On October 29, 2019 we announced a breaking change. That all broadcast API will stop working on March 4th, 2020. Matching the deprecation date set by the policy update shared on August 29, 2019.
We recommend apps to migrate to the new policy and migrate to use the Send API as soon as possible.
Now I m using Graph API v9.0 and have no idea how to do it without Broadcasting Messages API.
