If your platform rolls its own authentication mechanism, utilize the Tight API to provision user accounts and retrieve access tokens.

​
Create a company

When a business opts into your new Bookkeeping product, create their company in Tight. The creation of the company accepts a userId for the business owner from your system, so there is no need to store any Tight identifiers in your platform.

​
Get an access token

Using the userId used to create the user’s company along with your client credentials, make a simple request to retrieve an access token: 
curl -X POST https://sandbox.tight.com/v6/auth/token \
-u client_id:client_secret \
-d userId=your_userId
The Tight API will respond with your granted access token: 
{
    "access_token": "<access_token>",
    "token_type": "Bearer",
    "expires_in": 3600
}
This token can be used to embed Tight UI or to directly hit the Tight API.
