POST oath2/default/v1/introspect getting 404

Questions
1

I’m trying to introspect a token, but getting a 404 when POSTING to:

https://oktapre-dev-845984.pixtulate.com/oath2/default/v1/introspect

I have the client_id and token in the body, as x-www-form-urlencoded.

Specifically, the request returns the html for the Okta 404 page.

Based on https://okta-developer.pixtulate.com/docs/api/resources/oidc/#introspect , this looks like the correct endpoint to me. Can someone assist?

The url should be:
https://oktapre-dev-845984.pixtulate.com/oauth2/default/v1/introspect
instead of:
https://oktapre-dev-845984.pixtulate.com/oath2/default/v1/introspect

Thank you. I can’t believe I missed that.

I’m now getting a ‘invalid_client’ and ‘No client credentials found’ error. I’ve tried including the client_id that I’ve copied from my SPA configuration in both the body as ‘client_id’ and the query params – neither seems to change it. Any ideas?

The post request should be similar:

https://oktapre-dev-845984.pixtulate.com/oauth2/default/v1/introspect?client_id={yourClientId}&token={yourAccessToken}&token_type_hint=access_token

You can try using postman to see if it returns the correct response. It is working for my oktapreview client.

The response is bad request 400. I am unable to find it, why it is giving such kind of errror. Please help.
Thank you

Hi @Shubham6541

The error occurs when Accept and Content-Type headers are not added or have an invalid value. Here is a small cURL example for using the introspect endpoint.

curl --location --request POST 'https://okta-dragos.pixtulate.com/oauth2/default/v1/introspect' \
--header 'Accept: application/json' \
--header 'Authorization: Basic MG9hN...' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'token=TOKEN'

Thanx, Here I was missing Content-type: …
