Can I access channel points redemptions using a moderator's token?

API
2

The API only only supports the broadcasters token.

As the broadcaster chooses what tools can/can’t talk to the API on the casters behalf

Additionally, the API only letys you accept/reject on rewards that were created by the calling clientID.

Basically it’s super locked down for security.

And as per the docs

Provided broadcaster_id must match the user_id in the user OAuth token.
