When calling https://{{OKTA_DOMAIN}}/api/v1/users/{{login}} via Postman I am able to successfully retrieve the user information.
When calling the same URL in NodeJS (NestJS/Axios) passing the same SSWS {{apikey}} Authorization header used in the Postman request I receive the following response
I know for certain that it’s not the Authorization header because it’s using the same header being used for the base user API calls that work. Also, I can paste the same URL being used in the Node call into Postman and it works.
