In this step, you create the Apex classes that call the API and do all of the heavy lifting.

1. In Salesforce, from Setup, enter Apex Classes in the Quick Find box, then select Apex Classes.

2. Click New.

3. To create the JWT Apex class, copy all the code from JWT.apex into the Apex Class tab and click Save.

4. To create the JWTBearerFlow Apex class, go back to to the Apex Classes page, and click New.

5. Copy all the code from JWTBearer.apex to the Apex Class tab and click Save.

6. To create the HttpFormBuilder Apex class, go back to the Apex Classes page, and click New.

7. Copy all the code from HttpFormBuilder.apex into the Apex Class tab and click Save.

8. To create the Vision Apex class, go back to the Apex Classes page, and click New.

9. Copy all the code from Vision.apex into the Apex Class tab and click Save.

10. To create the VisionController Apex class, go back to the Apex Classes page, and click New.
