# TokenAssociate

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.
