FME Transformers: 2024.2
FME Transformers: 2024.2
FMEFlowNotifier
Sends a notification to a specified FME Flow instance.
This notification will trigger a topic which can then be used in an automation or with a subscriber. The topic may be used for a variety of actions, such as triggering a downstream workspace, or sending an email message to subscribed clients.
This transformer requires an FME Flow connection.
Performance Considerations
Windows systems may experience slow performance in situations where a high volume of notifications are sent. Performance may improve by disabling automatic proxy detection:
- Click the Start menu,
- In the 'Search programs and files' textbox, type 'proxy' and select 'Configure proxy server'.
- In the Internet Properties dialog, Connections tab, click LAN settings.
- Uncheck Automatically detect settings.
- Click OK.
Configuration
Output Ports
Output
Features are output through this port for every notification that was successfully sent. Each feature will have the following attributes exposed:
- _notifier_topic: Topic to be notified
- _notifier_content: The contents of the notification
<Rejected>
Features are output through this port when a notification fails to be sent. Each feature will have the following attributes exposed:
- _notifier_topic: Topic to be notified
- _notifier_content: The contents of the notification
- _failure_reason: If failed to send a notification, the failure reason
- _http_status_code: If failed to send a notification, the HTTP status code
Failure to successfully send a notification will not halt the translation.
Parameters
Connection
Connection |
You can connect to FME Flow in one of the following ways: Connection
Specify a web connection to FME Flow. Web connections can be reused in multiple workspaces, and connection parameters are hidden in the workspace. For more information, see Using Web Connections. SAML Authentication SAML (Security Assertion Markup Language) authentication is not available for these FME Flow transformers: See SAML Configuration and Automations for more information and alternatives. Embed Connection Parameters
When checked, you must specify the connection parameters to FME Flow manually. The connection parameters are visible in the workspace. To connect, specify: FME Flow URL
Enter a URL to access FME Flow. You may need to contact your System Administrator for the URL. Username and Password
Provide your FME Flow credentials. Note You can click the Status hyperlink to ensure that the FME Flow connection has been successfully established.

General
Topic |
This parameter is the notification topic. Different FME Flow notification subscriptions respond to different topics, so this topic eventually determines which actions are triggered. |
Content |
This parameter specifies the notification content. |
Editing Transformer Parameters
Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.
How to Set Parameter Values
Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.
Using the Text Editor
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
Using the Arithmetic Editor
The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.
Conditional Values
Set values depending on one or more test conditions that either pass or fail.
Parameter Condition Definition Dialog
Content
Expressions and strings can include a number of functions, characters, parameters, and more.
When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.
Content Types
These functions manipulate and format strings. | |
Special Characters |
A set of control characters is available in the Text Editor. |
Math functions are available in both editors. | |
Date/Time Functions | Date and time functions are available in the Text Editor. |
These operators are available in the Arithmetic Editor. | |
These return primarily feature-specific values. | |
FME and workspace-specific parameters may be used. | |
Creating and Modifying User Parameters | Create your own editable parameters. |
Dialog Options - Tables
Table Tools
Transformers with table-style parameters have additional tools for populating and manipulating values.
Row Reordering
|
Enabled once you have clicked on a row item. Choices include:
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers. |
Filter
|
Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output. |
Import
|
Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers. |
Reset/Refresh
|
Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers. |
Note: Not all tools are available in all transformers.
For more information, see Transformer Parameter Menu Options.
