I really like how Qmize (Official WhatsApp API) connects me with a large number of audiences, improves customer engagement through chatbots, and integrates my business system into their platform. Their support is impressive, with a dedicated person assigned to my company who connects instantly to resolve any issues, no matter how small. They handle the support through calls or meetings, and the issues are resolved immediately. I'm also very satisfied with their service as we used Qmize for the first time. The initial setup was easy; we just shared the FBM access, a number, and the OTP, and their team took care of everything else. Review collected by and hosted on G2.com.
Contact deletion option should be there in the API. Review collected by and hosted on G2.com.
