Loading SDK / payment form
Now you can encapsulate the order ID generated in the previous step into a config object and use it to load the Revup SDK on your website. As previously mentioned, the SDK allows you to display:
- A predesigned payment form or,
- A set of independent input iframes, if you wish to customize your payment form.
No matter what you choose, generating an order ID first is always a mandatory requirement.
Once the payment form is loaded, your website is briefly no longer in charge of the transaction, as the form will take care of everything: the user will fill in the payment card details in the appropriate inputs, and when you click the "Submit Payment" button, the SDK will manage the payment process by communicating internally with the Revup API.
Remember that order IDs are one-time-use only.
Once they are used to create a transaction, the order remains permanently linked to the transaction, and you can't use it again. For example, when the user submits the payment and fails, generate a new order ID and provide it to the SDK to try again.
