Many organizations rely on APIs to enable this connectivity. However, integrating these services can sometimes present challenges. One such challenge that has come up recently involves integrating Palantir Foundry with the company’s central API gateway through OAuth2. The Problem: OAuth2 Without an Auth Token You may find yourself in a scenario where: You want to integrate Foundry with your organization's API gateway. The API gateway requires OAuth2 authentication but only supports the Client Credential Flow. This flow does not utilize an Authorization Token, which is typically used in standard OAuth2 procedures. This can lead to confusion and frustration, especially if you are not aware of the available options to resolve this limitation. Understanding the OAuth2 Flows Before diving into the solution, it’s vital to understand the difference between OAuth2 flows relevant to our discussion: 1. Authorization Code Flow Use Case: Typically used for applications that can obtain an authorization code on behalf of a user. Authorization Token: Required to delegate access to resources after a user’s consent. 2. Client Credentials Flow Use Case: Designed for server-to-server interactions, where user interaction is not required. Authorization Token: Not used in this flow; instead, an Access Token is issued directly to the service account. The Solution: Leveraging Foundry's OAuth2 Support Palantir Foundry primarily supports OAuth2 through the Authorization Code Grant. However, the good news is: Support for the Client Credentials Grant is currently under limited release for a select group of customers. A general release is anticipated, with updates expected early this spring. Here are some steps to consider if you're facing this situation: 1. Check Your Current Setup Verify if the Client Credentials Grant is already available for your Foundry instance. You may need to work within your organization’s internal support channels to find out more. 2. Engage with Support Resources If the Client Credentials Grant is not available yet, reach out to your internal support team or Palantir’s customer support. Inquire about timelines for broader availability and express your needs clearly; this feedback can help prioritize your request. 3. Plan for Future Integration Keep an eye on updates from Foundry regarding the general release of Client Credentials support. Preparing for this integration involves ensuring your application code is ready to handle Access Tokens without needing authorization tokens. Conclusion Integrating Palantir Foundry with your company’s API gateway need not be a daunting task. By understanding the OAuth2 flows and the specific needs of your integration, you can navigate the complexities with ease. Remember to utilize your internal resources to stay ahead in this process. Soon, the Client Credentials Grant might just be the game-changer you need to complete your integration smoothly, enhancing productivity and operational synergy.
