I am trying to connect SFDC, when I created the App in Salesforce, what are the specific checks should I mark to make the connection to work?
When I Try to connect in the Conn Dialog, I am getting this error:
What should I do in order to let it works?
Hi @edgars, thanks for reaching out and joining the n8n community! 
In our Salesforce credential documentation we outline the settings that should be disabled / enabled based on the authentication method that you’re using.
Using Oauth2 we outline the following:
Use these settings for your app:
- Add the Perform requests on your behalf at any time (refresh_token, offline_access) scope in the Selected OAuth Scopes section, along with any other scopes you plan to use.
- Make sure the following settings are unchecked:
- Require Proof Key for Code Exchange (PKCE) Extension for Supported Authorization Flows
- Require Secret for Web Server Flow
- Require Secret for Refresh Token Flow
- In the API (Enable OAuth Settings) section, select Click to reveal to reveal the consumer secret.
- Copy the Consumer Key and Consumer Secret and add these to the appropriate fields in n8n.
Happy building!
Just for the record, I am sharing the print screen from my Config, I just recommend you guys to do the same with some config that actually works, just in case I added the whole scopes:
Hi @edgars Looks like you still have the PKCE checked, Require Secret for Web Server Flow & Require Secret for Refresh Token Flow which is likely the reason you are getting the error message you are.
@Ludwig Has listed out the details that need to be unchecked for the authentication to work, keeping any of those checked can result in an error. It’s stumped me a few times in the past.
