# TokenAssociate

> TokenAssociateTransaction is the Hedera Token Service protobuf message used to associate an HTS token with an account before transfer.

Associates the provided account with the provided tokens. Must be signed by the provided Account's key.

If the provided account is not found, the transaction will resolve to `INVALID_ACCOUNT_ID`.

If the provided account has been deleted, the transaction will resolve to `ACCOUNT_DELETED`.

If any of the provided tokens is not found, the transaction will resolve to `INVALID_TOKEN_REF`.

If any of the provided tokens has been deleted, the transaction will resolve to `TOKEN_WAS_DELETED`.

If an association between the provided account and any of the tokens already exists, the transaction will resolve to `TOKEN_ALREADY_ASSOCIATED_TO_ACCOUNT`.

If the provided account's associations count exceeds the constraint of maximum token associations per account, the transaction will resolve to `TOKENS_PER_ACCOUNT_LIMIT_EXCEEDED`.

On success, associations between the provided account and tokens are made and the account is ready to interact with the tokens.
