Send email campaigns, SMS, and web-push notifications and manage mailing lists via the SendPulse API.

SendPulse

Send email campaigns, SMS, and manage mailing lists from InTouch via the SendPulse REST API.

Base URL: https://api.sendpulse.com
Auth: Bearer token (static API key or OAuth2 client credentials — see below)
Credential storage: none — credentialBased: false; the key is passed inline

What it does

One tool, four operations covering the most common SendPulse workflows:

operation	Method & endpoint	Purpose
`list-books`	`GET /addressbooks`	List all mailing lists with their IDs and contact counts
`add-emails`	`POST /addressbooks/{bookId}/emails`	Add one or more subscribers to a mailing list
`send-campaign`	`POST /campaigns`	Create and send (or schedule) an email campaign to a list
`send-sms`	`POST /sms/send`	Send an SMS to one or more phone numbers

Every call returns:

{ "result": "<SendPulse response body>", "status": "200" }

result is the raw SendPulse response (a JSON string). Only transport failures (DNS error, timeout) mark the step FAILED; 4xx/5xx errors surface in status and result so you can branch on them downstream.

apiKey setup

SendPulse supports two credential forms; both work via the apiKey input:

Option 1 — Static API key (simpler, recommended): 1. Log in to SendPulse and go to Settings -> API. 2. Under API keys, click Add API key, copy the key. 3. Pass the key directly as apiKey.

Option 2 — OAuth2 client credentials: 1. Under Settings -> API, find your Client ID and Client Secret. 2. Pass them joined with a colon: apiKey = "your_client_id:your_client_secret". 3. The tool detects the colon, calls POST /oauth/access_token (grant_type=client_credentials), and uses the resulting access_token (valid for 1 hour) for the API call.

Operations

list-books

Returns the full list of mailing lists (address books) in the account. No extra inputs required.

{ "apiKey": "YOUR_KEY", "operation": "list-books" }

Sample result fragment:

[{"id": 987654, "name": "Newsletter 2026", "all_email_qty": 1200}, ...]

add-emails

Adds subscribers to a mailing list. bookId is the numeric ID from list-books.

Plain comma-separated addresses:

{
  "apiKey": "YOUR_KEY",
  "operation": "add-emails",
  "bookId": "987654",
  "emails": "[email protected], [email protected]"
}

With merge variables (JSON array):

{
  "apiKey": "YOUR_KEY",
  "operation": "add-emails",
  "bookId": "987654",
  "emails": "[{\"email\":\"[email protected]\",\"variables\":{\"Name\":\"Alice\",\"Phone\":\"+1555\"}}]"
}

send-campaign

Creates and immediately dispatches an email campaign to a mailing list. The senderEmail must be a verified sender in your SendPulse account. The HTML body is automatically Base64-encoded before sending.

{
  "apiKey": "YOUR_KEY",
  "operation": "send-campaign",
  "bookId": "987654",
  "senderName": "Acme Corp",
  "senderEmail": "[email protected]",
  "subject": "June product update",
  "bodyHtml": "<h1>Hello!</h1><p>Here is what is new this month.</p>"
}

Sample result: {"id": 112233, "status": 1, "all_email_qty": 1200, ...}

send-sms

Sends an SMS to one or more international phone numbers. smsSender must be 11 alphanumeric characters or fewer (country-dependent).

{
  "apiKey": "YOUR_KEY",
  "operation": "send-sms",
  "smsSender": "AcmeCorp",
  "smsPhones": "+15551234567, +447911123456",
  "smsBody": "Your order has shipped! Track at acme.com/track"
}

SMS delivery requires an active SendPulse SMS balance and a registered sender name in the countries you are targeting.
