# Update a token

PATCH https://api.ocpplab.io/emsp/tokens/{token_id}
Content-Type: application/json

Only the fields sent change. ACTIVE and SUSPENDED tokens are pushed to partners again before the change is saved. If the push to roaming partners fails the call answers 502 and the token is left as it was; retry with the same Idempotency-Key.
