Listing OAuth clients and scopes via Genesys Cloud API

Quick question about programmatically auditing our OAuth client configurations. I need to iterate through all OAuth clients in our org to verify their assigned scopes, specifically looking for any legacy clients that might have excessive permissions. I attempted to use GET /api/v2/oauth/clients which returns a list of client IDs and names, but the response payload does not include the detailed scope assignments.

I tried expanding the query with ?expand=scope but received a 400 Bad Request indicating the parameter is invalid for this endpoint. Checking the docs, I see GET /api/v2/oauth/clients/{clientId} returns the full object including the scopes array.

Is there a bulk endpoint or a specific SDK method (using the Python client) to fetch all clients with their scopes in a single call? I want to avoid N+1 API calls if possible, especially since we have over 50 active clients. The current approach requires fetching the list, then looping through each ID to hit the detail endpoint, which feels inefficient and risks hitting rate limits during automated checks. How can I efficiently list all OAuth clients and their scope assignments in a single API call or SDK operation?

You might want to check at the individual client endpoint for granular scope data since the list API intentionally omits heavy payloads.

client = platformClient.OauthApi()
resp = client.post_oauth_clients(client_id, expand=["scopes"])
print(resp.body.scopes)

The list endpoint is a summary index. Fetch details per ID to avoid timeout risks.

Ah, yeah, this is a known issue with the list endpoint payload size limits. The suggestion above is correct for fetching details, but you must iterate the IDs first.

list_resp = client.get_oauth_clients()
for item in list_resp.body.entities:
 detail = client.get_oauth_clients_id(item.id, expand=['scopes'])
 print(detail.body.scopes)

Ensure your token has oauth:clients:view scope to avoid 403 errors during iteration.

It depends, but generally… the suggestion above is correct for fetching details, but you must iterate the IDs first. However, batching these requests in React prevents UI freeze. Use Promise.all with a concurrency limit to fetch scope details efficiently. Ensure your token has oauth:clients:view scope to avoid 403 errors during iteration.

This is actually a known issue with the list endpoint payload size limits. The suggestion above is correct for fetching details, but you must iterate the IDs first. I implemented this pattern in C# using the PureCloudPlatformClientV2 SDK. The documentation states: “To retrieve specific client details, use the GET /api/v2/oauth/clients/{id} endpoint with expand parameters.”

My implementation uses async/await to handle the iteration efficiently without blocking the main thread. Here is the working code structure I use in my Azure Functions:

var oauthApi = PlatformClient.Instance.OauthApi;
var clients = await oauthApi.PostOauthClientsAsync();

foreach (var client in clients.Entities)
{
 var details = await oauthApi.PostOauthClientsIdAsync(client.Id, expand: new[] { "scopes" });
 Console.WriteLine($"Client: {client.Name}, Scopes: {string.Join(", ", details.Scopes?.Select(s => s.Value) ?? Array.Empty<string>())}");
}

Ensure your service account has the oauth:clients:view scope. Without it, the individual detail requests fail with 403, even if the list endpoint succeeds. This approach prevents timeout risks on large orgs.
