# Tokenization APIs

Protecto's Masking API identifies and substitutes Personally Identifiable Information (PII) in text with secure tokens

Protecto API uses appropriate HTTP verbs for every action.

| Method | Description                 |
| ------ | --------------------------- |
| PUT    | Used for updating resources |

**`Features`**

Personally identifiable elements will maintain a uniform token if they are associated with the same token name. For instance, if "`George`" is the original value, consistent tokens will be generated during each masking process, facilitating user-friendly data analysis.

**`Note`**`:` During the trial period, you can mask up to 1000 data entries or values.
