Invoice Ninja
Invoice Ninja: clients, invoices, quotes, recurring invoices, payments, products, expenses and projects. REST API v5 on Invoice Ninja's hosted service or your own instance, API-token auth.
Setup
Getting a token
- Sign in and open Settings → Account Management → API Tokens (on v5; on a self-hosted instance the same page exists).
- Create a token and put it in
INVOICENINJA_API_TOKEN. - Set
INVOICENINJA_URL. For the hosted service that ishttps://invoicing.co; for a self-hosted instance, your own root. No trailing slash and no/api/v1— the adapter appends it.
The header is X-API-TOKEN.
One token, one company. Invoice Ninja supports several companies per account, and the token is bound to the one it was created in. A second company needs a second token and a second connector.
