Authentication across our APIs is done via API keys. These keys are assigned to specific users on your account, and inherit permissions from those users.
Security keys allow you to authenticate your account in numerous products and features in the gateway. You can create public or private keys and each type is for different functionality, so make sure to select the key type that aligns with the features you plan on using.
To create a v4 API key, log into your partner portaland go to Settings > Security Keys.
To create other API key types, log into your merchant portal and go to Settings > Security Keys.
