Example🔗

Let us assume you want to sell iPhone 12 max smartphone cases for ₹399. You create a Payment Button titled Limited Edition iPhone 12 Phone Case to sell the product. You can ensure that when the customer clicks the Payment Button, the quantity to be purchased appears pre-selected as 1.

Steps🔗

To add prefilled item quantity field:

1. Log into the Razorpay Dashboard and create a Payment Button titled Limited Edition iPhone 12 Phone Case. Ensure you select the Buy Now button type.

2. In the Amount Details section, create an amount field called iPhone 12 Max Case using Item with Quantity as the field type.

3. Configure the Customer Details section as required.

4. Create the Payment Button.

5. Copy the embed code to add the Payment Button.
   Here is a sample embed code:

    Button Embed Code
   Copy<form><script src="https://checkout.razorpay.com/v1/payment-button.js"
   data-payment_button_id="pl_GE9RTzFzrOTdSj"></script> </form>
   

6. When you embed the button code on your website, add the following parameter:

    Amount Field Parameter
   Copydata-prefill.amount.iphone_12_max_case="1"
   

   The parameter structure is explained below:

   Field Name	Amount Field Label	Value
   data-prefill.amount	.iphone_12_max_case	1

   Handy Tips

   • Ensure that the field-level validations are in place. If you enter a character in the amount field, say 1oo or Hundred, the field will not get populated.
   • If the amount field label consists of two words, add an underscore as a separator of two words. For example, the two words in the iPhone 12 Max Case field should be separated by an underscore. That is, iphone_12_max_case.
   • If the item is out of stock or has less quantity available, though the field will appear prefilled, the customer will not be able to purchase the product.

The updated embed code looks like this:

 Updated Button Embed Code
Copy<form><script src="https://checkout.razorpay.com/v1/payment-button.js"
data-payment_button_id="pl_GE9RTzFzrOTdSj" data-prefill.amount.iphone_12_max_case="1">
</script> </form>

This ensures that the iPhone 12 Max Case item quantity will always appear prefilled as 1.

Suppose you are the director of an NGO that is raising funds for flood relief. Apart from the relief packages such as sanitation kits (worth ₹750) and dry ration kits (worth ₹1000), you are adding a field to collect cash.

You want to prefill the Cash field for donors. And, you want to show ₹500 as a suggested donation amount. Donors can donate this amount, ₹500, or change the amount and then pay.

Steps🔗

1. Log into the Razorpay Dashboard and create a Payment Button titled Contribute to Assam Flood Relief. Select the Donations button type.

2. In the Donation Amount section, create an amount field called Cash.

3. Configure the Customer Details section as required.

    Amount Field Parameter
   Copydata-prefill.amount.cash="500"
   

   The parameter structure is explained below:

   Field Name	Amount Field Label	Value
   data-prefill.amount	.cash	500

   Handy Tips
   

   • Ensure that the field-level validations are in place. If you enter a character in the amount field, say 1oo or Hundred, the field will not get populated.
   • If you are using a custom field name for amount, ensure that the field name is entered in lowercase and is separated by an underscore. For example, if the amount field name is Cash Funds, enter the suffix as cash_funds.
   • Pre-population of the amount field is subject to the Minimum and Maximum Input Price set for the amount field. For example, if the Maximum Input Price has been set as ₹1000, the Cash field cannot be prefilled with a value higher than ₹1000.

The updated embed code looks like this:

 Updated Button Embed Code
Copy<form><script src="https://checkout.razorpay.com/v1/payment-button.js"
data-payment_button_id="pl_GENk7eNBLg6ukw" data-prefill.amount.cash="500">
