The Toloka API is designed for creating tasks in Toloka and getting users' responses. You can:
Set up a project with a description of task settings (visual appearance, input fields, and so on).;
Create a pool of tasks.
Define the logic for selecting users who will complete the tasks.
Import data for tasks (image URLs, text, and so on).;
Requests are sent to the Toloka API over the HTTPS protocol. The service returns data in JSON format.
For debugging tasks, Toloka provides a testing environment — the sandbox. Once you have tested the settings, you can use the project and pool in the production version of Toloka (the only thing you need to change is the request URL and the OAuth token).
