WhatsApp provides two ways for your iPhone app to interact with WhatsApp:
If your application would like to open a WhatsApp chat with a specific contact, you can use our custom URL scheme to do so. Opening whatsapp:// followed by one of the following parameters, will open WhatsApp and perform a custom action.
send
URL | Parameters | Opens |
---|---|---|
app |
— | The WhatsApp Messenger application |
— | New chat composer | |
abid |
Address book ID of contact to start a chat with. If contact with this ID has only one whatsapp-able phone number, application will open a conversation with that contact. If contact with this ID has more than one whatsapp-able phone numbers, application will present a menu with all phone numbers available for chat. If contact has no whatsapp-able phone numbers, or contact with this ID does not exist, or this parameter is missing, application will present contact picker listing all contacts available for chat via WhatsApp. | |
text |
If present, this text will be pre-filled into message text input field on a conversation screen. |
The Objective-C call to open one of these URLs is as follows:
NSURL *whatsappURL = [NSURL :@"whatsapp://send?text=Hello%2C%20World!"];
if ([[UIApplication ] : whatsappURL]) {
[[UIApplication ] : whatsappURL];
}
If your application creates photos, videos or audio notes and you’d like your users to share these media using WhatsApp, you can use the Document Interaction API to send your media to your WhatsApp contacts and groups.
WhatsApp Messenger can handle various types of media:
Alternatively, if you want to show only WhatsApp in the application list (instead of WhatsApp plus any other public/*-conforming apps) you can specify a file of one of aforementioned types saved with the extension that is exclusive to WhatsApp:
When triggered, WhatsApp will immediately present the user with the contact/group picker screen. The media will be automatically sent to a selected contact/group.
See the Apple documentation articles: Previewing and Opening Files and the UIDocumentInteractionController Class Reference for more information.
