API Keys - DualEntry Documentation

API keys are how every request to the DualEntry Public API authenticates. These pages cover the full lifecycle: issuing a key, sending it, and replacing it.

What this section covers

How to Give an Integration Access to DualEntry: issue a key with the right roles for the integration you’re building.
How to Authenticate Your Requests to the DualEntry API: send the X-API-KEY header and handle both 403 failure modes.
How to Replace an API Key: rotate a key without an authentication gap.

Where to go next
