<Warning>
  **Deprecation Notice**

  All embedding features are being deprecated and will be removed from shortly.\
  We recommend that you do not build new integrations using this feature.

  **Recommended Alternative:** We recommend integrating Cekura into your platform via our [APIs](/api-reference). We also have an [MCP server](/mcp) to make it easier for you — simply ask Claude Code to use the Cekura MCP and get a UI quickly!

  If you have existing integrations using embedding, please plan to migrate to our APIs before the removal date.
</Warning>

## Overview

This documentation explains how to refresh expired tokens for your embedded Cekura agents to maintain uninterrupted service.

## Base URL

```
https://api.cekura.ai
```

## Authentication Endpoint

### Refresh Token

```
POST /user/v1/embedded/refresh/
```

This endpoint generates a new access token using your refresh token when the current access token expires.

### Request Headers

| Header       | Description      |
| ------------ | ---------------- |
| Content-Type | application/json |

### Request Body

```json theme={null}
{
    "refresh": "YOUR_REFRESH_TOKEN"
}
```

#### Parameters

* `refresh` (string, required): Your valid refresh token obtained from the initial token generation

### Response

A successful request will return a new access token for continued agent embedding.

#### Success Response Example

```json theme={null}
{
    "access": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
}
```

#### Response Fields

* `access` (string): New JWT access token for embedding the agent

### Error Responses

| Status Code | Description                      |
| ----------- | -------------------------------- |
| 400         | Invalid request parameters       |
| 401         | Invalid or expired refresh token |
| 403         | Unauthorized access              |
| 500         | Internal server error            |

## Implementation Steps

1. Monitor your access token's expiration
2. Before the access token expires, use your refresh token to request a new one
3. Update your application with the new access token
4. Continue using the agent embed widget with the new token

## Token Lifecycle

* Access tokens expire after 24 hours (1 day)
* Refresh tokens have a longer lifetime than access tokens
* If the refresh token expires, you'll need to generate new tokens using the initial token generation endpoint
* Implement proper error handling for failed refresh attempts

## Security Considerations

* Store refresh tokens securely
* Use HTTPS for all API calls
* Implement proper error handling
* Clear all tokens when removing the agent embed
* Never expose tokens in client-side code
