[FIXED] This API does not exist (migration to helix)

[BarryCarlyon]

The old Extension API’s have been migrated to helix equivalents

See

• Reference | Twitch Developers For Transactions
  and
• Reference | Twitch Developers onwards for everything else

This migration doesn’t effect get/set calls made via the JS helper only EBS/Server calls.

From your OP not sure if GETTING or SETTING Config segments

• Get: Reference | Twitch Developers
• Set: Reference | Twitch Developers

Which have a different URL structure and payload layout to previous but the same authentication requirements/JWT construction.
