Hello!
Do you know of any advanced (email) marketing automation tools (such as Active Campaign) that support API integration using authentication methods such as OAuth or Personal Access Tokens?
Ultimately, I am left with integration via an integrator like Zapier or Make, but due to the complex database and integration options, I am particularly keen on some kind of direct connection.
The business falls into the wellness category - appointment making, reminders, loyalisation etc.
Thanks in advance for your guidance!
