Custom labels, Placeholders and Descriptions are fields that are in table “strapi_core_store_settings”.
I believe that “naturally” there is no way to obtain this data, but if you implement a service that accesses the strapi function shown below, you can get it and return it in a custom API.
const prefixContentManager = "plugin_content_manager_configuration_content_types";
let contentID = "api::octuber-reports-2023.octuber-reports-2023";
let sqlStatement = `SELECT value FROM strapi_core_store_settings WHERE [key] = ${prefixContentManager}::${contentID}`;
const result = await strapi.db.connection.raw(sqlStatement);
console.log("Here are the ContentManager FormView json with values:", result);
I haven’t tested this code, but I believe it works, just adapt it to your return needs.
