Get Started

Authentication

Each request to the Single-Invoice.co REST API must be submitted over HTTPS. The majority of the requests will require a valid API key (the exceptions are methods like Register and Login which have their own separate requirements).

There are currently two types of API keys - API Account Management Keys and Application Keys.

API Account Management Keys

Your API Account Management Key is created once your account has been approved. It provides access to the Account management functions; it should be used when you are performing actions like updating your account information or creating new API keys.

Coverage API Keys

Coverage API Keys are used for the majority of core methods - for example, looking up a company, getting a quote, or requesting coverage.
