Use FQL conditional logic to select data

You can use Flows Query Language (FQL) to filter for specific data in your responses. Multiple responses return in an array. Single responses return as a single record. Sample data and FQL examples are below.

Example JSON

The examples below use this JSON object:

    {
        "customer_info": {
            "customer_field": "Customer data",
            "unformated_customer_field": " customer \n stuff ",
            "total_value": "281.01",
            "associated_usernames": ["user1", "myuser", "online_user"]
        },
        "payments": [
            {
                "invoice_number": "101301",
                "date": "2022-09-11T16:12:34.494Z",
                "description": "recurring subscription",
                "amount": 110.48
            },
            {
                "invoice_number": "101302",
                "date": "2022-09-29T14:45:13.148Z",
                "description": "one time purchase",
                "amount": 24.49
            },
            {
                "invoice_number": "101303",
                "date": "2022-10-11T16:12:34.683Z",
                "description": "recurring subscription",
                "amount": 110.48
            },
            {
                "invoice_number": "101304",
                "date": "2022-10-12T11:45:22.182Z",
                "description": "recurring subscription deluxe",
                "amount": 35.56
            }
        ]
    }

Filter query results for objects with specific key-value pairs

The example below filters for objects in the payments array that have the key-value pair "description": "recurring subscription".

[
    {
        "invoice_number": "101301",
        "date": "2022-09-11T16:12:34.494Z",
        "description": "recurring subscription",
        "amount": 110.48
    },
    {
        "invoice_number": "101303",
        "date": "2022-10-11T16:12:34.683Z",
        "description": "recurring subscription",
        "amount": 110.48
    }
]

Navigate your filtered results

FQL uses the same syntax to navigate filtered query results as it does to navigate JSON data. The example below gets the values from the invoice.number fields in the payments array.

Return a single record

When a filter has a single result, it returns as a record instead of an array. The filter below returns a single result as a record.

Check if a field has a specific value

FQL can check if your query results have a specific key-value pair and return true or false. The example below checks the first item in the payments array for the key-value pair "description": "recurring".

Get only unique payment amounts

The $distinct function returns a single instance of any recurring values. In the example below, the 110.48 value appears twice in the data, but only once in the result.
