Prefill Amount Fields in Payment Button

You can prefill the amount fields present in your Payment Button. This provides a better user experience for your customers.

Prefill Item Quantity

You can set a particular item quantity for a product.

Let us assume you want to sell iPhone 12 max smartphone cases for RM39. 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:

Log in to the
Curlec Dashboard
and create a Payment Button titled Limited Edition iPhone 12 Phone Case. Ensure you select the Buy Now button type.
In the Amount Details section, create an amount field called iPhone 12 Max Case using Item with Quantity as the field type.
Configure the Customer Details section as required.
Create the Payment Button.

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

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

When you embed the button code on your website, add the following parameter:
data-prefill.amount.iphone_12_max_case="1"
The parameter structure is explained below:
Handy Tips
- Ensure that the field-level validations are in place. If you enter a character in the amount field, say 100 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:
<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.

Handy Tips

- 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 RM100, the Cash field cannot be prefilled with a value higher than RM100.
