FME Transformers: 2025.1
FME Transformers: 2025.1
TrelloConnector
Connects to Trello to manage boards, lists, and cards.
Typical Uses
- Adding workspace results to a board or card
- Retrieving board or card information to use in your workspace
- Creating complex or duplicated boards , lists, and cards
How does it work?
The TrelloConnector uses your account credentials to connect to Trello and perform various tasks:
Action |
Task |
---|---|
Archive |
Archive a board , list, or card . |
Create |
Create a new board , list, or card. Cards may receive coordinates from point geometry. |
List |
Retrieve details about boards, lists, or cards. Cards may include coordinates. |
Update |
Update an existing board, list, or card. Cards may receive coordinates from point geometry. |
Once valid account credentials have been provided, you may browse to available content for the selected Action. Item IDs may also be entered directly.
Configuration
Input Ports

This transformer accepts any feature.
If an input feature has point geometry, it will be used as coordinate data on a card when Action is Create or Update.
Output Ports

Features with added attributes, as specified in parameters and according to Action:
Action |
Output |
---|---|
Archive |
Input feature with details about the archived item. |
Create |
Input feature with details about the new item. |
List |
Multiple features, one for each item in the specified location, with details about the items. Coordinate data on cards will be added to the output feature as FME point geometry (LL-WGS84). |
Update |
Input feature with details about the uploaded item. |

Features that cause the operation to fail are output through this port. An fme_rejection_code attribute describing the category of the error will be added, along with a more descriptive fme_rejection_message which contains more specific details as to the reason for the failure.
If an Input feature already has a value for fme_rejection_code, this value will be removed.
Rejected Feature Handling: can be set to either terminate the translation or continue running when it encounters a rejected feature. This setting is available both as a default FME option and as a workspace parameter.

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.

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.

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. |

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.
