HTTP API overview

Last Updated: May 24, 2020

Time Series Database (TSDB) instances allow you to write and query data by using HTTP.

TSDB provides an HTTP API to facilitate integration with external systems. You can call API operations to use almost all TSDB features, for example, querying time series data, managing metadata, and storing data points. The HTTP API for TSDB is RESTful in nature. The HTTP API also provides alternative access methods because not all clients strictly comply with the REST protocol. JSON is used as the default format for data exchange. Standard HTTP status codes are used for all the responses, and errors are returned in a specific format.

The following table lists all the TSDB API endpoints that you can use to read, write, and manage data. For more information about each endpoint, click the link in the Description column to view the corresponding topic.
