Before you start.
Do I need my own phone?
Yes. You link a WhatsApp account already registered on your phone. OswiLink does not create the account or replace that registration.
What happens when my trial ends?
New sends are blocked and the connection stops. There are no automatic charges. Monthly subscriptions and payments are not active yet.
Are my conversations stored?
We are not a permanent archive. Content and events are kept temporarily for about 24 hours; technical message metadata for up to 30 days. Connection credentials are stored separately. Read the details.
Is this the official WhatsApp API?
No. The connection uses Baileys, an unofficial library. Provider disconnections or restrictions may occur. This pilot does not offer guaranteed uptime.
