API Authentication

Our range of data validation APIs can be authenticated using three different types of credentials depending on your use case.

For confidential, server-side applications you can choose either API keys or username & password authentication. API key authentication is normally preferred to avoid issues when you change the password on your account, and gives options to limit access only to the IP addresses and services used by each individual application.

For public-facing web applications you can choose either API keys or JWT authentication. API keys give a simpler implementation, but JWT allows your server full control over how many credits each of your users is allowed to consume.
