Setup:

You need to get the apikey form the bot before using the API:

  1. Add the new bot phone number +34 623 78 64 49 into your Phone Contacts. (Name it as you wish)
  2. Send this message "I allow callmebot to send me messages" to the new Contact created (using WhatsApp of course)
  3. Wait until you receive the message "API Activated for your phone number. Your APIKEY is 123123" from the bot.
    Note: If you don't receive the ApiKey in 2 minutes, please try again after 24hs.
  4. The WhatsApp message from the bot will contain the same apikey that you had before. So you don't need to update the code on your side.

You can continue sending messages using the API after receiving the confirmation.

Example:
58

5. Enjoy
