This is a quick reference for bulk linking Infigo customers to a Connect integration user by setting the customer’s External ID during Customer CSV Import.
It applies to any Connect plugin that exposes a customer external reference field via the CSV Import page or when clicking the Connect Link button on a customer entry. Common examples include Connect: printIQ, Connect: Tharstern, Connect: CERM, and Connect: Veracore.


This does not bulk create customers in your MIS or other external system. It links customers across systems using the external identifier.

When to use this
Use this when you are implementing an MIS or integration alongside Infigo and you want to:
-
Bulk import customers into Infigo.
-
Bulk update existing Infigo customers.
-
Avoid opening each customer record just to press a Connect button, by supplying the external ID in the import instead.
Before you start
-
Ensure your Connect plugin is enabled and configured. Use the Academy setup guide for your plugin.
-
Gather the correct external identifier for each customer from the connected system. The exact value depends on the integration and the customer record structure in that system.
-
Keep imports manageable. We recommend 200 customers per CSV, then upload multiple files one after another if needed.
Step by step: bulk link customers to a Connect plugin via CSV Import
1) Download the Customer Template CSV
Go to Admin → Customers → Customer Management → CSV Import, then select Download Customer Template CSV.

2) Find the correct External ID column header for your Connect plugin
On the same CSV Import page, look for the info section that lists plugin link columns. It will show you the exact header text to use for each enabled Connect plugin.
Important notes:
-
The headings are case sensitive.
-
The value is usually not required, so you can include it only for customers you want to link.

3) Add a new column to your CSV using that exact header
Add a new column to the template CSV. The column header must match what the page shows for your plugin.
Example only: if you are using Connect: printIQ, the header shown is Mis.PrintIQ. Your environment may show different headers depending on which plugins are enabled.
Then populate each row with the customer’s external ID from the connected system.
4) Populate the rest of the customer rows as normal
Fill out the customer details you want to import or update. You do not need to fill every field. The importer validates the rows and reports any issues so you can fix and re upload.
For the full field list and import behaviour, use:
5) Upload the CSV and run the import
Upload your CSV in the CSV Import tab and run the import. Infigo will create or update the customers, and store the external ID values so the customers are linked to the relevant Connect integration without needing per customer manual linking.
