$750-1500 USD

Paid on delivery
Our software is delivering API callbacks when specific actions are made (ie: When a project is submitted or if its status change). The goal of this mission is to write specific logic inside an API Callback "receiver". The logic is intended to create a validation workflow for our customer. For instance, when a project is submitted and its budget exceed a certain amount, an email should be sent to a specific person. If [another condition] is met, then a second email should be sent, etc. The full scope will be detailed later, as well as API documention (HTTP Rest). If this mission succeed, we might continue to outsource this kind of projects.
