Need to use Kakao Apis for sending updates to clients on his personal chat

Hi

We are in process of integrating Kakao talk APIs with our order management system. In this, we want to check feasibility of following function:

After the user gives consent and we add them into our friend list we want to:
1. Send them transactions messages (in standard format) regarding their order’s progress.
2. For sending messages, we are planning to develop a windows service, which will send message to our registered client. During POC, we came to know that, while sending message, Kakao talk system is asking for login, do we have any alternate option that, we can pass the credentials from the windows job to make it automatic?
a. Do we have any login API which we can use from backend without prompt?
3. Do we require client’s consent every time while sending message or one time consent will work?

hi~

After the user gives consent and we add them into our friend list we want to:

We don’t provide the ability to add friends to Kakao Talk.

  1. Send them transactions messages (in standard format) regarding their order’s progress.

Biz message notifications message look suitable.
(Message API provides sending between Kakao Talk friends connected to the Developers app.)

    a. Do we have any login API which we can use from backend without prompt?

OAuth2-based authentication must be performed on the web or app.
(or in-web browser in Windows program)

  1. Do we require client’s consent every time while sending message or one time consent will work?

Please check the checklist below.
(You only need to get consent once. Sender and receiver, respectively)
