The "Sentiment Analysis Option", which was available in the Asynchronous HTTP Interface v1, was not supported in v2. However, we are currently developing this option to be available in v2 as well.

■ Schedule

• July 31, 2026: v2 Sentiment Analysis Option Release (Planned)
• December 31, 2026: v1 End of Support (Planned).

Customers currently using v1 are requested to migrate to v2 by December 31, 2026. Migration to v2 can be done by changing the request destination endpoint as follows.
