Getting {"error":"invalid_grant","error_description":"authentication failure"} in Salesforce?

Question

I am trying to get the Session ID for my salesforce partialbox.

My Code:

curl https://test.salesforce.com/services/oauth2/token -d "grant_type=password" -d "client_id=definitely the correct client id" -d "client_secret=definitely the correct client secret" -d "[email protected]" -d "password=passandsecuritytoken"

What else I did:

• Grant full access in my connected app settings
• Set Ip restrictions to loose ip restrictions
• "All users can authorize themselfes"
• Double checked pass, client id, client secret, username

I am still getting the error {"error":"invalid_grant","error_description":"authentication failure"}.

I searched through the SF forums and StackOverflow questions, but I couldn't find any solution for this. Does anyone know, what else could be the problem here?

Answer 1

I'm still confused and I don't know exactly what's going on, but I had your same problem and I was able to "fix" it by doing the following.

First, relax IP restrictions for the app.

Manage Apps -> Connected Apps -> (The name of my app)

Then setting "IP Relaxation" to "Relax IP restrictions".

As far as I know, there are not IP restrictions in the sandbox app I'm working with but I'm still new to this, so maybe they are hiding somewhere.

Second, in my curl command which looked a lot like your I left out the security token, so the password field was just the password.

I don't really know if I've solved my problem but I'm getting back an access token and not the "invalid_grant" error.

I plan on doing some additional investigating to figure out what's going on but I figured, while I had this question up I'd make sure this answer was here.

Make sure you have done this steps.

*Apps -> Manage Connected Apps -> (The name of my app) -> Edit Application -> OAuth Polices Then set "Permitted users" to "All users may self-authorize".

*Manage Apps -> Connected Apps -> (The name of my app) Then set "IP Relaxation" to "Relax IP restrictions".

Try to make a curl request with TLS 1.1 enabled

curl -v https://login.salesforce.com/services/oauth2/token -d "grant_type=password" -d "client_id=xxxxxxxxxxXXXXXXXXXX" -d "client_secret=123456789" -d "[email protected]" -d "password=xxxxxxxxxx"
