You may send the first SMS message for free using textbelt as your API key.

We’ll essentially make an HTTP POST request to the SMS service provider’s API to send the text message.Īnd this request will be different for each SMS service depending on their API endpoints. Next, proceed to the Tasks screen and choose Webhooks from the list of services.

You can thus build workflows that send text reminders when the invoices are due. The Document Studio add-on helps you automatically send text messages when a new Google Form is submitted or when new rows are added to Google Sheets. just a little more work to send a message).Send personalized text messages in bulk from Google Sheets using your favorite SMS service So of course there's a catch when things are free (i.e. You just need to know the gateway (meaning you need to know the carrier). For example, you can find a carrier's email-to-SMS gateway so that you can send SMS to recipient from your email account, see or. Unfortunately, I believe that lookup process isn't really available for free, hence free services like Textbelt probably resort to alternate options. to find out which phone carrier the recipient is on based on the phone number and then passes it to the SMS gateway of the recipient's carrier. The plan provider receives your SMS to recipient's phone number and does a lookup via some directory/algorithm, etc. For this to work, the carrier needs to offer an email-to-SMS gateway for us to send the message through via an email like of it this way, basically, you pay (as part of your phone service plan) to send SMS to recipient from your phone. It goes to the carrier's mail server and gets translated to an SMS message that then routes to the phone. The way the service works for sending SMS text messages is by routing the message by email. The current supported list of carriers can be found at. Bear in mind some of your support issues may be specific to the Textbelt API rather than the extension, so then I may not be able to help you in that case, contact the API developer at instead. You can try to get support at the Github site link above.
#Textbelt code
Source code for the extension will be available at Well, here's an extension for the everyday folks to use it, no scripting/programming needed. I built this extension since the service provider is only an API (for developers). But you can put that inside the SMS message if needed.

Unfortunately, this service doesn't offer option to supply a reply number or address for recipient to reply to. SMS support limited to carriers noted at. There is some limits on the number of messages you can send in a day and within a short period of time.
#Textbelt registration
Built against the free & cool API, this extension allows you to send SMS text messages for free, without requiring any registration nor entering CAPTCHA codes.
