## AWS Lambda token fetcher

Small lambda written in Golang and used to get `viewables:read` 2-legged tokens, which in conjunction with AWS API Gateway creates the minimal backend needed for serving to Forge Viewer the access tokens.

### Setup

1. create a deployment package following the [AWS guide](https://docs.aws.amazon.com/lambda/latest/dg/lambda-go-how-to-create-deployment-package.html) or create a new lambda through AWS portal and upload the zip file (either prepared by you or downloaded from [releases](https://github.com/apprentice3d/aws-lambda-token-fetcher/releases))(A).

2.  Set the environment variables with your Autodesk Forge credentials (as shown in bellow at B).

3. Through AWS portal, in API Gateway, create a new API, set the integration type as lambda and specify the AWS lambda created at step 1.

4. Use the endpoint created by the API Gateway, in your apps to get the `viewables:read` tokens, used by viewer to display your models:

```javascript

    let options = {

        env: 'AutodeskProduction',

        getAccessToken: (onGetAccessToken) => {

            fetch('https://9irt90dm6j.execute-api.us-east-1.amazonaws.com/prod')

                .then(response => response.json())

                .then(data => {

                    let accessToken = data["access_token"];

                    let expireTimeSeconds = data["expires_in"];

                    onGetAccessToken(accessToken, expireTimeSeconds);

                })

        }

    };

```
