# Implement Tokenized Sending

Before you enable Tokenized Sending in Marketing Cloud Engagement, review requirements and test the functionality. Note that some features don't work when Tokenized Sending is enabled but not yet implemented.

1. To ensure successful implementation, review the tokenized sending prerequisites and the Get and Resolve Token API specifications.
2. Develop your REST APIs for getting and resolving tokens.
3. Configure your APIs.
    1. Allowlist applicable IP addresses.
    2. From Setup, under Security, enter the endpoint and authentication credentials.
4. To test your configuration, save your endpoint and authentication credentials in the Security section.
    
    Review results of the test and fix your configuration accordingly. Improper configurations aren't saved.
5. Create a sample list with sample tokens, and import it.
6. Perform a test send using the sample list.
7. After a successful test send, your account is ready for production sends.
