Using helpers

Helpers are action templates that allow you to transform variables, for example, convert a string into an array, or perform additional data validation, for example, check business hours.

A helper needs to be configured in the Data modification block. For that, create a variable or modify an existing one. As a variable value, you can write both variables and plain values. Use single quotes for plain values.

Rounds up to a whole number.

Format: {{CEIL variable}}

Example, where variable test = 2.344:

{{CEIL 5.344}} >>> 6
{{CEIL test}} >>> 3
{{CEIL -1.1}} >>> -1

Rounds down to a whole number.

Format: {{FLOOR variable}}

Example, where variable test = 2.344:

{{FLOOR 5.344}} >>> 5
{{FLOOR test}} >>> 2
{{FLOOR -1.1}} >>> -2

Checks if the current time falls within the specified range. You can use this helper to control the time of placing/forwarding calls, etc. For the helper to work correctly, use it in combination with the Data verification block.

Format: {{CHECK_HOURS from to timezone type}}, where:

A variable with the CHECK_HOURS helper can take the value of 1 or 0.

Example:

{{CHECK_HOURS '09:30''19:30''+3''weekdays'}} >>> 1 or 0

In the example, the variable will take the value of 1 on weekdays from 9:30 am to 7:30 pm (timezone +3). In other cases, it will take the value of 0.

Compares two values/variables:

Format: {{#COMPARE v1 operator v2}} if_true {{else}} if_false {{/COMPARE}}, where:

It is required to explicitly define values returned during comparison (e.g., 'yes' if the condition is met and 'no' in other cases).

Example:

{{#COMPAREorder_found\'==\'\'yes\'}} order found {{else}} order not found {{/COMPARE}} >>> order found

Performs math operations: addition, subtraction, multiplication, division ('/'), exponentiation ('^'), remainder of division ('%'), and trigonometric functions (sin, cos, and tan).

Format: {{#CALC}} equations {{/CALC}}

Variables inside CALC must be in double curly brackets.

Example, where variable price=10:

{{#CALC}} '+'{{price}} * 5'+'{{/CALC}} >>> 50

Converts a date from one format to another.

Format: {{DATE_CONVERT date old_format new_format}}

Available date formats and how they display:

Example, where the original date is 12:00 23.01.2018 and the original format is HH:mm DD.MM.YYYY:

{{DATE_CONVERTorder_data\'HH:mm DD.MM.YYYY\'\'DD/MM/YYY\'}} >>> 25/12/2019

Creates a new array using the values of an old array based on a certain key.

Format: {{PLUCK array key value}}

Example, where variable array_sample = [{"id": 1, "value": "q"}, {"id": 2, "value": "w"}, {"id": 3, "value": "e"}]:

{{PLUCK array_sample 'id'}} >>> [1,2,3]

Filters data by a specific parameter and its value. Returns a new array; the initial data does not change.

Format: {{FILTERBY array key value}}

Example, where variable array_sample = [{"id": 1, "value": "q"}, {"id": 2, "value": "w"}, {"id": 1, "value": "e"}]:

{{FILTERBY array_sample 'id' 1}} >>> [{"id":1,"value":"q"},{"id":1,"value":"e"}]

Finds the first array element that satisfies the provided key value.

Format: {{FINDBY array key value}}

Example, where variable array_sample = [{"id": 1, "value": "q"}, {"id": 2, "value": "w"}, {"id": 3, "value": "e"}]:

{{FINDBY array_sample 'id' 1}} >>> {"id": 1, "value": "q"}

Converts an array to a string with a delimiter.

Format: {{JOIN array separator}}

Example, where variable test = ["summer","autumn","winter","spring"]:

{{JOIN test '|'}} >>> summer|autumn|winter|spring

Displays the length of a string/array.

Format: {{LENGTH str}}

Example, where variable test_str = 'text example'; variable test_array = ["apple", "banana", "carrot", "coconut"]; variable test_obj = {"key1": 1, "key2": 2, "key3": 3}:

{{LENGTH test_str}} >>> 12
{{LENGTH test_array}} >>> 4
{{LENGTH test_obj}} >>> 3 (number of keys)

Converts a string to lowercase.

Format: {{LOWERCASE str}}

Example, where variable test = 'WONDERFUL order':

{{LOWERCASE test}} >>> wonderful order

Converts a string to uppercase.

Format: {{UPPERCASE str}}

Example, where variable test = 'WONDERFUL order':

{{UPPERCASE test}} >>> WONDERFUL ORDER

Removes all non-digits from a string.

Format: {{PHONE_FORMAT str}}

Example, where variable test = '+1-474 000 00-00':

{{PHONE_FORMAT test}} >>> 14740000000

Replaces one string value with another.

Format: {{REPLACE str A B}}

Example, where variable test = 'John':

{{REPLACE 'Hello, my name is NAME''NAME'test}} >>> Hello, my name is John

Reverses a string/array.

Format: {{REVERSE variable}}

Example, where variable test_str = 'Some text'; variable test_arr = [1,2,3,4,5]:

{{REVERSE test_str}} >>> txet emoS
{{REVERSE test_arr}} >>> [5,4,3,2,1]

Sorts array values in ascending order. The system first sorts numbers, then letters.

Format: {{SORT array}}

Example, where variable test_array = ['banana', 'apple', 'coconut', 'carrot']:

{{SORT test_array}} >>> ["apple","banana","carrot","coconut"]
{{SORT test_array reverse=1}} >>> ["coconut","carrot","banana","apple"]

Sorts an array by a specific argument in ascending order. Similarly to SORT, use the option reverse = 1 for descending order.

Format: {{SORTBY array key}}

Example, where variable array_sample = [{"id": 1, "value": "z"}, {"id": 2, "value": "a"}, {"id": 1, "value": "x"}]:

{{SORTBY array_sample 'value'}} >>> [{"id":2,"value":"a"},{"id":1,"value":"x"},{"id":1,"value":"z"}]

Converts a string to an array specifying a delimiter.

Format: {{SPLIT str separator}}

Example, where variable test = 'summer;autumn;winter;spring':

{{SPLIT test';'}} >>> ["summer","autumn","winter","spring"]
