Hi friend, did you get any answers?
Hi @brunmargofc,
Thank you for reaching out.
The SalesForce API Connector Plugin allows connecting to your own Salesforce account and managing leads, contacts, and opportunities into your Bubble app.
Unfortunately, it’s not possible to connect multiple salesforce accounts into one Bubble app using this plugin due to each integration requires a unique API key and you will get an Authorization error when trying to connect to a different account without changing the correct API keys inside your Bubble app.
Should you need any further information, please do not hesitate to contact us. We’ll be glad to help. 
Best regards,
Zeroqode Support Team.
