Value-based lookalikes are an enhancement of Lookalike Audiences. With it you can include an arbitrary, numeric value for each user set when you create a seed custom audience from CRM data. Facebook uses this to determine which users in an audience are worth the most to you, in a quantifiable way.
To use this product, you must agree with the value-based lookalike terms of services for every ad account using this feature. See Terms of Service.
This is a specialized multi-key custom audience, you create with the parameter is_value_based
.
curl -X POST \
-F 'name="Value-Based Custom Audience"' \
-F 'subtype="CUSTOM"' \
-F 'is_value_based=1' \
-F 'customer_file_source="PARTNER_PROVIDED_ONLY"' \
-F 'access_token=<ACCESS_TOKEN>' \

You need to populate the new audience with supported identifiers and with the schema key LOOKALIKE_VALUE
. You can represent lookalike values by either an integer or float-point arbitrary non-negative number.
curl -X POST \
-F 'payload={
"schema": [
"EMAIL",
"LOOKALIKE_VALUE"
],
"data": [
[
"9b431636bd164765d63c573c346708846af4f68fe3701a77a3bdd7e7e5166254",

}' \

After the custom audience contains at least 100 people, you can use it as a seed audience for a new lookalike of type custom_ratio
.
curl -X POST \
-F 'name="Value-Based lookalike"' \
-F 'subtype="LOOKALIKE"' \
-F 'origin_audience_id="<CUSTOM_AUDIENCE_ID>"' \
-F 'lookalike_spec={
"type": "custom_ratio",
"ratio": 0.01,
"country": "US"
}' \
-F 'access_token=<ACCESS_TOKEN>' \
