Odoo 19 SaaS and Windcave Payment Integration

We are looking for an experienced developer to create a simple payment integration between Odoo 19 SaaS and the Windcave payment gateway. The aim is to allow customers to complete payment as part of, or immediately after, the Odoo sales or website checkout process without us having to manually create and send a Windcave Paylink. As Odoo SaaS does not allow custom modules, the solution may involve Odoo Studio, webhooks, Windcave’s API, and a small externally hosted payment bridge. The solution should: Provide a simple and professional customer payment experience. Automatically create the Windcave payment request. Confirm or update the order in Odoo after successful payment. Securely handle payment notifications and prevent duplicate processing. Include setup instructions and basic testing. Applicants should have experience with Odoo, API integrations, webhooks and hosted payment gateways. This is a fixed-price project only. Please include your proposed solution, total fixed price and expected deliverables in your application.
