Termii Bulk SMS API: Send SMS to up to 10k phone numbers with a single API request

It’s a perfect time! We are excited to announce our BULK SMS API — an addition to the Switch feature that simplifies and improves the way businesses and developers can build bulk SMS in their web/applications this sales period (and of course, beyond).

Why is this an exciting update?

Before now, if developers needed to communicate with many users via Switch, they had to first;

  1. Use the send message API, which has a limit of 100 phone numbers and could only send a message to a maximum of 100 phone numbers in one single API call.
  2. the Campaign API, which took a long process of creating a phone book, uploading contacts.

At this moment, developers and businesses can send bulk SMS to up to 10,000 phone numbers in one single API call via Termii’s Bulk SMS API.

Termii Bulk SMS API is applicable if you need to:

  • Send reliable and timely notifications. Making sure your users/subscribers don’t miss out on important and urgent information just got easier. You can use a single API request to send a bulk message to your customers.
  • Communicate marketing/promotional updates. With the Termii Bulk SMS API, businesses can seamlessly make a single request that notifies a set of phone numbers

What does this mean for developers?

Easier application — One API request to send up to 10,000 SMS messages

How it Works…

Create a JSON payload that takes:

  • An array of phone numbers between 1 and 10,000 in the to field.
  • Your message in the sms field in and then pass.
  • Set your sender-id as from and then other necessary fields as stated in the documentation.

When you are ready, fire up the request and our system take it from there.

Sample JSON request

{
"to": ["23490555546","23423490126999","23490555546"],
"from": "talert",
"sms": "Hi there, testing Termii",
"type": "plain",
"channel": "generic",
"api_key": "Your API Key",
}

Sample Response

{
"code": "ok",
"message_id": "9122821270554876574",
"message": "Successfully Sent",
"balance": 9,
"user": "Peter Mcleish"
}

Check the API documentation for more.

Please note: We strongly recommend the bulk SMS API for developers/businesses sending a message to multiple phone numbers, if otherwise, the send API is most appropriate.

Now that you know how to use Termii’s Bulk SMS API, you can enhance your company’s marketing and branding by reaching out to a large set of your customers with those special discount coupons, holiday deals, and updates from your business with a single API request.
