# Reactivate a token group

POST https://api.ocpplab.io/emsp/token-groups/{group_id}/reactivate

SUSPENDED members are pushed to partners with ``valid: true`` again. Revoked members stay invalid.

## Request

### Path parameters

- `group_id` (integer, required) — The token group's ``id``.

### Headers

- `Idempotency-Key` (string, required) — A unique key you choose for this call, e.g. a UUID. Retrying with the same key returns the first result instead of acting twice.
