POST /api/v2/oauth/clientcredentials
401 Unauthorized
I’ve got a Terraform module managing our Genesys Cloud OAuth credentials. The goal is to rotate the client_secret every 90 days without breaking the active API tokens. The docs mention creating a new secret and revoking the old one, but the provider doesn’t seem to handle the async revocation gracefully. It tries to delete the old secret before the new one is fully active. Anyone got a working genesyscloud_oauth_client config for zero-downtime rotation?
The issue is that Terraform wants a clean state swap, but Genesys Cloud keeps the old secret valid for a short window after you add a new one. You can’t just delete the old one immediately in the same apply cycle if your apps are still hitting the endpoint.
Here’s how I handled it in C#. The trick is to treat the secrets as a list, not a single value. You add the new secret first, wait for propagation, then remove the old one. The API docs say: “A client can have multiple active secrets. All active secrets are valid for authentication.”
// 1. Fetch current client config
var oauthApi = new OAuthApi(platformClient);
var client = await oauthApi.PostOauthClientAsync(environmentId, new PostOauthClientRequestBody
{
Name = "MyApp",
Scopes = new List<string> { "admin:agent", "admin:user" },
Secrets = new List<ClientSecret>
{
new ClientSecret { Secret = "OLD_SECRET_VALUE" } // Keep this active
}
});
// 2. Add the new secret to the list
var newSecret = "NEW_ROTATED_SECRET";
client.Secrets.Add(new ClientSecret { Secret = newSecret });
// 3. Update the client (this makes both secrets valid)
await oauthApi.PutOauthClientAsync(environmentId, client.Id, client);
// 4. Wait a bit. 5 seconds is usually enough for Genesys to propagate.
await Task.Delay(5000);
// 5. Remove the old secret
client.Secrets = client.Secrets.Where(s => s.Secret != "OLD_SECRET_VALUE").ToList();
await oauthApi.PutOauthClientAsync(environmentId, client.Id, client);
If you’re stuck with Terraform and can’t run this script, you might need to use a local-exec provisioner to call the API directly after the resource is created, but that’s messy. Better to manage the rotation in code than in IaC if you want zero downtime. The Retry-After header on 429s is a different beast, but for secrets, the race condition is purely about when the old one stops working.
That approach from is spot on, but you’ll want to be careful with the timing in Terraform. The Genesys Cloud API allows multiple secrets, yes, but the state file can get confused if you’re not explicit about which one is “old” versus “new”.
In my devops setup, I handle this by using a local variable to track the previous secret and only removing it after a short delay. You don’t need to rewrite the whole module. Just add a depends_on or a null_resource with a sleep command if you’re using the older provider versions. The key is ensuring the new secret is fully propagated before you revoke the old one.
Here is how I structure the rotation in my Terraform config. It creates the new secret, waits, then removes the old one from the list.
resource "genesyscloud_oauth_client" "api_client" {
name = "MyRotatingClient"
# Add the new secret to the list
secrets = [
var.new_client_secret,
var.old_client_secret # Keep this until propagation is confirmed
]
# Use a local exec provisioner or a null_resource to handle the delay if needed
lifecycle {
ignore_changes = [secrets] # Prevents TF from forcing a full replace on every plan
}
}
# Example of a null_resource to handle the async revocation
resource "null_resource" "rotate_secret" {
triggers = {
new_secret = var.new_client_secret
}
provisioner "local-exec" {
command = "sleep 30 && curl -X DELETE ${genesyscloud_oauth_client.api_client.secrets[1]} ... "
}
}
The ignore_changes on secrets is crucial. It stops Terraform from trying to manage the secret list directly during normal plans, letting your rotation script handle the actual API calls. You’ll still need to handle the HTTP calls for the actual revocation outside of the main resource block, usually via a local-exec or a separate CI/CD step. Don’t forget to update your application configs to pick up the new secret from the vault or secret manager. The API response will give you the new secret ID, so save that in state.
