Likelihood to buy again

In this tutorial, we'll show you how to:

Create a predictive model for likelihood to buy again using an outcome.

Let's dive in.

You'll need a Faraday account — signup is free!

Cohorts

Unless you’ve already created them for another quickstart or purpose, you’ll need to add the following cohorts to your account:

Repeat purchasers
Customers

What’s a cohort?

A cohort is Faraday’s term for a commercially significant group of people — for example, a brand’s customers, leads, or even “people who bought X and Y and then cancelled.”

Cohort membership is fluid — continuously computed by Faraday — and is defined by events its members must all have experienced and/or traits its members must all share.

For example, a Customers cohort could be defined as the group of people who have all experienced a Transaction event at least once.

For more, see our docs on Cohorts, Events, Traits, and Datasets (which define how events and traits emerge from your data).

curl

To verify, use a GET /cohorts request. Your response should look like this:

[{
  "name": "Repeat purchasers",
  "id": "$REPEAT_PURCHASERS_COHORT_ID"
, ...}{
  "name": "Customers",
  "id": "$CUSTOMERS_COHORT_ID"
, ...}]

Make note of the IDs of the necessary cohorts.

If the required cohorts aren’t there, follow the instructions using these buttons, then return here to resume.

Create a likelihood to buy again outcome

curl

Use a POST /outcomes request:

curl https://api.faraday.ai/outcomes --json '{
  "name": "Likelihood to buy again",
  "attainment": "$REPEAT_PURCHASERS_COHORT_ID",
  "eligible": "$CUSTOMERS_COHORT_ID"
}'

Your outcome will start building in the background. You can proceed immediately with the next set of instructions. When your outcome is done building, you’ll get an email.
