How to access /tyk/oauth/authorize-client/ without using x-tyk-authorization header

Hi,

I am doing OAuth2 flow referring the documentation //tyk.io/docs/basic-config-and-security/security/authentication-authorization/oauth-2-0/.
I can not get authorization code from /tyk/oauth/authorize-client/ endpoint without providing gateway secret. How can I achieve this without gateway secret. Since my client should not have any dependency over gateway.

POST http://tyk-gateway.dev.com:8070/{listen_path}/tyk/oauth/authorize-client
Headers:
Content-Type: application/x-www-form-urlencoded
Authorization: Basic base64(client_id:client_secret)
Body:
response_type=code&client_id=27f6e23bab8b4c9981ba71bfa9f7aa63

This gives response
{ "status": "error", "message": "Forbidden" }
Thank you,
Shiva

This is not meant to be invoked by your client, this is meant to be invoked by your login application hat is authorizing the user. The client should call /authorize/

I have the same problem. and my questions is how invoke /tyk/oauth/authorize-client/ to get code because i get this errors { “error”: “Bearer token malformed” } or { “error”: “Authorization field missing” } thank you.
