# Data Integration

The JWT Security service generates a forward with a token set into gm-data. The Grey Matter Data service uses Grey Matter JWT Security service as a JWT Token generator. To use in conjunction with `gm-data`, see the docs:

* [API Basics](../../../../platform-services/data#api-basics)
* [Client Tutorial](../../../platform-services/data/client-tutorial)
* [Environment And Deployment](../../../../platform-services/data#environment-and-deployment)
* [Authentication and Authorization](../../../platform-services/data/internals/auth)

For use with `gm-data`, one of the values in the `JWT_API_KEY` variable must match the value provided to `JWT_API_KEY` in the `gm-data` deployment.
