TProTool — WhatsApp API for sending messages
A platform to link a WhatsApp session, send text and media, and receive its events. Each session has its own key. Details are in the docs.
Link WhatsApp
You link your number to a session by scanning a QR code in WhatsApp (Linked devices). Sending then goes out from that number through the API. The key works for its own session only.
How to start
Register, verify your mobile, create a session, scan the QR code, then create the send key on the session page.
Sending and tracking
Send a text message, a file, or a batch of up to 50 messages. The request is queued and answered immediately, and you track status on the messages page or by query. There is a short wait between one message and the next so the session is not closed.
Events
When a webhook is enabled, your URL receives a short event: session status, messages, and delivery updates. You can sign the request with a secret from the session settings.
