What OAuth means
OAuth is a standard authorization framework that lets one party grant another limited access to its account without handing over a password. On the WhatsApp Business Platform, Meta uses OAuth so a business can authorise a Business Solution Provider (BSP) like InfiQ to act on its WhatsApp Business Account — sending messages, managing templates — through scoped, revocable access rather than shared credentials.
In practice this happens during Embedded Signup: the business logs in with Meta, sees exactly what it is granting, and approves. Meta issues an access token to the partner behind the scenes; the business's password never reaches the partner, and access can be withdrawn later.
For developers, OAuth is why access tokens exist and why they can be scoped and rotated. InfiQ handles the OAuth exchange during onboarding so customers get connected securely without managing the token dance themselves.
