# Tokenization V1

### Requirements[​](https://dashboard.doku.com/docs/docs/jokul-direct/tokenization/jokul-token-guide#requirements) <a href="#requirements" id="requirements"></a>

1. Make sure you have integrated with either Credit Card or Direct Debit
2. Make sure that you sent `customer.id` parameter on the request to DOKU in order to activate the tokenization feature

### Integration steps[​](https://dashboard.doku.com/docs/docs/jokul-direct/tokenization/jokul-token-guide#integration-steps) <a href="#integration-steps" id="integration-steps"></a>

1. Get token list
2. Show token list to the customer
3. Use the token for future payment

#### 1. Get token list[​](https://dashboard.doku.com/docs/docs/jokul-direct/tokenization/jokul-token-guide#1-get-token-list) <a href="#id-1-get-token-list" id="id-1-get-token-list"></a>

To get token list, you will need to hit this API through your backend:
