Summary: Neon OAuth integration lets partner applications act on Neon user accounts without storing credentials, using an OpenID Connect server at oauth2.neon.tech with predefined project and organization scopes. Use this page when building a third-party integration that must read, create, update, or delete Neon projects and organizations on behalf of end users via the authorization code grant flow. Access is limited to active Neon commercial partners. The page covers the consent screen, authorization URL construction, code-for-token exchange, and refresh token scopes.

The Neon OAuth integration enables your application to interact with Neon user accounts, carrying out permitted actions on their behalf. Our integration does not require direct access to user login credentials and is conducted with their approval, ensuring data privacy and security.

Note: We only provide OAuth integrations for partners we have active commercial relationships with. If you already partner with Neon, the information below documents our OAuth integration. Reach out to your Neon point of contact if you have any questions.

Here is a high-level overview of how Neon's OAuth implementation works:

1. The user sends a request to your API endpoint to initiate the OAuth flow by clicking a button or link in your application.
2. An authorization URL is generated.
3. The user is redirected to Neon's OAuth consent screen to authorize the application.
4. The user logs in and authorizes the application, granting it the necessary permissions.
5. The user is redirected to your callback endpoint with an access token that allows the application to manage Neon resources on the user's behalf.

The Neon OAuth server implements the OpenID Connect protocol and supports OpenID Connect Discovery specification. The server metadata is published at the following well-known URL: https://oauth2.neon.tech/.well-known/openid-configuration.

Here is an example response:

}

Note: You must add offline and offline_access scopes to your request to receive the refresh_token.

Depending on the OpenID client you're using, you might not need to explicitly interact with the API endpoints listed below. OAuth 2.0 clients typically handle this interaction automatically. For example, the Neon CLI, written in Typescript, interacts with the API endpoints automatically to retrieve the refresh_token and access_token. Here's a simplified example of how the Neon CLI performs the token exchange using the openid-client library:

const configuration = await client.discovery(
  new URL(oauthHost),
  clientId,
  { token_endpoint_auth_method: 'none' },
  client.None()
);

// After the user authenticates in the browser, the CLI's local
// callback server receives the redirect as `request`. The full
// callback URL is built from that request plus the server's own
// port (`listen_port`):
const tokenSet = await client.authorizationCodeGrant(
  configuration,
  new URL(request.url, `http://127.0.0.1:${listen_port}`),
  {
    pkceCodeVerifier: codeVerifier,
    expectedState: state,
  }
);
// tokenSet.access_token and tokenSet.refresh_token are now available

In this example, the oauthHost is https://oauth2.neon.tech.

The following OAuth scopes allow varying degrees of access to Neon resources:

You must choose from these predefined scopes when requesting access; custom scopes are not supported.

Let's now go through the full flow, step by step:

To initiate the OAuth flow, you need to generate an authorization URL. You can do that by directing your users to https://oauth2.neon.tech/oauth2/auth while passing the following query parameters:

• client_id: your OAuth application's ID (provided by Neon when your OAuth application is registered)

• redirect_uri: the full URL that Neon should redirect users to after authorizing your application. The URL should match at least one of the callback URLs you provided when setting up your OAuth application.

• scope: This is a space-separated list of predefined scopes that define the level of access you want to request. For a full list of supported scopes and their meanings, see the Supported OAuth Scopes section.

  Example:

  urn:neoncloud:projects:create urn:neoncloud:projects:read urn:neoncloud:projects:update urn:neoncloud:projects:delete urn:neoncloud:orgs:read

• response_type: This should be set to code to indicate that you are using the Authorization Code grant type.

• code_challenge: This is a random string that is used to verify the integrity of the authorization code.

• state: This is a random string that is returned to your callback URL. You can use this parameter to verify that the request came from your application and not from a third party.

Here is an example of what the authorization URL might look like:

https://oauth2.neon.tech/oauth2/auth?client_id=neon-experimental&scope=openid%20offline%20offline_access%20urn%3Aneoncloud%3Aprojects%3Acreate%20urn%3Aneoncloud%3Aprojects%3Aread%20urn%3Aneoncloud%3Aprojects%3Aupdate%20urn%3Aneoncloud%3Aprojects%3Adelete&response_type=code&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fapi%2Fauth%2Fcallback%2Fneon&grant_type=authorization_code&state=H58y-rSTebc3QmNbRjNTX9dL73-IyoU2T_WNievO9as&code_challenge=99XcbwOFU6iEsvXr77Xxwsk9I0GL4c4c4Q8yPIVrF_0&code_challenge_method=S256

After being redirected to the authorization URL, the user is presented with Neon's OAuth consent screen, which is pre-populated with the scopes you requested. From the consent screen, the user is able to review the scopes and authorize the application to connect their Neon account.

Note: The Neon API provides a Get current user details endpoint for retrieving information about the currently authorized Neon user.

After successfully completing the authorization flow, the user is redirected to the callback URL with the following query parameters appended to the URL:

• code: an authorization code that will be exchanged for an access token
• scope: the scopes that the user authorized your application to access
• state: you can compare the value of this parameter with the original state you provided in the previous step to ensure that the request came from your application and not from a third party

You can now exchange the authorization code returned from the previous step for an access token. To do that, you need to send a POST request to https://oauth2.neon.tech/oauth2/token with the following parameters:

• client_id: your OAuth application's ID.
• redirect_uri: the full URL that Neon should redirect users to after authorizing your application. The URL should match at least one of the callback URLs you provided when setting up your OAuth application.
• client_secret: your OAuth application's secret
• grant_type: set this to authorization_code to indicate that you are using the Authorization Code grant type
• code: the authorization code returned from the previous step

The response object includes an access_token value, required for making requests to the Neon API on your users' behalf. This value must be supplied in the Authorization header of the HTTP request when sending requests to the Neon API.
