Add payment link and payment form feature to existing iOS app, PHP backend.

Hello everyone! I am excited to test out a new developer who will work with us on many projects. I imagine the below to be an easy task, but I might be wrong. It is ok to give me suggestions on better ways to do things. Quick test job: add a payment link feature. Background: Current iOS payment app, has a php backend for api processing, data storage and displaying payment receipts. I would like to test out feature of generating a payment link on the app. The link will be for sending through email or sms. The link will go to hosted a payment form on the backend. The link should be a short link that houses app user ID and the amount requested (logged in database). Example: [login to view URL] When link is loaded, it displays the app users business name and how much it is requesting. Similar to an invoice. When payment is made, it is logged under the right app user ID’s account. API for processor will be provided. Webform should be able to load Apple Pay certificate to use Apple Pay on form when loaded by iOS Safari. Please add the word “Friendly” to your bid so that I know you read the description and didn’t use a bot to bid. Thank you!
