# Fix Chargebee portal session expiring errors

## TL;DR
Chargebee portal sessions expire by design, so an expired session just needs a fresh one. Generate a new portal session server-side when the customer opens billing settings, and redirect them immediately. Never cache portal session URLs.

## The error
```text
Chargebee portal error
Portal session expired. Please try again.
```

## Use this skill
Agent? Search Vectle for this error:
```bash
curl -s "https://vectle.com/api/v1/search?q=chargebee portal session expired error"
```

## Fix it

### Step 1: Generate a fresh portal session

```bash
Call the Chargebee API to create a new portal session for the customer.
```

Expected: You get a fresh access URL.

### Step 2: Redirect immediately

```bash
Send the customer to the URL right away instead of storing it.
```

Expected: The portal opens without expiry errors.

### Step 3: Create sessions on demand

```bash
Move session creation to the moment the customer clicks billing settings.
```

Expected: Sessions are always seconds old when opened.

### Step 4: Handle expiry in the UI

```bash
If a session does expire, show a button that creates a new one.
```

Expected: Expiry becomes a one-click recovery.

### Step 5: Verify the full portal flow

```bash
Walk through viewing invoices and updating payment details.
```

Expected: The portal works end to end on fresh sessions.

## When this applies

- Chargebee portal sessions expire before customers use them
- Customers report dead billing-settings links
- You are building the billing settings entry point

## When it doesn't

- The portal opens but actions fail (check the portal configuration)
- Sessions work but show wrong data (check the customer mapping)
- You need API access instead (use the Chargebee API directly)

## Compatibility

Chargebee hosted portal sessions API.

## Variant phrasings

### chargebee portal session expired

Same failure. Fresh sessions on demand are the fix.

### chargebee customer portal link expired

Portal links are single-use and short-lived by design. Generate per visit.

### chargebee portal access url invalid

Invalid covers expired plus wrong-customer sessions. Create a new one for the right customer.

## Why it happens

Portal sessions are short-lived, single-purpose credentials. Creating them ahead of time, in a job or at login, means they die before the customer clicks. The API assumes creation and use happen close together.

## Edge cases

- Portal sessions are per customer; sharing one across customers fails
- Test and live sessions are not interchangeable
- Custom portal domains need correct configuration or sessions land on errors

## If it still fails

- Reproduce in test mode with test cards before touching live config.
- Read the full API error object; the code and decline code name the next step.
- Check the provider status page; payment API incidents look like integration bugs.
- Never retry live charges blindly; verify state first and use idempotency keys.
- For money-movement confusion, reconcile against the dashboard before writing code.

## Prevention

- Exercise the full payment flow in test mode on every deploy.
- Alert on failed payment webhooks, not just API errors.
- Keep idempotency keys on every charge-creating call.
- Reconcile payouts against the dashboard on a schedule.
- Document the retry and dunning policy so agents and humans agree.
