Keep in mind logging in via login.salesforce.com isn’t exactly the same when logging in via Snaplogic. Since Snaplogic is hitting the Salesforce REST API. Depends on your Salesforce security settings, you might have to pass a security token with your credentials. In case you don’t know your security token.
name > Setup > Personal Setup > My Personal Information > Reset My Security Token.
OR
You can whitelist your cloudplex or groundplex IP to omit the need to pass the security token:
- Go to profile detail page.(User can see ‘Login IP Ranges’ related list on Profile detail page.)
- Go to Login IP Ranges related list of profile.
- Click New button(To Enter the IP Range)
- Enter IP Range:
Another possibility is that your profile doesn’t have API enable checked.
An easy way to validate your access is to use a SOQL client like SoqlXplorer (Mac) or ForceExplorer (PC) to test your API access.
