SendPulse Service REST API
Introduction
Our API interface is used to integrate SendPulse’s distribution service capabilities with client’s personal projects. The API is designed for developers and is accompanied by detailed documentation.
Description
SendPulse’s REST API works over the HTTPS protocol and is essentially a set of methods used to perform requests and receive responses for each operation. All answers return in the form of JSON structures.
The request limit is 10 requests per second.
Cross Domain Queries (jQuery Ajax Example) are not allowed.

Base URL
All references to API requests in this document include the root URL:
https://api.sendpulse.com |
Authorization
The authorization process requires a personal key for signing each further API request.
The necessary parameters to obtain a key can be found in the private account settings page found on the following URL in the API tab.
To get the key you have to send a POST request to:
https://api.sendpulse.com/oauth/access_token |
Request parameters:
Parameter | Type | Description | |
grant_type | string | Has to be equal to client_credentials |
required |
client_id | string | Your ID | required |
client_secret | string | Your Secret | required |
Request example:
{
"grant_type":"client_credentials",
"client_id":"237b4af9c99d0f89bdbd876dcd5a0000",
"client_secret":"a99e7d506d3701c5c04de3db1913eeee"
}
If request is successful, you will receive a response:
{
"access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImp0aSI6IjI5NTQ4NDVjZWJlZjg5Nzk0YmYzMzk4ZDdiNTQ3OTA2MWUzNDQ2N2I5NTUwMmFlNzE1YmViZmU4MDBmNTMxMjIxMTU2MTcyOWM2MjI5NGRjIn0.eyJhdWQiOiIyMzdiNGFmOWM5OWQwZjg5YmRiZDg3NmRjZDVhMDE3ZiIsImp0aSI6IjI5NTQ4NDVjZWJlZjg5Nzk0YmYzMzk4ZDdiNTQ3OTA2MWUzNDQ2N2I5NTUwMmFlNzE1YmViZmU4MDBmNTMxMjIxMTU2MTcyOWM2MjI5NGRjIiwiaWF0IjaaNjI0NTI0OTA0LCJuYmYiOjE2MjQ1MjQ5MDQsImV4cCI6MTYyNDUyODUwNCwic3ViIjoiIiwic2NvcGVzIjpbXSwidXNlciI6eyJpZCI6Njc0MTgwNCwiZ3JvdXBfaWQiOm51bGwsInBhcmVudF9pZCI6bnVsbCwiYXJlYSI6InJlc3QifX0.jiP3Sv7IF1mHGmW0oGIrPAw0oOiIEnC8Tb6wlWu5eVM2UrHL6RZsDlIslLSQNEvL_e50nDlgtgyfX5Qty4qlQ4XyW53FAgjwHbyQG7DJ6iVRAtVBtFNbkFVNbHvKw8zQy7WyxhICpAF8zdF8-gBHBnzuMhKSnASYEosJ9IAPqUkxQXrd8LpUSk-etzjEqcpMkbGj2M7Y0OxO4_BfRhVNU6ZcbiawD09m0A9uWoSnoZKxXw0o64PE3anJta6lFns5SDuyeGxanOtuZSS5I3umI2OOnUVzNG9_5WjCe6LPVQLAPAPt0m8S5WkI35_jCJ0A-gDBBdsgnUudGCvsDcgEog",

The resulting key is valid for 1 hour and does not require additional requests for each operation. A request for a new key must be sent before the current key expires.
The key code (token) must be sent in the header of all requests except for requests for getting the token itself (when the key is not required).
Request limits
There are limits and quotas on SendPulse API requests to protect the system from receiving more data than it can handle and ensure an equitable distribution of the system resources. API limits per minute and per day depend on the category of your selected pricing plan
General quota limits
The following quotas apply to sending API requests:
Pricing Plan Category | Requests Per Minute | Requests Per Day | Pricing Plan in Services |
Free | 1,000 | 500,000 | All free pricing plans in the SMTP, Landing Page, Push, and Chatbot services |
Standard | 2,000 | 1 million | All pricing plans between "Free" and "Enterprise" |
Enterprise | 3,000 | 3 millions | For Email and Landing Pages services with the “Enterprise” category and for the Push service with the “Pro” category and with more than 50,000 subscribers;
for the Chatbot service with the “Pro” category with more than 5,000 subscribers; |
Exceeding quota limits
If you exceed this quota, the API returns the following error:
429 Too many requests
To be able to send more requests, you need to upgrade your current pricing plan.
