FAQ

Are the SDKs required?

No, but they are highly recommended.

OneSignal provides the Create user, Create subscription, Update user, and Update subscription APIs for creating and updating user and subscription data along with the Create notification API sending push notifications, email, and SMS messages. The OneSignal SDK is required if you plan to use the In-App Messaging functionality.

Server API-only integrations are possible but not recommended because push notifications have several different requirements that our SDK handles for you, including:

• obtaining push tokens across Android, iOS, Huawei, and Web Browsers
• verifying subscription status, prompting, and opting-in users
• displaying the notification and handling the payload

For example, the APNS push payload has a standardized format but FCM does not. Setting up both would need additional dev work to handle notifications client side. OneSignal's Push Payload contains a "custom" key with a nested "i" value when sent through our system. Our SDK checks this value to handle the push notification. See OneSignal's Custom Push Payload here and our article on Build vs Buy for more details.
