As MagniFinance (that is an online invoicing software approved by the Portuguese Tax and Customs Authority), we want to have an integration of our invoicing API with Magento to allow online stores that uses Magento to invoicing automatically when a customer buy something online.
To do this, you should create/have a sample sandbox Magento account to test and present the result for us.
We will provide you a sandbox account in MagniFinance and our API Documentation that is all that you need to complete the task
Please check attached document and bid
before bid, write Magento--
Before we go forward, we want to know if you can understand our documentation easily.
So, please, try this test: find what is the method that we use to generate an invoice and tell us how you will use it, and send to us and example of calling this method.
