Mock an OpenID Connect discovery document

A GET mock at /.well-known/openid-configuration with issuer, authorization_endpoint, token_endpoint, and jwks_uri.

Stands in for a third-party API endpoint.

Response payload

{
  "issuer": "https://quickmock.dev/m/YOUR-SLUG",
  "authorization_endpoint": "https://quickmock.dev/m/YOUR-SLUG/authorize",
  "token_endpoint": "https://quickmock.dev/m/YOUR-SLUG/token",
  "jwks_uri": "https://quickmock.dev/m/YOUR-SLUG/.well-known/jwks.json",
  "response_types_supported": [
    "code"
  ],
  "subject_types_supported": [
    "public"
  ],
  "id_token_signing_alg_values_supported": [
    "RS256"
  ]
}

Fields worth knowing

Field	What it means
issuer	The issuer URL clients compare against a token's iss claim; it must exactly match the base URL.
authorization_endpoint	Where a client sends the user to log in.
token_endpoint	Where a client exchanges a code for tokens.
jwks_uri	Where a client fetches the public keys — pairs with the jwks-endpoint template.

Create the mock

curl -X POST https://quickmock.dev/api/mocks \
  -H 'Content-Type: application/json' \
  -d '{
  "method": "GET",
  "response_status": 200,
  "content_type": "application/json",
  "path_suffix": ".well-known/openid-configuration",
  "response_body": "{\"issuer\":\"https://quickmock.dev/m/YOUR-SLUG\",\"authorization_endpoint\":\"https://quickmock.dev/m/YOUR-SLUG/authorize\",\"token_endpoint\":\"https://quickmock.dev/m/YOUR-SLUG/token\",\"jwks_uri\":\"https://quickmock.dev/m/YOUR-SLUG/.well-known/jwks.json\",\"response_types_supported\":[\"code\"],\"subject_types_supported\":[\"public\"],\"id_token_signing_alg_values_supported\":[\"RS256\"]}"
}'

Call it

curl https://quickmock.dev/m/<slug>/.well-known/openid-configuration

What you get

GET /m/<slug>/.well-known/openid-configuration -> 200 an OIDC discovery document
replace YOUR-SLUG with the mock's real slug before using it

How this differs from the real thing

Every URL in this document is a placeholder built from YOUR-SLUG — replace it with the mock's real https://quickmock.dev/m/<slug> URL before pointing a real OIDC client at it. Editing the response body needs the admin token from the create banner; see /guide/manage-mocks-from-any-device for how that works.
