The Evaluate block

The Evaluate block is a powerful tool for manipulating and evaluating data within your flow. It's ideal for filtering data, conditionally executing parts of your flow, and integrating complex logic.

Using Flows Query Language (FQL) queries or TypeScript scripts, you can set up the Evaluate block to process data and send the result. The Evaluate block has pre-defined snippets to help you create FQL queries.

Input

variable - This input port accepts data from another block's output port. When this port is connected to another block, the Evaluate block inserts a Select block and assigns the selected value to a variable named value. To rename the variable, select it and enter a new name.

Output

Result - Sends the result of the script or query.

Setup

The Evaluate block can process data it receives from its input ports and inserted data blocks. When you create an Evaluate block, it has one input port next to a variable name. When you connect the input port to another block's output port, the Evaluate block inserts a Select block for the incoming data and creates a variable named value. To rename the variable, select it and enter the new name. You can also change the inserted Select block to a different data block by selecting the Select block's icon and choosing a data block from the dropdown list.

You can also insert more data blocks into the Evaluate block to process their data. For example, you could insert a String block into your Evaluate block, name the variable string1, and reference it in your query as string1. Select Add data blocks to insert a data block into your Evaluate block.

The Evaluate block has a text box where you can enter FQL or TypeScript code to create queries or scripts. Select the dropdown list at the top of the block to set the text box to use TypeScript or FQL. Then select the text box and enter your code. When the text box is set to use FQL, you can select Snippets and choose from a list of common tasks.
