What is an API?

An API — Application Programming Interface — is the contract that lets two software systems exchange information programmatically over a network. CorpNet's APIs let your application submit business-formation orders, retrieve their status, register employers for state and federal taxes, and manage ongoing entity compliance — without any human handoff in between.

If your team is new to working with REST APIs, the basics:

• You authenticate by attaching an API key to every request. CorpNet uses Bearer-token authentication — see Authorization.
• You exchange data over HTTPS using standard methods (GET to retrieve, POST to create, PATCH to update).
• Requests and responses are JSON.

Once authenticated, your application can trigger filings, polls, and document workflows automatically — replacing manual email or web-portal processes with a programmatic interface that scales.
