Payment acceptance widget

Description

The widget allows you to set up payment acceptance with minimal integration. On your part, you will need to configure the reception of webhooks and place the widget on your application page.

Payment acceptance

Depending on the selected type of payment acceptance, we will send the appropriate type of webhook

Webhook when paying an invoice Webhook when adding funds to a personal address

Orphan transaction webhook. In order to handle cases of sending a payment with the wrong currency, contact your personal manager to issue a webhook about the orphan transaction

Invoices

For each new payment, the user receives a new invoice with a unique address that is valid for a limited time. The invoice can be issued in crypto or fiat currency, with a fixed amount or without it for free payment.

---

Personal addresses

Payment acceptance allows you to create a list of crypto addresses for each payer. These addresses are permanently assigned to the user.

Connection

The connection is made using the HTML tag <iframe/>

Example:

<iframe 
    allow="clipboard-read; clipboard-write"
    src="https://widget.apollopayment.io/181a197e-3b00-4359-8298-6097aeb52c69"
></iframe>

The attribute allow="clipboard-read; clipboard-write" is required so that your customers can copy the payment address by clicking the "Copy" button

Available options

The parameters are passed to the query

To insert data into the query, it must be escaped. In JavaScript, this can be done using the function encodeURIComponent

const payinCryptoInvoiceId = encodeURIComponent('#12345');
