Hi!
I'm trying to access Salesforce content from an external site. For this I want to use the APIs provided by Salesforce.

From Postman it works OK and I do the following:

I have created a connected app in salesforce with this settings:
- Available OAuth Scopes -> full access
- OAuth Policies -> IP Relaxation -> Relax IP restrictions
- OAuth Policies -> Permited Users -> All users may self-authorize

From Postman:
- I do a post request with the following body:


- In hit this endpoint 'https://test.salesforce.com/services/oauth2/token' and I get a good response



With this access token I can build another request and I get my resource from salesforce until here everything ok...

My problem is when I try to get the access token from the site's javascript. My code:



I get this error:


To resolve this issue I have added the site from which I launch the requests to the salesforce CORS whitelist and I have enabled the Enable CORS for OAuth endpoints but nothing seems to change.

With the access token obtained via Postman I can do the following request from my site and it works:



This SOQL request send me a JSON with a good response.

Therefore, to solve my problem I would need to obtain this access token from my site in order to later build the following request .
Anybody knows how can I resolve this issue?

Thank you very much in advance,
Best regards
