This guide outlines the process of configuring your API to use Ouro as an authentication and monetization middleman. By integrating Ouro, you can streamline several critical aspects of API management:
- Simplified authentication: Ouro handles user authentication, reducing the complexity of implementing and maintaining your own auth system.
- Monetization made easy: Ouro provides built-in tools for setting up paid routes, usage limits, and billing, allowing you to monetize your API without building a custom billing system.
- Rate limiting: By using Ouro as a proxy, you add an extra layer of security between your API and end-users.
- Usage analytics: Get insights into how your API is being used.
We've designed this process so that your end users will need to make minimal changes to their existing configuration:
- A new base URL to use
- An API key to pass with requests as an Auth header
Everything else, including parameter and request body configuration will be exactly the same as you originally designed it.
1. Getting started
To start using Ouro as your API middleman, you'll need to sign up for an Ouro account if you haven't already.
Next, you'll need to modify your API to work with Ouro. Your API will need to verify that incoming requests are coming from Ouro and to only respond to those requests.
Finally, you'll need to add your service to Ouro and configure any desired pricing and usage limits.
