Why does this setting keep rotating the access token? I’m trying to bake an API token into a Deno Deploy environment variable for our CI/CD pipeline, but the token expires every 3600 seconds despite setting expires_in to 86400 in the /api/v2/oauth/token request. Using client credentials grant.
Thanks.
This looks like a misunderstanding of how client credentials grants handle expiration in Genesys Cloud. The expires_in parameter is strictly informational; it does not extend the validity period. The token will always expire after one hour regardless of the value sent. For CI/CD pipelines or server-to-server integrations like my PagerDuty webhook handler, you cannot rely on long-lived tokens. You must implement a token refresh logic. The Python SDK handles this automatically, but in Deno, you need to manage the lifecycle. Fetch a new token using the client ID and secret every 50 minutes. Store the token in a secure secret manager, not a hardcoded environment variable. Check the OAuth Documentation for the exact grant flow. Here is a basic Deno fetch example to rotate the token:
const tokenResponse = await fetch("https://api.mypurecloud.com/api/v2/oauth/token", {
method: "POST",
headers: { "Content-Type": "application/x-www-form-urlencoded" },
body: new URLSearchParams({
grant_type: "client_credentials",
client_id: Deno.env.get("GC_CLIENT_ID"),
client_secret: Deno.env.get("GC_CLIENT_SECRET")
})
});
const { access_token } = await tokenResponse.json();
Use this pattern to ensure your API calls never hit a 401 Unauthorized due to expiration.
The problem here is the client credentials flow does not support expires_in overrides. You must implement a rotation mechanism. I use a Deno cron job to fetch new tokens before expiry. See the official guide for token lifecycle management: https://developer.genesys.cloud/rest-api-v2/oauth/token
const res = await fetch('https://api.mypurecloud.com/api/v2/oauth/token', opts);Have you tried caching the token in a persistent storage layer instead of relying on a single Deno Deploy environment variable? The /api/v2/oauth/token endpoint strictly returns a 3600-second TTL for client credentials grants. The expires_in parameter is metadata, not a configuration switch. Baking a static token into your build pipeline is a security risk and a functional failure point.
You need a sidecar or a cron job to handle rotation. Use PureCloudPlatformClientV2 to manage the lifecycle. If you are using Deno, implement a simple retry loop with exponential backoff for the WebSocket connection.
const client = new PlatformClientV2();
await client.loginClientCredentials({
clientId: Deno.env.get("GENESYS_CLIENT_ID"),
clientSecret: Deno.env.get("GENESYS_SECRET")
});
// Token is cached internally. Do not store it in ENV.
Check the authorization header expiration before each request. If you ignore the 1-hour limit, your CI/CD pipeline will fail silently after the first hour. Implement a refresh hook.
It depends, but generally… hardcoding tokens in Deno Deploy env vars is a state management anti-pattern. You are fighting the OAuth spec, not Genesys Cloud. The expires_in field in the response is read-only metadata for the client credentials grant. It is always 3600s. You cannot override it.
If you are managing infrastructure via Terraform CX as Code, your CI/CD pipeline should not hold secrets. It should orchestrate the secret retrieval. The risk here is not just expiry, but secret rotation drift. If your Terraform state drifts from the actual Genesys Cloud org configuration, your pipeline breaks silently until the token expires.
Stop trying to extend the token. Implement a fetcher. In your Deno Deploy module, fetch the token on-demand or cache it in a KV store with a TTL of 3500s. This aligns with GitOps principles: infrastructure is defined, secrets are fetched, state is transient.
const GC_URL = "https://api.mypurecloud.com";
const CLIENT_ID = Deno.env.get("GC_CLIENT_ID");
const CLIENT_SECRET = Deno.env.get("GC_CLIENT_SECRET");
async function getAuthToken(): Promise<string> {
const res = await fetch(`${GC_URL}/api/v2/oauth/token`, {
method: "POST",
headers: {
"Content-Type": "application/json",
"Authorization": `Basic ${btoa(`${CLIENT_ID}:${CLIENT_SECRET}`)}`
},
body: JSON.stringify({
grant_type: "client_credentials"
})
});
if (!res.ok) throw new Error(`Auth failed: ${res.status}`);
const data = await res.json();
return data.access_token;
}
// Usage in your pipeline
const token = await getAuthToken();
const apiRes = await fetch(`${GC_URL}/api/v2/organizations`, {
headers: { "Authorization": `Bearer ${token}` }
});

Do not bake secrets. Fetch them. Keep your Terraform state clean and your pipelines secure.
