Introduction to Flows Query Language

Flows Query Language (FQL) can be used to parse and transform JSON data to get the fields and structure you want.

Passing data to the Evaluate block

The Record block holds formatted key-value pairs. The variable data_field has a value of input (input can be selected as a value when creating the variable), which enables the formatted data to be passed into the Evaluate block and queried. In this case, customer_info holds another record that has string values. FQL can be run in the Evaluate block to print out the values of customer_info.

Things you can do with FQL

The following sections show examples of things you can do with FQL:

• Getting basic values
• Conditional data selection
• Returning structured data
• Data manipulation

Using Postbot with FQL

Not sure how to write an FQL statement for your flow? Ask Postbot! Flows has support for artificial intelligence in FQL queries. Tell Postbot what you want to do using plain language, and Postbot will generate a FQL statement for you.

In the Evaluate block, select the Postbot icon . Enter your query as a plain text sentence and select Generate FQL. Postbot will suggest a query for you based on your prompt.
