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.

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.

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.

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)

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,

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

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

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.
