Oauth2 not working in 7.10.4

[ghost]

Issue

There are two issues here.

The first is on a clean instance of SuiteCRM the only Grant that seems to be generated is Client credential even though Password Grant is selected.

Using the Client credential does not seen to work and results in the following error. Here is a response from Postman.

Expected Behavior

Oauth2 authorization should work.

Actual Behavior

Server responds as unsupported_grant_type.

Possible Fix

Steps to Reproduce

Issue 1

1. On clean instance of Suite 7.10.4 go to admin page -> OAuth2 Clients and Tokens
2. New Password Client
3. Enter name and secret and save.
4. Notice that it shows as Allowed Grant Type:Client Credentials

Issue 2.

1. On clean instance of Suite 7.10.4 go to admin page -> OAuth2 Clients and Tokens
2. Create new Client credentials client
3. Enter name and secret and save.
4. Use client_id and secret and post to api/oauth/access_token? with parameters descried in documentation

@LEAP-nishit we've changed the behavior of the API and working on it to make it better.
Could you test it in this branch please? #5806
The methods of sending calls have been changed as well, but there is a documentation for them [ https://github.com/salesagility/SuiteDocs/pull/90 ]

Also, if you are using Postman, there is an easier way to get access token.

Thank you!

So how can I get a key to interact with the API until this is fixed? Is there a way to comment out authorization?

Even I am facing the same issue. How to setup using postman? I am unable to generate a new access token using postman. An example would be great.
Thanks!

Hi @prasadh13, in my case I successfully set up the postman and using Password and Client Credentials auth also, using the fallowing steps in my SuiteCRM instance folder:

$ openssl genrsa -out Api/V8/OAuth2/private.key 2048
$ openssl rsa -in Api/V8/OAuth2/private.key -pubout -out Api/V8/OAuth2/public.key
$ sudo chmod 600 Api/V8/OAuth2/p*.key
$ sudo chown www-data:www-data Api/V8/OAuth2/p*.key

also you will need an OAuth2 Client, call the URL:
{Your-SuiteCRM-URL}/index.php?module=OAuth2Clients and add a new Client, for e.g:

Postman settings:
Authorization -> Get New Access Token

Click: Request Token

Click: Use Token

I hope it helps

Reference to the doc site: https://docs.suitecrm.com/developer/api/version-8/configure-suitecrm/
probably needs some update..
