FAQs
What are the best practices for avoiding failures when creating WhatsApp groups via API?
To minimize failures when creating WhatsApp groups, start with only one or two participants and only add a few at a time. After the group is successfully created, gradually add more members, limiting additions to 10 participants simultaneously using the ‘Add participants’ API endpoint. This approach helps prevent issues, especially if your WhatsApp number is already associated with many active chats.
