  Dynamics 365 FO – Fetch Customer Details Integration API (With Full X++ Code + JSON Explanation) In this article, I am sharing the complete implementation of my Customer Details Integration API in Microsoft Dynamics 365 Finance & Operations (D365 FO). This API is designed to: ✔ Fetch a specific customer when CustAccount is provided in the JSON ✔ Fetch all customers when CustAccount is NOT provided ✔ Return multiple addresses and multiple contacts for each customer ✔ Return financial dimensions (BusinessUnit, CostCenter, Department, Project) ⭐ How the API Works 1.
