# 1. Create the Authorisation Transaction

> **WARN**

**UPI Collect Flow Deprecated**

According to NPCI guidelines, the UPI Collect flow is being deprecated for new UPI Autopay registrations effective 28 February 2026.

* Customers can no longer register UPI mandates by manually entering VPA/UPI id/mobile numbers.
* Subsequent debits for existing mandates created via UPI Collect will continue to be executed without change.

**Exemptions:**

UPI Collect will continue to be supported for:

* MCC 6012 & 6211 (IPO and secondary market transactions).
* iOS mobile app and mobile web transactions.
* UPI Mandates (execute/modify/revoke operations only).
* eRupi vouchers.
* PACB businesses (cross-border/international payments).

**Action Required:**

* If you are a new Razorpay user, use UPI Intent.
* If you are an existing Razorpay user not covered by exemptions, you must remove the UPI Collect parameters from `razorpay.js` and migrate to UPI Intent or UPI QR code to continue accepting UPI Autopay registrations. For detailed migration steps, refer to the [migration documentation](/announcements/upi-collect-migration/recurring-payments/custom-checkout).

You can create an authorisation transaction using [Razorpay APIs](#11-using-razorpay-apis) or [Registration Link](#12-using-a-registration-link).

## 1.1 Using Razorpay APIs

To create an authorisation transaction using Razorpay APIs, you need to:

<Steps>
  <Step title="[Create a Customer](#111-create-a-customer).">
    [Create a Customer](#111-create-a-customer).
  </Step>

  <Step title="[Create an Order](#112-create-an-order).">
    [Create an Order](#112-create-an-order).
  </Step>

  <Step title="[Create Authorisation Payment using Razorpay APIs](#113-create-an-a...">
    [Create Authorisation Payment using Razorpay APIs](#113-create-an-authorisation-payment).
  </Step>
</Steps>

<Info>
  **Handy Tips**
</Info>

For the Authorisation Payment to be successful in a day (for example, 5th June), you should create an Order and the Authorisation Transaction on the same day (5th June) before 11:59 pm.

### 1.1.1 Create a Customer

### Sample Code

Razorpay links recurring tokens to customers using a unique identifier generated through the Customer API.

You can create [customers](/api/customers) with basic information such as `email` and `contact` and use them for various Razorpay offerings. The following endpoint creates a customer.

/customers

Sample Code

````cURL: Curl theme={null}
curl -u [YOUR_KEY_ID]:[YOUR_KEY_SECRET] \
-X POST https://api.razorpay.com/v1/customers \
-H "Content-Type: application/json" \
-d '{
  "name": "Gaurav Kumar",
  "email": "gaurav.kumar@example.com",
  "contact": "+919876543210",
  "fail_existing": "0",
  "notes":{
    "note_key_1": "September",
    "note_key_2": "Make it so."
  }
}'

```java: Java
RazorpayClient razorpay = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

JSONObject customerRequest = new JSONObject();
customerRequest.put("name","Gaurav Kumar");
customerRequest.put("contact","+919876543210");
customerRequest.put("email","gaurav.kumar@example.com");
customerRequest.put("fail_existing", "0");
JSONObject notes = new JSONObject();
notes.put("notes_key_1","Tea, Earl Grey, Hot");
notes.put("notes_key_2","Tea, Earl Grey… decaf.");
customerRequest.put("notes",notes);

Customer customer = razorpay.customers.create(customerRequest);

```python: Python
import razorpay
client = razorpay.Client(auth=("YOUR_ID", "YOUR_SECRET"))

client.customer.create({
    'name': 'Gaurav Kumar',
    'email': 'gaurav.kumar@example.com',
    'contact': '+919876543210',
    'fail_existing': "0",

    },
}
body, err := client.Customer.Create(data, nil)

```php: PHP
$api = new Api($key_id, $secret);

$api->customer->create(array('name' => 'Gaurav Kumar', 'email' => 'gaurav.kumar@example.com','contact'=>'+919876543210','fail_existing' => "0", 'notes'=> array('notes_key_1'=> 'Tea, Earl Grey, Hot','notes_key_2'=> 'Tea, Earl Grey… decaf'));
```csharp: .NET
RazorpayClient client = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

Dictionary options = new Dictionary();

options.Add("name", "Gaurav Kumar"); 
options.Add("contact", "+919876543210"); 
options.Add("email", "gaurav.kumar@example.com"); 
options.Add("fail_existing", "0"); 

Customer customer = Customer.Create(options);

```ruby: Ruby
require "razorpay"
Razorpay.setup('YOUR_KEY_ID', 'YOUR_SECRET')

para_attr = {
  "name": "Gaurav Kumar",
  "contact": "+919876543210",

}
```

### Request Parameters

`email`
: `string` The email address of the customer. For example, `gaurav.kumar@example.com`.

`contact`
: `string` The phone number of the customer. For example, `9876543210`.

`fail_existing` *optional*
: `string` The request throws an exception by default if a customer with the exact details already exists. You can pass an additional parameter `fail_existing` to get the existing customer's details in the response. Possible values:

* `1` (default): If a customer with the same details already exists, throws an error.

### 1.1.2. Create an Order

The Orders API allows you to create a unique Razorpay `order_id`, for example, `order_1Aa00000000001`, that would be tied to the authorisation transaction. Refer to our detailed [Order documentation](/payments/orders) for more details.

You can create a payment against the `order_id` once it is generated.

Use the below endpoint to create an order.

/orders

## MCC | Category | Min Value | Max Value

## 6211 | Financial Services | `100` (₹1) | `20000000` (₹2,00,000)

## 6300 | Financial Services | `100` (₹1) | `20000000` (₹2,00,000)

## 6529 | Financial Services | `100` (₹1) | `20000000` (₹2,00,000)

5960 | Services | `100` (₹1) | `20000000` (₹2,00,000)

For other categories and MCCs, the minimum value is `100` (₹1) and maximum value is 9999900 (₹99,999).

`expire_at` *mandatory*
: `integer` The Unix timestamp that indicates when the authorisation transaction must expire. The default value is 10 years and the maximum value allowed is 30 years.

`frequency` *mandatory*
: `string` The frequency at which you can charge your customer. Possible values:

* `daily`
* `weekly`
* `fortnightly`
* `bimonthly`
* `monthly`
* `quarterly`
* `half_yearly`
* `yearly`
* `as_presented`

`recurring_value` *optional*
: `integer` Determines the exact date or range of dates for recurring debits. Possible values are:

* 1-7 for `weekly` frequency

* 1-31 for `quarterly` frequency
* 1-31 for `half_yearly` frequency
* 1-31 for `yearly` frequency and is not applicable for the `as_presented` frequency.

<Warning>
  **Watch Out!**

  If the date entered for the recurring debit is not available for a month, then the last day of the month is considered by default. For example, if the date entered is 31 and the month has only 28 days, then the date 28 is considered.

  `recurring_type` *optional*
  : `string` Determines when the recurring debit can be done. Possible values are:

  * `on`: Recurring debit happens on the exact day of every month.

  <Info>
    **Handy Tips**
  </Info>

  For creating an order with `recurring_type`=`on`, set the `recurring_value` parameter to the current date.

  * `before`: Recurring debit can happen any time before the specified date.
  * `after`: Recurring debit can happen any time after the specified date.

  For example, if the `frequency` is `monthly`, `recurring_value` is `17` and `recurring_type` is `before`, recurring debit can happen between the month's 1st and 17th. Similarly, if `recurring_type` is `after`, recurring debit can only happen on or after the 17th of the month.
</Warning>

### 1.1.3. Create an Authorisation Payment

<Info>
  **Handler Function vs Callback URL**
</Info>

* **Handler Function**:

When you use the handler function, the response object of the successful payment (`razorpay_payment_id`, `razorpay_order_id` and `razorpay_signature`) is submitted to the Checkout Form. You need to collect these and send them to your server.

* **Callback URL**:

When you use a Callback URL, the response object of the successful payment (`razorpay_payment_id`, `razorpay_order_id` and `razorpay_signature`) is submitted to the Callback URL.

### UPI Intent

UPI Intent is supported on **mWeb (Android)** and **Mobile App (WebView)**. On **Desktop Web**, as UPI Intent is not supported, a QR code is displayed instead.

## Platform | Procedure

## **mWeb** | Customers are redirected to their preferred UPI app to complete the payment. For the complete integration guide, refer to [UPI Intent on Mobile Web](/payments/payment-gateway/web-integration/custom/payment-methods/upi-intent-mweb).

## **Mobile App (WebView)** | UPI Intent requires deep link handling in your Android or iOS app to launch UPI apps from the WebView. For the complete integration guide, refer to [UPI Intent in WebView — Android](/payments/payment-gateway/web-integration/custom/features/webview/upi-intent-android) and [UPI Intent in WebView — iOS](/payments/payment-gateway/web-integration/custom/features/webview/upi-intent-ios).

**Desktop Web** | UPI Intent is not supported. A QR code is automatically displayed for customers to scan with their preferred UPI app. No additional code changes are required.

### UPI Collect

<Warning>
  **Deprecation Notice**

  **UPI Collect is deprecated effective 28 February 2026.** This tab is applicable only for exempted businesses. If you are not covered by the exemptions, refer to the [migration documentation](/announcements/upi-collect-migration/recurring-payments/custom-checkout) to switch to UPI Intent.

  #### Additional Checkout fields

  `customer_id` *mandatory*
  : `string` Unique identifier of the customer created in the [first step](#111-create-a-customer).

  `order_id` *mandatory*
  : `string` Unique identifier of the  order created in the [second step](#112-create-an-order).

  `recurring` *mandatory*
  : `string` Determines if the recurring payment is enabled or not. Possible values:

  * `1`: Recurring payment is enabled.
  * `preferred`: Use this if you want to allow **recurring payments** and **one-time payment** in the same flow.
</Warning>

## 1.2. Using a Registration Link

Registration Link is an alternate way of creating an authorisation transaction. You can create a registration link using the [API](#121-create-a-registration-link) or [Dashboard](/payments/recurring-payments/create#1-create-a-registration-link).

<Info>
  **Handy Tips**
</Info>

* You do not have to create a customer if you choose the registration link method for creating an authorisation transaction.
* You can [use Webhooks to get notifications about successful payments](/api/payments/recurring-payments/webhooks#check-authorization-link-status-using-webhooks) against a registration link.

When you create a registration link, an [invoice](/payments/invoices) is automatically issued to the customer. They can use this invoice to make the authorisation payment.

A registration link must always have the amount (in paise) that the customer will be charged when making the authorisation payment. For UPI, the amount must be a minimum of `₹1`.

### 1.2.1. Create a Registration Link

Use the below endpoint to create a registration link.

/subscription\_registration/auth\_links
