FAQ

Q. Should I pay for using the Line Messaging API?

A: Not at all. According to LINE's official 2026 policy, the Messaging API cost primarily depends on the calculation of message counts. Currently, receiving and replying to user messages does not count; however, calling the Messaging API's Push, Multicast, Broadcast, and Narrowcast methods will count.

LINE OA currently offers three plans: free plans and fixed monthly fees (Communication, Light, Standard). The pricing varies in different regions such as Japan, Taiwan, and Thailand, and you can subscribe to one according to your needs.
For detailed information on how to count Line messages, please refer to the official counting standards.

Methods	Free or Count

Channel Access Token	Free
