Azure AD B2C: Getting Error while refreshing Token in iOS App

Amita Jain 21

I am trying to refresh token using Token end point in my iOS App, but getting error as:
"error_description": AADB2C90083: The request is missing required parameter: grant_type

Refresh Token endpoint is: https://{myTenant}.b2clogin.com/{myTenant}..onmicrosoft.com/B2C_1_SignInSignUpFlow/oauth2/v2.0/token

I am sending below parameters to the request:
"grant_type": "refresh_token",
"refresh_token": {my_refreshToken},
"client_id": {my_client_id},
"redirect_url": {my_app_redirect_url}

Please tell me, if I am missing anything?

Hi @Amita Jain , have you seen this thread? If so please let me know so I can look into this further.

Update: User solved issue by using GET instead of POST

Thank you,

Hi @James Hamil , I have found the solution for this problem. I was sending POST request instead of GET request, hence the parameters I was sending were getting ignored. :)
