# Pre-integration checklist

Before starting your integration with Xendit, ensure you’ve completed the following steps to avoid issues during testing or deployment.

## 1. Activate your payment channels

**Test Mode**

- All payment channels are available by default in test mode.
- However, some payment flows may be limited due to restrictions from partners (e.g., KYC requirements, regional constraints).
- If you encounter issues while testing, please contact our Customer Success team for assistance.

**Live Mode**

- Before going live, check that your desired payment channels are **activated** in the [Dashboard > Payment Channels](https://dashboard.xendit.co/payment-channels).
- If a payment channel is not activated, related API requests or payment links will fail in production.

## 2. Create a secret API key

Generate your API key from the Dashboard: **Settings > Developers > API Keys**

You can create different API keys for each environment or use case.

| Environment | Use case |
| --- | --- |
| **Test Mode** | for development and UAT testing. |
| **Live Mode** | for handling real transactions in production. |

**Best Practices**

- Set `Write` permissions if you’re using money-in features.
- Restrict your API key’s permissions to the minimum needed for its purpose.
- Store API keys securely using a secrets management tool.
- For more details, refer to our [API Key Guide](https://docs.xendit.co/xenplatform/settings/#api-key).

## 3. Set up your webhooks

To ensure your system receives real-time updates, **webhooks must be configured**, even if you use synchronous payment flows.

Why webhooks matter:

- They notify your system when a payment is completed (e.g., after 3DS or redirection flows).
- They help detect and reconcile late or previously unreported payments.

**How to register webhook endpoints:**

1. Go to [Settings > Webhooks in your Xendit Dashboard](https://dashboard.xendit.co/settings/developers#webhooks)
2. Enter your webhook **endpoint URLs**

3. Click **Test & Save** to verify delivery
4. Confirm that your system receives the exact test notification payload
