Overview
The purpose of this workflow is to capture leads from a CSV file and use these to create and update users in Iterable.
This workflow is fired every time a CSV file is uploaded onto a Tray Form:

Prerequisites
To implement this workflow, you will need the following:
- API credentials for Iterable
- A CSV file with the correct column setup. You can use this template to set up your CSV file.
Getting Live
Click 'Use Template' to deploy the template in your chosen Workspace. Then take the following steps to configure the workflow and start submitting leads for processing:
The workflow will then start the process of pulling the leads into Iterable.
End Result

Key workflow steps
The following diagram gives a simplified breakdown of the key steps in the workflow:

Standardization
This Object Helpers step transforms the CSV column headers into a standard object with fields in the following format:
First Name --> first_name
Last Name --> last_name
Lead Source --> lead_source
etc.
For each lead we will then have a simple object which can be easily accessed by later Iterable steps using jsonpaths such as $.steps.object-helpers-1.result.first_name:

Email validation
The lead’s email address is validated for the appropriate user@domain.com format:
Create / Update Users
A search is made for an existing contact in Iterable using the lead’s email address as the unique identifier.
If a Iterable user does exist, the user record is updated.
If a Iterable user does not exist, a new user record is created.
