Payload field transformers
A very important feature in Lead Prosper is the ability to modify or transform the data passed by the suppliers before it's sent to the buyer.
This is needed in most multi buyer setups, where your supplier is passing data in a format that your buyer might not accept. Take for example a phone number. Your supplier might send it as 1 (313) 2492384. However, your buyer wants it as 3132492384. No spaces, no extra characters, no country code.
For this purpose, Lead Prosper created a couple of handy modifiers that you can use when building your payloads to help you transform the data.

How to use Field Transformers
To use any transformer on any dynamic field, all you need to do is add the  symbol inside the merge tag. Example: {{FieldTransformer:Parameter}}
Some transformers need parameters, like date, where you can pass the format in which you want to get the date. Consult the table bellow for all the available transformers and their parameters.
You can use more than 1 modifier for 1 string. Example: {{FieldTransformer1Transformer2Transformer3}} {{fieldreplace:Male@@Mreplace:Female@@F}}
Some transformers will need more than 1 parameter. Parameters are delimited by @@. Example: {{Fieldchars:0@@4}}.
Field transformers can be use in the following places:
 realtime and webhook payload builder, for both HTTP or Email delivery
 direct post and ping/post URLs
 direct post and ping/post headers
Practical Example
Let's assume we have the following multi buyer campaign:
Our supplier generates the following lead:
 first_name: David
 dob: 02/12/1967
 phone_number: 1 (619) 2674352
 income: $100,000
 email: david@company.com
Our buyer John would like to receive the first name in upper case, lead's age instead of dob and income as a number.
On the other hand, Jane would like to receive the first name lower case, email as md5 hash, and phone as a 10digit phone number.
To make this possible, we have to apply the following transformers to our campaign fields before we send the data to the buyer:
 to get the upper case name, we will use {{first_nameupper_case}}
 to get the lower case name, we will use {{first_namelower_case}}
 to get the age for John, we will use {{dobage}}
 to get the income as number, we will use {{incomenumber}}
 to get the md5 hash of the email, we will use {{emailencode:md5}}
 to get the phone as a 10 digit number, we will use {{phone_numberphone:10}}
Here is the final payload for John

# date
This method allows you to format a valid formatted date to another format. Check Appendix C for possible output formats.
 OUTPUT FORMAT
 Required. Valid date format
 SOURCE FORMAT
 Optional. The source format of the date value. IMPORTANT: This field is required when your date starts with the month (m/d/Y, mdY, etc) or the day (d/m/Y, dmY, etc). Consider this date: 04062023. The system can't correctly know if 04 is the month or the day.
Examples
Given your input is 2015/07/21
, applying date:Ymd\TH:i:s\Z
will transform it 20150721T00:00:00Z
Given your input is 20150721 01:23:45 PM
, applying date:Ymd H:i:s
will transform it 20150721 13:23:45
Given your input is 20200203 23:45:23
, applying date:Ymd h:i:s A
will transform it 20200203 11:45:23 PM
Given your input is 07232000
and your field date format is 01/15/2000
(m/d/Y), applying date:Ymd
will fail, because the date starts with a month. Applying date:Ymd@@m/d/Y
will transform the date to 20000723. Please make sure the SOURCE FORMAT matches your campaign field date format, otherwise the transformer will ignore the date.
# date_add
This method allows you to add an interval of time to a date.
 INTERVAL
 Required. Valid interval. Possible values are: Y, M, W, D, h, m, s
Important notes:
 The date might not start with the month. Please use the date transformer to format the date to a different format before applying date_add or date_sub transformers
 The output value will always be in this format: YMD H:M:S, regardless if the input date was just YMD or any other format. As such, it might be required that, after applying this transfomer, you will need to use the date transformer to correct the output.
 You can use any combination of the intervals, and omit the ones with 0. Ex: 1M 1m 10s will add 1month, 1minute and 10seconds. The only caveat is to not add the weeks before the month.
Examples
Given your input is 2015/07/21
, applying date_add:1Y 1M 1D
will transform it 20160822 00:00:00
Given your input is 20150721 01:23:45 PM
, applying date_add:3h 10m 15s
will transform it 20150721 04:34:00
# date_sub
This method allows you to subtract an interval of time from a date.
 INTERVAL
 Required. Valid interval. Possible values are: Y, M, W, D, h, m, s
Please check date_add transformer for more info.
# date_diff
This method allows you to calculate the difference between a given date and today's date
 INTERVAL
 Required, interval in which the diff is calculated. Possible values are: days, months, years
Important notes:
 The date might not start with the month. Please use the date transformer to format the date to a different format before applying this transformers
Combined with if_else_between transformer, you can easily transform a date to a text. Say we have the incident date and we need to send to our a buyer one of the following intervals: In the last month, More than a month ago, More than a year ago. To do so, we will apply the date_diff:months
transformer and combine it with if_else_between
to transform a number (the number of months since the incident) to the desired buyer interval.
Examples
Given your input is 2015/07/21
, applying  date_diff:months
will transform it 86
, assuming today's date is 20221010.
Given your input is 20150721 01:23:45 PM
, applying date_diff:years
will transform it 7
, assuming today's date is 20221010.
# timezone
This method allows you to convert the timezone for a date
 TIMEZONE
 Required.
Timezone abbreviation must be one of the timezones listed here.
This transformer should only be used for UTC dates or dates that contain the timezone in the string. By default, this will treat every date as UTC. This transformer is mostly used with our system field keys: lp_date and lp_timestamp.
# us_state and us_state_long
Transforms a matching US state string between full text or 2 letter abbreviation
Examples
Given your input is Florida
, applying us_state
will transform it to FL
Given your input is FL
, applying us_state_long
will transform it to Florida
# to_bool
Transforms 0 to 'false' and 1 to 'true'. Any other input will be ignored.
Examples
Given your input is 0
, applying to_bool
will transform it to false
Given your input is 1
, applying to_bool
will transform it to true
Given your input is test
, applying to_bool
will transform it to test
# from_bool
Transforms 'false' to 0 and 'true' to 1. Any other input will be ignored.
Examples
Given your input is false
, applying from_bool
will transform it to 0
Given your input is true
, applying from_bool
will transform it to 1
Given your input is test
, applying from_bool
will transform it to test
# if_else
Transforms values based on a configuration map and simple conditions. This is very useful on text fields that receive fixed values from suppliers, but have to be mapped to different buyer values.
The format of this transformer is: if_else:[FIND>REPLACE@@FIND>REPLACE@@fallback>REPLACE]. fallback
is optional. There is no limit on how many FIND>REPLACE keys you can add See examples bellow on how to use.
Important: this transformer works on full input values, not on parts of the value. The conditions are evaluated in order. If any of them matches, the others are ignored and the input value is replaced with the value of the condition. The optional fallback
condition can be added in case all if
conditions are not met. If fallback
and no conditions are met, the original input value will be preserved.
Examples
Let's consider we have a credit_score field that can receive the following values: 300600
, 600700
, 700900
Your buyer needs the credit_score as: poor
, fair
, good
To achieve that, we have to transform the field: {{credit_scoreif_else:[300600>poor@@600700>fair@@700900>good]}}
If the supplier sends the value 600700
, the following will happen: we will first try to match 300600
. Because that was a no match, we continue to the next condition, which is 600700
. Because this matches, we will replace the credit_score field to fair
If you want to replace all other values with "unknown", you will need to add the fallback
condition: {{credit_scoreif_else:[300600>poor@@600700>fair@@700900>good@@fallback>unknown]}}
# if_else_between
Transforms values based on a configuration map and a numeric value that is between a min and a max value. This is very useful on fields that receive a numeric value from suppliers, but have to be mapped to different buyer values depending on a value range.
The format of this transformer is: if_else_between:[MIN,MAX>REPLACE@@MIN,MAX>REPLACE@@fallback>REPLACE]. fallback
is optional. There is no limit on how many MIN,MAX>REPLACE keys you can add. See examples bellow on how to use.
Important: ensure the value of the field is numeric. Multiple formats are accepted, like: 1234; 1,234; 1,234.56. Any other format most likely will fail. The conditions are evaluated in order. If any of them matches, the others are ignored and the input value is replaced with the value of the condition. The optional fallback
condition can be added in case all if
conditions are not met. If fallback
and no conditions are met, the original input value will be preserved.
Examples
Let's consider we have a field that receives a number of miles a car is driven every year. Examples: 11,000
, 5000
However, your buyer needs to know an approximate range, like: 1000
, 5000
, 10000
, 15000
To achieve that, we have to transform the field: {{car_milesif_else_between:[0,1000>1000@@1001,5000>5000@@5001,10000>10000@@10000,over>15000@@fallback>10000]}}
In this example, if the supplier passes 7000
, the buyer will receive 10000. If the supplier passes 11256
, the buyer will receive 15000. If supplier does not send this field, because we use fallback
, buyer will receive 10000.
In the above example, we used 10000,over
. The reserved key over
can be used to define an unlimited max value for the range. This is the same as doing 10000,99999999999
# height
Transforms a given height (numeric value) into feet or inches.
 UNIT
 Required. Can be ft or in
Examples
Given your input is 67
, applying height:ft
will calculate the height in feet and return 5

, applying math_floor
will return 24
# math_modulo
This arithmetic operation calculates the remainder of a field value divided by the given argument. This function is very useful to convert height or months.
 NUMBER
 Required. Must be numeric and greater than 0
Examples
Given your input is 65
, applying math_modulo:12
will return 5
. Useful when you have the height in inches, and you need to extract the inches left after converting to ft/in.
Given your input is 26
, applying math_modulo:12
will return 2
. Useful when you have the total numbers of month left in a lease. and you need to calculate the months left without the matching years.
Important notes
 some characters will have to be converted when used as parameters for the modifier. Check Appendix A
 for the transformers that allow configuration, ensure that the following chars are not passed as a parameter:  and @@
 transformers with configuration errors, like invalid parameters or invalid modifiers, will be ignored. please run tests after adding a transformer to ensure your campaign can still receive and deliver the lead as you want.
Appendix A  special characters
Character  Replace with 
"  %22 
\  %5C

If you wish to use your own words (like on, at), those characters have to be escaped by the help of \. Some (\e, \f, \n, \r, \t, \v) must be doubleescaped (\\e, \\f, \\n, \\r, \\t, \\v). See last example in the table above.
