Introduction

Sendoso’s Marketplace and SmartSend API allows you to send physical gifts and direct mail to your customers, leads, and employees. With our API, you can automate the sending of gifts and direct mail to your recipients.

With the power of SmartSend, you can have Sendoso decide the best gift to send based on the recipient’s interests and preferences.

To get started, you will first need to sign up for a Sendoso account and obtain your API key. Once you have your API key, you can begin making API calls to access and manipulate data within your Sendoso account.

Our API is organized around REST principles and is designed to have predictable, resource-oriented URLs and to use HTTP response codes to indicate API errors. We support both GET and POST requests, and all data is sent and received in JSON format.

If you have any questions or need further assistance, please contact our support team at developers@sendoso.com.
