Re: [keycloak-user] Customize OpenID/OAuth token

Hi, We're thinking on using Keycloak as our main IDP and SSO solution. At this time, we're using a "custom" IDP server based on Spring and we are investigating if we can migrate our client database to Keycloak without disturbing our users. So, we have seen that, by default, Keycloak answers a token request with a complete JWT token, like this one: { "access_token": "eyJhbGciOiJSUzI1NiIsInR5cCIgOiAiSldUIiwia2lkIiA6ICJEWk4wX1liZUZGNFZMUVdxQ2NWMGFWd0VFbXBlUGlnX1NFaWk3dkozSGRvIn0.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!
