Title: Woocomerce API internal server error when adding order Last modified: February 10, 2021 --- # Woocomerce API internal server error when adding order * Resolved [lyoncapsdev](https://wordpress.org/support/users/lyoncapsdev/) * (@lyoncapsdev) * [5 years, 3 months ago](https://wordpress.org/support/topic/woocomerce-api-internal-server-error-when-adding-order/) * Hello, I am developing a online store with React-Native, which allows customers to purchase products. I am using the woocomerce API, a WordPress plugin. * When I try to create an order from the API, it gives me an internal server error. * Here is my API call to create an order : * ``` const data = { payment_method: "mollie_wc_gateway_creditcard", payment_method_title: "Mollie - Carte de crédit", set_paid: false, billing: { first_name: "John", last_name: "Doe", address_1: "1 rue des champs", address_2: "", city: "Paris", state: "FR", postcode: "75000", country: "FR", email: "john.doe@example.com", phone: "0636......" }, shipping: { first_name: "John", last_name: "Doe", address_1: "1 rue des champs", address_2: "", city: "Paris", state: "FR", postcode: "75000", country: "FR", email: "john.doe@example.com", phone: "0636......" }, line_items: [ { product_id: 3884, quantity: 2 }, { product_id: 3198, variation_id: 3375, quantity: 1 } ], shipping_lines: [ { method_id: "lpc_sign", method_title: "Colissimo avec signature", total: "6.70" } ] }; return await api.post('orders', data).then((response)=>response); ``` * I want to create an order with two products and with “Colisimo avec signature” delivery method. * And here is the response : * ``` { "additional_errors": [], "code": "internal_server_error", "data": { "status": 500 }, "message": "
