## Introduction

[JSON Web Tokens](https://jwt.io/) (JWT - pronounced “jot”) are used by many services to represent and exchange information in a secure manner. When creating a JWT token, you need to supply the following information:

- **Algorithm**: The algorithm to be used when computing the JWT
- **Payload**: The payload to be included in the JWT. Payloads typically contain a set of [Claims](https://auth0.com/docs/secure/tokens/json-web-tokens/json-web-token-claims#reserved-claims).
- **Auto generate 'iat' & 'exp' claims**: When using JWTs, two common claims are *iat* (Issued At) and *exp*. When this checkbox is selected, Tines will insert an iat claim corresponding to the time the action runs, and an exp claim corresponding to the current time + 1 hour, into the JWT payload.
- **Private key**: The private key to be used to sign the JWT.

When an action containing a [`CREDENTIAL` formula expression](https://www.tines.com/docs/formulas/referencing-data#from-credentials) referring to a JWT-type credential runs, Tines will build a JWT and insert it into the options block in place of the expression. For example, given  `<<CREDENTIAL.my_jwt_user_credential>>` and a corresponding credential, at runtime, Tines will substitute in a string similar to the following:
