# BillDesk
> Add BillDesk as a payment provider on Optimizer.
Available in
🇮🇳 India
Follow the steps below to onboard BillDesk as a payment provider.
1. Write to your BillDesk Relationship Manager with the following requests:
* Enable seamless/S2S mode for your account. Mention that you use Razorpay as the technology company to handle sensitive card data.
* Enable `cards`, `upi` and `netbanking` methods.
* Configure the common BillDesk certificate used by Optimizer merchants.
* Configure the following webhook:
| Type | URL |
| ------------------ | --------------------------------------------------------- |
| **Production URL** | `https://api.razorpay.com/v1/callback/billdesk_optimizer` |
* Enable the following if you intend to use UPI.
* Whitelist the following IPs to make the API calls (Initiate Transaction, Authorization API call, Verify Transaction, Refund Initiation, Verify Refund):
* 52.66.75.174
* 52.66.76.63
* 52.66.151.218
* 35.154.217.40
* 35.154.22.73
* 35.154.143.15
* 13.126.199.247
* 13.126.238.192
* 13.232.194.134
**Handy Tips**
You should share the above mentioned IPs with BillDesk for whitelisting.
* Provide configuration details like a checksum algorithm for stage and production, BankID and card network list.
2. BillDesk S2S card integration supports two features:
* **Regular card processing**
* **NoRedirect based Payment**
You should configure **Regular card processing** at the BillDesk side, not **NoRedirect based Payment**.
3. To pass your unique **Order ID** or **Receipt** for every order, write to your Relationship Manager to show the `additional_info1` parameter in BillDesk Dashboard and customised report. Know more about [how to send your order id to BillDesk](#send-receipt-order-id-to-external-gateway).
**Watch Out!**
While Optimizer can route payments based on your business logic, the method enablement of each gateway needs to be handled between you and the gateway, or it may lead to failed payments.
## Add BillDesk as a Payment Provider
1. Log in to your Dashboard.
2. Go to the **PAYMENT PRODUCTS** section and click **Optimizer**.
3. In the top right section, click **+ Add provider**.
4. Select **BillDesk** in the list of gateways available and click **Next**.
5. Enter the provider name and description and click **Next**.
6. Enter your Client ID and Merchant ID.
7. Select the payment methods you want to enable for BillDesk and click **Submit**.
You have successfully added **BillDesk** as a payment provider on Optimizer.
## Supported Payment Methods
| Payment Methods | Availability |
| --------------- | ------------ |
| Netbanking | Live |
| Cards | Live |
| UPI | Live |
| Wallet | Live |
**Handy Tips**
Billdesk supports [Third-Party Validation (TPV)](/docs/payments/optimizer/third-party-validation#supported-bank-gateways-payment-gateways-and-payment-methods).
## Send Receipt/Order ID to External Gateway
You might be generating a unique Order ID or Receipt for every order which can be passed to BillDesk via [Orders API](/docs/api/orders#orders-api).
Follow the steps given below for your order id to be visible on the BillDesk Dashboard:
1. In Razorpay's [Orders API](/docs/api/orders#orders-api), use the `receipt` parameter to send your unique Order ID or Receipt.
2. Razorpay passes this value to BillDesk in the `additional_info1` parameter.
3. Write to your BillDesk Relationship Manager to show the parameter `additional_info1` in the Dashboard and reports as per your use case.
## Best Practices
Before routing all traffic or some traffic to a new gateway via Optimizer, the following best practices are recommended:
All rules configured on live or test mode on the Razorpay Dashboard will reflect on live mode. However, credentials added on test mode will not be automatically replicated in live mode.
You can reach out to Razorpay for basic sanity testing of the integration. Razorpay will try a test payment of small value and ensure that the credentials are correct.
We recommend configuring a rule on live mode to route payments lesser than a set value (for example, ₹2) to the BillDesk gateway. This helps to test on production whether small value payments are being routed to BillDesk and working successfully, thus avoiding any direct impact on production traffic.
To configure a rule in live mode:
1. Log in to your Dashboard.
2. In the left navigation, click **Optimizer**.
3. Click **+Add Rule** and enter the **Rule name** and **Description**.
4. Click **Next** and enter the following rule:
* In **Parameter** field, select **Amount (In Rupees)**
* In **Select Connection** field, select **Less Than**
* In **Enter Amount** field, enter the value 2 and click **Next**.
5. Enter the value 100 in the **Route field**, select **billdesk\_optimizer** in the **payment via** field, and click **Next**.
6. Click **Publish Rule**.
## Go Live
After the integration is tested and successful, you can go live on BillDesk.
