanded. The Response Mapping setting displays.
  4. 4.
    Click the
    icon to add a JSON object to which to map data from the data source. The Source and Set to Request Variable settings display to add the JSON source name and its variable, respectively, for the JSON object.
  5. 5.
    In the Source setting, enter the name of the source from which to store the response. If the source is from Request data, such as from a Collection, the source name is data. data is the name of the JSON object that stores all data for each Request. However, the Source setting corresponds with how the Data Connector maps the data response: by selecting a mapped Request variable from the Set to Request Variable setting below, its corresponding source name displays in the Source setting. Optionally, specify the source name as a Request variable using mustache syntax.
  6. 6.
    In the Set to Request Variable setting, enter the Request variable as configured in the Data Connector's response mapping in which to store the data source's response. Optionally, specify the source name as a Request variable using mustache syntax. After doing so, the Source setting displays the source's name configured for that response mapping.
  7. 7.
    Click Save.
  8. 8.
    Repeat Steps 4 through 6 for each Request variable to store the data source's response.
Click the Delete icon
to delete a mapped response from the Response Mapping setting.

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) icon
      in 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.
    • An element configured in this mode shows the Multi-instance (Sequential) icon
      in Process Modeler.
‌Follow these steps to specify characteristics to perform multiple instances of the Task:‌
  1. 1.
    Select the element from the Process model in which to specify multiple instance characteristics.

      2. 2.
        In the Exit Condition setting, enter a condition in FEEL syntax. When this condition is True the loop activity is halted.
    • Multi-instance (Parallel): Select the Multi-instance (Parallel) option. The settings for this loop mode display:
      Follow these steps:
      1. 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. 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. 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. 2.
        In the Exit Condition setting, enter a condition in FEEL syntax. When this condition is True the loop activity is halted.
      3. 3.
        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.

Callback Panel Setting

Configure the Server Callback

Configure how the Data Connector connector automatically calls back the data source by enabling the Wait for server callback setting with a callback. A callback automates receiving data from the data source, such as a third-party service, and then subsequently sending back data to that data source. The Data Connector connector monitors for data from the data source via a unique URL that may be stored in a Request variable. Likewise, the data that the Data Connector connector sends to the data source as a response may be stored in a Request variable. Configure the callback to use GET and/or POST methods to retrieve and/or send data, respectively.
In overview, a callback functions as follows:
  • A Data Connector connector interacts with a data source, such as the third-party service Stripe that automates payment services. For example, a Request participant has submitted information for a payment via a Task earlier in that Request.
  • The Request pauses while the Data Connector connector waits for the data source to respond. The connector monitors for that response. For example, Stripe responds that the submitted payment is accepted or rejected. The third-party service is the Data Connector's data source.
  • After the third-party service processes its data and responds to the Data Connector connector, the connector calls back that data source: the connector may get data or post data to that third-party service.
For example, consider a course enrollment process where each student selects courses for that semester and then must pay for tuition. After enrolling in courses, a Task presents the student with a final invoice and payment options. When the student submits payment, the Request invokes a payment service's Application Program Interface (API), such as Stripe, to verify the payment. Use a Data Connector connector callback to monitor when the payment service's API verifies the payment information entered by the student. The Request now waits for a response from the payment service's API. The API response returns to a Request variable which can be used to determine next steps in that Request. If the student entered correct payment information and payment is honored, then their course enrollment is confirmed; otherwise the student must re-enter their payment details.
Follow these steps to specify a Data Connector connector's callback to the data source:
  1. 1.
    Select the Data Connector connector from the Process model in which to configure the server callback.
  2. 2.
    Ensure that the Configuration panel displays. If not, show it. Panels to configure this element display.

  5. 5.
    In the Variable Name for Callback URL setting, enter the URL that the data source calls to trigger a callback to the Data Connector connector. This URL may be stored in a Request variable that must be encapsulated using mustache syntax.
  6. 6.
    In the Response Variable Name setting, enter the Request variable name within mustache syntax that stores the response from the data source. If the response is JSON, the Request variable stores the response as a JSON object. Otherwise, the Request variable stores the response as text.
  7. 7.
    In the Accepted methods setting, toggle the GET and/or POST methods as the callback to retrieve and/or send data, respectively.
  8. 8.
    In the Authentication drop-down menu, select one of the following authentication methods:
    • None: Select the None option if no authentication is required.

      Follow these steps to enter basic authentication credentials:
      1. 1.
        In the Username setting, enter the username to authenticate with the data source.
      2. 2.
        In the Password setting, enter the password to authenticate with the data source.
  9. 9.
    In the Allow Access From setting, enter the server URLs from where the Data Connector connector accepts callbacks. If a server URL is not included in the Allow Access From setting, then the Data Connector connector does not accept the response.
    Follow these guidelines to manage server URLs:
    • Click the Delete
      icon to delete an added server URL.
    • Click the Add
      icon to add an additional server URL.

Edit the Node's Identifier Value

A Process node represents a component of a Process model, whether that is a BPMN element or a connector. Process Modeler automatically assigns a unique value to each Process node added to a Process model. A Process node's identifier value can be changed if it is unique to all other nodes in the Process model, including the Process model's identifier value.
All identifier values for all nodes in the Process model must be unique.
Follow these steps to edit the identifier value for a Data Connector connector:
  1. 1.
    Select the Data Connector connector from the Process model in which to edit its identifier value.
  2. 2.
    Ensure that the Configuration panel displays. If not, show it. Panels to configure this element display.
  3. 3.
    Expand the Advanced panel if it is not presently expanded. The Node Identifier setting displays. This is a required setting.
  4. 4.
    In the Node Identifier setting, edit the Data Connector connector's identifier to a unique value from all nodes in the Process model and then press Enter.
