How to initialize an object#

To initialize an object it is required to use apiUrl and mediaUrl parameters specifically for your instance from your console, that way you will get the most stable API work and minimal response time.

greenapi::GreenApi instance1101000001{
    "https://api.green-api.com",
    "https://media.green-api.com",
    "1101123456",
    "87be9e9532fc49748f2a44b9242e55f2e89f4bf97ed6498f80"
    };

How to create group#

Link to the example: createGroupAndSendMessage.cpp.

    nlohmann::json groupCreateGroup{
        {"groupName","GREEN API test group"},
        {"chatIds", {
            "71234567890@c.us",
            "71234567891@c.us"
            }
        }
    };

    greenapi::Response createGroup = instance1101000001.groups.createGroup(groupCreateGroup);

    if (createGroup.error) {
        std::cout << "createGroup error: {status code: " << createGroup.status_code << ", request time: " << createGroup.total_time << ", body: " << createGroup.bodyStr << "}" << "\n" << std::endl;
        return 1;
    }
    else {
        std::cout << "\tcreated: " << createGroup.bodyJson["created"] << "\n" << std::endl;
        std::cout << "\tchatId: " << createGroup.bodyJson["chatId"] << "\n" << std::endl;
        std::cout << "\tgroupInviteLink: " << createGroup.bodyJson["groupInviteLink"] << "\n" << std::endl;
    }

    nlohmann::json sendMessageJson{
        { "chatId", createGroup.bodyJson["chatId"] },
        { "message","I use GREEN-API to send this message to you!" }
    };
    greenapi::Response sendMessage = instance1101000001.sending.sendMessage(sendMessageJson);

    if (sendMessage.error) {
        std::cout << "sendMessage error: {status code: " << sendMessage.status_code << ", request time: " << sendMessage.total_time << ", body: " << sendMessage.bodyStr << "}" << "\n" << std::endl;
    }
    else {
        std::cout << "\tidMessage: " << sendMessage.bodyJson["idMessage"] << "\n" << std::endl;
    }
