InfluxDB OSS v2

Use Postman with the InfluxDB API

This page documents an earlier version of InfluxDB OSS. InfluxDB 3 Core is the latest stable version.

Use Postman, a popular tool for exploring APIs, to interact with the InfluxDB API.

Install Postman

Download Postman from the official downloads page.

Or to install with Homebrew on macOS, run the following command:

brew install --cask postman

Send authenticated API requests with Postman

All requests to the InfluxDB v2 API must include an InfluxDB API token.

Authenticate with a username and password

If you need to send a username and password (Authorization: Basic) to the InfluxDB 1.x compatibility API, see how to authenticate with a username and password scheme.

To configure Postman to send an InfluxDB API token with the Authorization: Token HTTP header, do the following:

  1. If you have not already, create a token.
  2. In the Postman Authorization tab, select API Key in the Type dropdown.
  3. For Key, enter Authorization.
  4. For Value, enter Token INFLUX_API_TOKEN, replacing INFLUX_API_TOKEN with the token generated in step 1.
  5. Ensure that the Add to option is set to Header.

Test authentication credentials

To test the authentication, in Postman, enter your InfluxDB API /api/v2/ root endpoint URL and click Send.

InfluxDB v2 API root endpoint
http://localhost:8086/api/v2

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
