Custom WordPress Plugin for CartFlows & SumUp (1-Click Purchase)

Job ID: 39759101

Budget: $10 – $30 USD

We are looking for an experienced developer to create a custom WordPress plugin. The goal is to build a seamless integration between CartFlows (WooCommerce) and the SumUp payment gateway.

Project Overview
The flow of our sales funnels will be as follows:

Landing Page

Checkout

Upsell

Downsell

Upsell

Thank You Page

The most critical requirement for this integration is to enable 1-Click Purchase. This means the plugin must save the customer's card details from the initial checkout and then use a token to process future payments within the same funnel.

Technical Requirements
CartFlows provides a sample plugin that allows you to create a bridge between CartFlows and a custom payment gateway, provided the gateway supports card tokenization. SumUp supports this functionality and has a comprehensive API reference.

Important Notes (Please Read Carefully)
To avoid wasting time, please note the following:

The official SumUp WordPress plugin does not support 1-Click Purchase.

SumUp's hosted payment page does not tokenize cards.

You must use the SumUp Card Widget to save and tokenize a card, or work directly via the SumUp API.

How to Apply
We will only consider proposals from candidates who have read the entire description. Please include the exact string "Sumup+Cartflow" at the end of your application message.

We will begin reviewing candidates on September 4, 2025, at 9:00 AM UTC+1.
