Free API to Send Whatsapp Messages

July 12, 2021 Uncategorized No comments

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.

[phone_number]: Is your phone number asociated to your WhatsApp including the country code. (Ex: +34 123 123 123).
[text]: Message to send (urlencoded). You can use this online converter to encode the message. (i.e. %20 for space, %0A for new lines). WhatsApp formatting characters are allowed (i.e “*” for bold, etc.). Check here how to include emoticons in the message .
[your_apikey]: The apikey that you received during the activation process (step 4-5 above)

Example:

https://api.callmebot.com/whatsapp.php?phone=+34123123123&text=This+is+a+test+from+CallMeBot&apikey=1234567890

If you have problems building the URL, you can try the Web Browser assistant to test the API.

As this API is in beta testing, the messages can be delayed up to 1 minute.
