KeyCloak-Rest-Token

## Obtain Token and Invoke Service

The token is verified/validated using the public key of the Keycloak server.

In Keycloak:

1. Go to Realm Settings -> Keys and click the Public key button for the key with the highest priority
2. A popup appears with long string of text (the public key)
3. Copy/paste this public key
4. In the backend: use a JWT library and provide it the public key to verify that the token is valid

Have you by chance tried using the rest api within a web application to get a token? Particularly from something like a React app? No matter what I try I can’t seem to get it to work.

@jbouder I'm having the same problem. I have a react app and I'm trying to use my own UI login screen and trying to call the keycloak rest endpoint that gives me the access token.

Have you find out how to do it properly?

I did actually, the main issue I was experiencing actually was due to how I was posting my data, was using FormData, when it should actually be UrlSearchParams. Here is the gist of what I'm doing (might have to tweak a bit, i'm using a default axios instance, and for this code snipped I pulled some of that in for you)...
axios({ method: 'post', headers: { 'Content-Type': 'application/x-www-form-urlencoded', }, url: '${SSO_ISSUER_URL}/realms/${SSO_KEYCLOAK_REALM}/protocol/openid-connect/token', data: new URLSearchParams({ client_id: SSO_CLIENT_ID, grant_type: 'password', username: USERNAME, password: PASSWORD, })
