An n8n workflow can send an SMS or make a phone call through SMSEagle, your own hardware SMS gateway. Replies can come back into n8n and start the next step.
n8n sends SMS with its standard HTTP Request node, so you only enter the SMSEagle address and API key.
SMSEagle can pass incoming SMS to an n8n webhook, so a reply can start the next step of your automation.
SMSEagle sends SMS through a regular SIM card, so you only pay for your mobile plan.
Add a Core > HTTP Request node to the workflow, set Method to POST, and point the URL at your SMSEagle device’s API v2 endpoint (for example /api/v2/messages/sms for SMS).
Under Authentication, choose Generic Credential Type > Header Auth, and create a credential holding the access token generated on your SMSEagle device.
SMSEagle delivers the alert over its own cellular connection, not through a third-party service, as an SMS or a phone call to the recipient’s phone.
No dedicated SMSEagle node to install. A single HTTP Request node with a Header Auth credential is enough to send SMS, wake-up calls, or text-to-speech voice calls from any n8n workflow in 10-15 minutes.
SMSEagle sends n8n alerts as an SMS, a ring-only call or a call that reads the alert aloud, all from a single device.
On devices with two SIM cards from different operators, SMSEagle switches to the second one when the first operator’s network is down.
Two SMSEagle devices can work as an HA cluster: if one fails, the other takes over sending.
SMSEagle API will be used to call SMS requests from n8n.
2. Configuring new HTTP Request Node
a) Method – select POST
b) In the URL field paste: https://smseagle-ip/api/v2/messages/sms
(where smseagle-ip is an actual IP address of your own SMSEagle device)
c) In the Authentication select: Generic Credential Type
d) In the Genering Auth Type select: Header Auth
e) In the Header Auth choose: Create new credential, and in new window fill the fields:
– name: access-token
– value: paste the access token from the previously created user
f) Save
g) click on toggle at Send Body, choose Body Content Type: JSON
h) In the Specify Body select: Using JSON
{
"to":
[
"+48123456789"
],
"text": "This is SMS message body."
}You can use a phone number (for example +48111222333) or a group defined in SMSEagle Phonebook (for example admin-group) as recipient.
3. Test
It’s possible to test the integration – click on Test step button, on the right panel you’ll see the SMSEagle API status output.
In the Specify Body select: Using JSON
{
"to": ["+48123456789"],
"duration": 30
}You can use a phone number (for example +48111222333) as recipient.
In the Specify Body select: Using JSON
{ "to": ["+48111222333"],
"voice_id": 2,
"text": "Example voice alert text"
}SMSEagle is a hardware & software solution that guarantees a swift delivery of your messages to designated recipients, whether it’s for notifications, alerts, or important updates.
After registering to a demo you get a remote access to our physical device NXS-9750.
