# Requests Authentication

Each request you send to GeroSense API must be signed with an authentication token. To receive a new token, use `/login/access-token` endpoint.

curl -X 'POST' 'https://api-b2b.gerosense.ai/api/v1.0/login/access-token' \

Once you have the token, add it in the `Authorization` header of all subsequent requests as shown below:

```bash
curl -X 'POST' 'https://api-b2b.gerosense.ai/api/v1.0/login/test-token' \
     -H 'accept: application/json' \
     -H 'Authorization: Bearer <token>'
```
