Existing credentials. i want to use it for n8n tool

[Jonathan_Liu]

Describe the problem/error/question

i have several users that will use 1 n8n workflow from a chat UI.
i already have their salesforce credentials(ie. access and refresh token). I want to use n8n built in Tool for salesforce.
how do i setup the n8n built in Tool for salesforce oauth2? i plan on passing the tokens via body metadata.
I’ve read Salesforce credentials | n8n Docs , but this doesnt mention for 0auth2, the access token already provided.

i am not planning jwt. it does not make sense for my application.

Please share your workflow

n8n.io - Workflow Automation

## Information on your n8n setup
 n8n cloud, desktop app

Hey @Jonathan_Liu ,

Welcome to the community.
Have you tried Using Expressions in the Credential?
In the OAuth2 credential setup, you can use expressions to reference workflow data: Access Token: {{ $json.access_token }} or {{ $node["HTTP Request"].json["access_token"] }}Refresh Token: {{ $json.refresh_token }} or {{ $node["HTTP Request"].json["refresh_token"] }}

[Jonathan_Liu]

concept sounds nice.
how to implement via n8n salesforce? i dont know where to add Access Token: {{ $json.access_token }}

new n8n salesforce tool

select cred

connect my account opens up the salesforce sign in page. which is not what i want.

Instead of generating jwt by yourself, salesforce already handled it by using Oauth2 JWT, see below, it more easy-to-use authentication instead of defining jwt by yourself.
