[Irudaya5F8B]

Please check that code parameter is valid for only 30secs. 

[Solem Khan5FDC]

Post is too old.

I was able to fix it is removing HTTP/1.1 in grant_type.
grant_type=authorization_code

Also, don't share your code/keys publicly.

[Louis21767626u5m0]

I don't understand why I am getting "Missing grant_type value" when I am including the grant_type value as 

grant_type=authorization_code in my POST

Attached is a jpg of my POST:

Where else can I get help on this? I ran out of options.

Please help,

[Louis21767626u5m0]

Having the same issue

[Louis21767626u5m0]

I  was able to resolve my issue, by using:

https://secure.na4.echosign.com/oauth/v2/token

instead of 

https://api.na4.echosign.com/oauth/v2/token

I hope that helps you.

[Louis21767626u5m0]

Hello, 

I am trying to get access token using this post request:

https://secure.na3.echosign.com/public/oauth/v2/token?
code=xxxxxxx&
client_id=xxxxxxxxx&
client_secret=xxxxxxxxxxx&
redirect_uri=https://mydomain.com&
grant_type=authorization_code

When I send this request I get the following message:

{

    "error_description": "Missing grant_type parameter value",

    "error": "invalid_request"

}

I am not missing the grant_type parameter as you can see from my url request.

What am I doing wrong?

Please help, Thank you.

[SimonATS]

the Post request to get the access token cannot be done with url parameters, see

https://secure.eu1.echosign.com/public/static/oauthDoc.jsp

also you need to call the api endpoint

https://api.eu1.echosign.com 

(adjust for your region/shard if needed)

[Louis21767626u5m0]

Hi Simon, thanks for your response.

The reason I am calling the api endpoint as https://secure.na3.echosign.com is because I've read that it should be the same as the url in my Adobe Sign account as you can see in the image I am attaching (url.jpg). But you are saying it should be https://api.eu1.echosign.com?

I am also getting 401 (Unauthorized)

any other suggestions please let me know.

Thanks,

[defaultks5q4ixbt36z]

Please ensure the request is sent under Content-Type "x-www-form-urlencoded"

Did you manage to find a solution for your issue with oauth/v2/token? 

[Victor24451361scns]

Make sure you don't pass all parameters as query string, it has to be x-www-form-urlencoded

[Brian25598069ivpr]

Using "x-www-form-urlencoded" instead of a "raw" body fixed my issues. Thank you!

[Mr Seaniepie]

I've found that removing the 'v2/' from the url works for me. So the url I used for refresh was:

https://api.na1.adobesign.com/oauth/refresh?grant_type=refresh_token&refresh_token={myToken}&client_...}

The header, as stated before, MUST be:

Content-Type: application/x-www-form-urlencoded

I hope this helps others.
