Overview

The Macro Editor in Flowmage allows you to dynamically transform, manipulate, and generate data inside your flows.

Instead of using static values, you can:

• Modify text

• Work with dates

• Build logic

• Handle arrays

• Encode/decode data

• Perform calculations

? This makes your flows dynamic, reusable, and intelligent.

Where to Find It

You can open the Macro Editor by clicking the ƒ (function) icon next to any input field.

Inside nodes like:

• AI nodes (Claude, OpenAI)

• Integration nodes

• HTTP requests

• Conditions

• Variables

Basic Syntax

Macros are always wrapped like this:

[MACRO]function_name(parameters)[#MACRO]

Example

[MACRO]str_replace(Hoi, doei, Hoi hoe gaat het?)[#MACRO]

? Output:

doei hoe gaat het?

Using Variables

You can combine macros with Flowmage variables:

[MACRO]str_replace(Hoi, doei, @webhook.message@)[#MACRO]

? This lets you dynamically transform incoming data.

Live Preview

The Macro Editor includes a preview panel, so you can instantly see:

• Your input

• The macro result

⚠️ If you see undefined, it usually means:

• A variable is empty

• The variable does not exist yet

• The flow hasn’t run yet

? Macro Categories

All macros are grouped into categories:

• Date

• Random

• String

• Array

• Logic

• Encoding

• HTML

• Encryption

• JSON

• Math

? Date Macros

Used for working with dates and time.

date(format)

Format the current date.

[MACRO]date(Y-m-d)[#MACRO]

date_add(datetime, interval, format)

Add time.

[MACRO]date_add(@now@, 1 day, Y-m-d)[#MACRO]

date_sub(datetime, interval, format)

Subtract time.

date_diff(date1, date2, format)

Difference between two dates.

date_to_timestamp(date, format, lang, tz)

Convert to UNIX timestamp.

date_format(datetime, format, tz)

Change format of a date.

timestamp()

Current UNIX timestamp.

timestamp_to_date(ts, format)

Convert timestamp to readable date.

? Random Macros

Generate random values.

special_random(chars, len, type)

Generate random string.

random_int(min, max)

Random number.

[MACRO]random_int(1, 100)[#MACRO]

uuid()

Generate unique ID.

? String Macros

Most used category — manipulate text.

default(value, fallback)

Fallback if empty.

[MACRO]default(@name@, Unknown)[#MACRO]

concat(values...)

Join strings.

str_replace(search, replace, string)

Replace text.

substr(string, start, length)

Extract part of string.

strlen(string)

Character count.

reverse(value)

repeat(string, count)

Repeat text.

strtolower(string)

strtoupper(string)

Uppercase.

ucfirst(string)

Capitalize first letter.

ucwords(string, delimiter)

Capitalize words.

trim(string, chars)

Remove spaces or characters.

slugify(string)

Create URL-friendly string.

remove_break_lines(string)

Remove line breaks.

str_contains(string, needle)

Check if contains.

str_starts_with(string, needle)

Check prefix.

str_ends_with(string, needle)

Check suffix.

? Array Macros

Work with lists of data.

unique(values...)

Remove duplicates.

sort(values..., direction)

Sort array.

[MACRO]sort(3,1,2, asc)[#MACRO]

? Logic Macros

Used for conditions and comparisons.

equals(a, b)

Check equality.

not_equals(a, b)

gt(a, b)

Greater than.

gte(a, b)

lt(a, b)

lte(a, b)

? Perfect for use inside conditions or AI prompts.

? Encoding Macros

base64_encode(value)

base64_decode(string)

urlencode(string)

urldecode(string)

? HTML Macros

strip_tags(string)

Remove HTML.

? Encryption Macros

md5(string)

sha1(string)

crc32(string)

? JSON Macros

json_encode(value)

Convert object → JSON.

json_decode(string)

Parse JSON → object.

➗ Math Macros

sum(a, b)

subtract(a, b)

multiply(a, b)

division(a, b)

round(value, precision)

? Real-Life Examples

Clean incoming webhook text

[MACRO]trim(@webhook.message@)[#MACRO]

Generate username

[MACRO]slugify(@user.name@)[#MACRO]

Fallback value

[MACRO]default(@email@, no-email@company.com)[#MACRO]

Add 7 days to current date

[MACRO]date_add(@now@, 7 days, Y-m-d)[#MACRO]

Create unique ID

[MACRO]uuid()[#MACRO]

⚠️ Common Mistakes

❌ Undefined values

Preview shows undefined.

✅ Ensure variable exists or use default()

❌ Wrong syntax

❌ Missing [MACRO]
❌ Wrong parameter order

❌ Using macros outside supported fields

Not all fields support macros.

? Pro Tips

• Combine multiple macros for powerful transformations

• Always test with preview

• Use default() to prevent errors

• Keep macros readable (don’t over-nest)

• Use variables everywhere for dynamic flows

Summary

The Macro Editor is one of the most powerful features in Flowmage.

It allows you to:

• Transform data

• Add logic

• Generate values

• Build dynamic automations
