The API in Salesforce is now enabled for the modified profile. All users with this profile now have API enabled permissions.

***

***Optional:*** If your sync includes the ContentDocumentLink object (used for Salesforce Files / attachments), also enable the Query All Files permission in the same permission set. This only works for custom profiles, salesforce standard profiles do not allow you to turn enable this permission.\
\
5\. In your custom profile scroll down to *Administrative Permissions* section and enable *Query all data*
