Hi William Diehl,

                             I was going through this question Names and Roles Provisioning user_id and am using (Names and Role - Canvas LMS REST API Documentation ) api to retrieve user_id value  but while following flow mentioned in docs ### JWT Access Tokens for LTI2 Tools - Canvas LMS REST API Documentation . i encountered with reg_key which require in authorize api. 

 

curl https://<canvas>/api/lti/accounts/1/authorize \  
-F 'grant_type=authorization_code' \
-F'assertion=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiIxMDAwMDAwMDAwMDAwMyIsImF1ZCI6Imh0dHA6Ly9jYW52YXMuZG9ja2VyL2FwaS9sdGkvYXV0aG9yaXplIiwiZXhwIjoxNDg5Njc0NTAyLCJpYXQiOjE0ODk2NzQ0NDIsImp0aSI6ImQ4MjA0NDBjLTI3YzMtNDg2YS1hZjM5LWQzZDQxOGI4ZDNkYSJ9.S3SxxsSKAKhT8ViHuCDBxp9fbzdYGKJEBftftJMX4-E' \      
-F 'code=<reg_key>'

because when tool being launched with lti 1.3  that time no such parameter reg_key am getting.

have you use name and roles provision api (Names and Role - Canvas LMS REST API Documentation) to
get user_id ? if yes can you mention the flow to get user_id in lti 1.3.

Thanks.
