Hi, 

I am using zoho invoice for my two applications. And I am using zoho API in my two applications too.

I Have created two organizations with my zoho account and I can able to access zoho invoice through zoho UI.

My doubt is could I  able to use two organisations for my two applications simultaneously using zoho invoice api with one zoho account(considering one account charges of plan for invoice), or It's not possible to use simultaneously with one account.

Thanks.
