Studio Flow

We generate some of the variables in flow process, those can used to pass the information your system.

Varibles consist of alphanumeric characters and underscores, should always start with a letter, and do not have any kind of leading sigil (that is, they look like var_name, not $var_name). Also variables should not consist of backslash(’') as our application treats the backslash as an escape character by default.

All variables should be enclosed between a set of double curly braces {{}} braces. ex: @{{to}} You can access the Array of the variables with . dot notation.


Name Scope Description
id global Sms unique id
text global Sms send by the customer
from global Sms from number with country code
to global Sms to number with country code
date global Current time in YYYY-MM-DD h:i:s format

Advanced output: Filters

Output markup can take filters, which modify the result of the output statement. You can invoke filters by following the output statement’s main expression with:

  • A pipe character (|)
  • The name of the filter
  • Optionally, a colon (:) and a comma-separated list of additional parameters to the filter. Each additional parameter must be a valid expression, and each filter pre-defines the parameters it accepts and the order in which they must be passed.

Filters can also be chained together by adding additional filter statements (starting with another pipe character). The output of the previous filter will be the input for the next one.

default returns the given variable unless it is null or the empty string, when it will return the given value, e.g {{ undefined_variable | default: "Default value" }} #=> "Default value"

Strings. Literal strings must be surrounded by double quotes or single quotes (“my string” or ‘my string’). There is no difference; neither style allows variable interpolation.

Integers. Integers must not be quoted.

Booleans and nil. The literal values true, false, and nil.

Other variable within variable

Sometimes you want to use the other variable value with in variable to get the right value

[] can used to pass the variable with in other variable. ex: {{questions.[jump].name}}

Here we are using jump variable to get the original value of question.
