1. Create the Authorisation Transaction

You can create an authorisation transaction using Razorpay APIs or Registration Link.

1.1. Using Razorpay APIs

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

1. [Create a Customer](#111-create-a-customer).

   Create a Customer.

2. [Create an Order](#112-create-an-order).

   Create an Order.

3. [Create Authorisation Payment using Razorpay APIs](#113-create-an-a...

   Create Authorisation Payment using Razorpay APIs.

Handy Tips

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

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

You can create 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 -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": "[e-mail]",
  "contact": "[phone]",
  "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","[phone]");
customerRequest.put("email","[e-mail]");
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': '[e-mail]',
    'contact': '[phone]',
    'fail_existing': "0",
    'notes': {'note_key_1': 'September', 'note_key_2': 'Make it so.'}
    })

        "notes_key_1": "Tea, Earl Grey, Hot",
        "notes_key_2": "Tea, Earl Grey… decaf.",
    },
}
body, err := client.Customer.Create(data, nil)

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

$api->customer->create(array('name' => 'Gaurav Kumar', 'email' => '[e-mail]','contact'=>'[phone]','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", "[phone]"); 
options.Add("email", "[e-mail]"); 
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": "[phone]",
  "email": "[e-mail]",
  "fail_existing": "0",
  "notes": {
    "notes_key_1": "Tea, Earl Grey, Hot",
    "notes_key_2": "Tea, Earl Grey… decaf."
  }
}

Razorpay::Customer.create(para_attr)

```javascript: Node.js
var instance = new Razorpay({ key_id: 'YOUR_KEY_ID', key_secret: 'YOUR_SECRET' })

instance.customers.create({
  name: "Gaurav Kumar",
  contact: "[phone]",
  email: "[e-mail]",
  fail_existing: "0",
  notes: {
    notes_key_1: "Tea, Earl Grey, Hot",

Handler Function vs Callback URL

• 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.

Additional Checkout Fields

customer_id mandatory : string Unique identifier of the customer created in the first step.

order_id mandatory : string Unique identifier of the order created in the second step.

recurring mandatory : boolean Possible values:

• true: Recurring payment is enabled.
• false: Recurring payment is not enabled.

Handy Tips

The recurring parameter also supports the value preferred. Use this when you want to support recurring payments and one-time payment in the same flow.

save mandatory : integer Indicates whether to save the card details. Possible values:

• 1: Save the card details.
• 0: Do not save the card details.

consent_to_save_card mandatory : integer Indicates whether you have taken the customer’s consent for tokenising the card. Possible values:

• 1: Taken the customer’s consent.
• 0: Not taken the customer’s consent.

After this step, you can proceed to integrate with the Fetch Token API.

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 or Dashboard.

Handy Tips

• 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 against a registration link.

When you create a registration link, an invoice 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 cards, the amount must be a minimum of ₹1.
