I want to send Whatsapp transactional messages to users and for which I am opting in them via Gupshup's WhatsApp API. This is the API that I am using:
When I go to Opt In users screen, I am able to find users who have opted in via this API. Refer below image for it:
The issue is when I try to send messages to these users (opt-in via Upload), messages failed citing the reason that user is not opted in. Refer below image for it:
Users who have opted-in via API seem to have two different status at the same time and I am not able to find out why. Do you know what may be causing this strange issue?
