Invoice Ninja Client Reader

Read up to 50 clients from an Invoice Ninja v5 instance, including their contact and account properties.

Setup

Select your Invoice Ninja account in Read first 50 Invoice Ninja clients and allow invoice_ninja.list_clients. Configure the v5 instance URL and API token in the connection. Your account needs permission to view clients. For hosted v5, the instance URL is https://invoicing.co; use your own HTTPS instance root for a self-hosted installation. The connection accepts the origin or its /api/v1 URL; it does not support an installation under another path.

In n8n, select Invoice Ninja credentials in Invoice Ninja. Keep API Version set to Version 5 and use a v5 API token. The optional credential secret can remain empty for this client read; Invoice Ninja uses that secret on its login route. Run manually. Both formats target v5; they do not connect to a v4 deployment.

Each run reads the first page of up to 50 clients, without search, ordering or related-resource filters. It retains the complete v5 client objects returned by the server. Open Flow also returns pagination metadata. An empty account returns an empty clients array. The workflow does not collect every page, create invoices or modify clients. A failed request stops the run without an automatic retry.

Changes to the source

• Update the source’s v4 default to an explicit v5 configuration in both formats. v5 uses its current client response structure and hashed IDs; these records differ from v4 responses.
• Keep the source’s first-page, 50-client limit.
• Expose clients and pagination metadata in Open Flow.

Adapted from Invoice Ninja client list workflow in Zie619/n8n-workflows. The source export does not identify a separate template author or license.

The collection’s MIT notice is pinned at a later revision. This is the collection notice at that revision; it does not establish a separate original template author’s license. Our changes are listed above; see repository licensing.
