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 with a detailed documentation.
Description
SendPulse’s REST API service works over the HTTP protocol and is essentially a set of methods that are used to perform requests and receive responses for each operation.
All answers return in the form of JSON structures.
The rate limit is 10 requests per second.
SendPulse API libraries
The latest versions of SendPulse API client libraries are available at GitHub.
API endpoint
All references to API requests in this document include the root URL:
Authorization
Authorization process requires a personal key signing each further API request.
The necessary parameters to obtain the key can be found in the private account settings page found on the following URL
https://login.sendpulse.com/settings in the API tab.
The following parameters are used:
| grant_type | has to be equal to client_credentials |
| client_id | your ID (API) |
| client_secret | your secret (API) |
To get the key you have to send a POST request to:
| https://api.sendpulse.com/oauth/access_token |
A sample response: The resulting key is valid for 1 hour and does not require additional requests for each operation. Request for a new key must be sent before the current key expires.
