Postman is a popular tool for exploring APIs. Use it 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 cask install postman

Send authenticated API requests with Postman

All requests to the InfluxDB API must be authenticated. Postman lets you configure the headers and body of HTTP requests.

Use the Authorization tab in Postman to include the credentials required when interacting with the InfluxDB API.

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

To test the authentication, enter the /health endpoint of a local or Cloud instance of InfluxDB into the address bar (for example, http://localhost:9999/api/v2/health or https://us-west-2-1.aws.cloud2.influxdata.com/api/v2/health) and then click Send.
