Free API to Send Whatsapp Messages
Note: The Free API to Send Whatsapp Messages is only for personal use.
CallMeBot can now send WhatsApp Text Messages! Super easy using one simple API call.
Setup:
You need to get the apikey form the bot before using the API:
- Add the phone number +34 698 28 89 73 into your Phone Contacts. (Name it it as you wish)
- Send this message “I allow callmebot to send me messages“ to the new Contact created (using WhatsApp of course)
- Wait until you receive the message “API Activated for your phone number. Your APIKEY is 123123” from the bot. As this is still in beta testing, the activation can take up to 2 minutes.
- The WhatsApp message from the bot will contain the apikey needed to send messages using the API.
You can send text messages using the API after receiving the confirmation.
