Voxology’s Programmable SMS gives developers the keys to one of the industry’s largest and most reliable cloud communications platforms in a powerful API. The service allows you to programmatically send and receive both long code and short code SMS messages, read logs, and manage phone numbers.
The Voxology REST API enables you to send SMS messages and read logs. It also allows you to manage your account, applications, phone numbers, and callback configurations.
You can view a full list of Voxology’s REST API Methods on the API Reference.
curl -X POST \
https://api.voxolo.gy/v1/Messages \
-H 'Content-Type: application/json' \

"api_no": "+19495551212",
"caller_no": "+17145551212",
"text_message": "Hello, World!"
}
}'Voxology’s Callbacks allow you to receive inbound SMS messages. When a message is sent to an SMS enabled Voxology phone number, Voxology will send a callback containing the text message to the URL that you designate. Unlike Programmable Voice, Voxology does not expect to receive a response to Programmable Messaging callbacks of “type”: “sms”.

}This tutorial is a step-by-step guide to setting up an SMS enabled number which receives a text message.
To receive an inbound phone call, you need to search for an available phone number, provision it, and assign it to CallFlows, using either the Portal or our REST API (instructions below).
To search for an available phone number, go to List Inbound Available Phone Numbers and prepare your query request. For SMS enabled numbers, make sure to set capabilities=sms (see example below)
curl -X GET \
'https://api.voxolo.gy/v1/PhoneNumbers/Available?capabilities=voice,sms&search_by=prefixes&search_on=INSERT_YOUR_AREA_CODE' \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/json' \
-H 'X-Api-Key: YOUR_API_KEY'Once you have made your GET request, select a phone number from the list of results and 'copy' it. To provision the number, go to Provision Phone Numbers, ‘paste’ the number into your request body and assign it to CallFlows (see example below).
curl -X POST \
https://api.voxolo.gy/v1/PhoneNumbers/CallFlows \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-H 'x-api-key: YOUR_API_KEY' \
-d '{
"phone_numbers": [
{
"no": "PASTE_YOUR_VOXOLOGY_NUMBER_HERE"
}
]
}'Now that you have provisioned your new SMS enabled phone number, it is time to configure the callback settings.
To quickly test inbound SMS, set your callback configuration URL to the Webhook.site service following these steps:
curl -X PUT \
'https://api.voxolo.gy/v1/CallFlows/Configurations/PhoneNumbers/PASTE_YOUR_VOXOLOGY_NUMBER_HERE_URL_ENCODED' \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-H 'x-api-key: YOUR_API_KEY' \
-d '{
"callback": {
"method": "GET",
"url": "YOUR_UNIQUE_URL",
"content_type": "application/json"
}
}'Now you can text “Hello, World!” to the new phone number that you configured. If all went well, you should be able to refresh your RequestBin page and see the text message.
Congratulations! You are now ready to send a text message from the number that you just programmed.
This tutorial is a step-by-step guide for generating an SMS to a call phone number using the REST API.
To send a text message from the number that you programmed above, you will use the Send SMS method and copy/paste the following body:
curl --X POST \
https://api.voxolo.gy/v1/Messages \
-H 'Content-Type: application/json' \
-H 'X-API-Key: YOUR_API_KEY' \
-H 'Cache-Control: no-cache' \
-d '{
"api_no": "PASTE_YOUR_VOXOLOGY_NUMBER_HERE",
"caller_no": "TO_NUMBER",
"text_message": "Hello, World!"
}'Once you have prepared your request body, send it. If successful, you should receive the “Hello, World!” text message.
Congratulations! You can now send SMS messages from your Voxology phone numbers. Next, you can point your number to a URL on your own server and start building intelligent SMS messaging into your application.
