Dear Sitecore OrderCloud team,
First of all, I'm really appreciated for your POC on how to integrate OrderCloud with Google IDP through the OpenID Connect. With your instructions, I have successfully set up the connection between my OrderCloud instance with Google IDP.
However, due to some requirements on our customer, currently I have tested the OpenID Connect of OrderCloud with the OAuth IDP of LinkedIn and it failed at the step of get the access token from LinkedIn (https://www.linkedin.com/oauth/v2/accessToken) (please see the below attached images for my local environment setups ). It seems that the LinkedIn only allows to retrieve the access token by the GET method instead of POST (https://stackoverflow.com/questions/16404762/linkedin-get-token-returns-http-1-1-400-bad-request-error).
I will really appreciate if Sitecore OrderCloud team can provide me any suggestion to overcome this issue.
Thank you all so much & have a great day.
Best regards.
Phu Pham.
