Forming a request

How you send requests to the Streaming Writer API will vary depending on the client or language you’re using. But the API still has behavior and expectations that is common across all clients.


The examples in this section show how to use the popular curl command line tool.

Before you begin

Endpoint URLs

The Streaming Writer API is available on a per-workspace basis, so the subdomain is based on a combination of your organization and workspace names. See the Swagger documentation to find out how to get the exact hostname required. It will be in this format:


So your final endpoint URL will look something like:


Endpoints in this API use the POST and PUT methods. Ensure your HTTP client sends the correct request method.

Using curl, you can specify the request method with the -X <POST|PUT> flag, for example:

curl -X PUT ...


For most methods, you’ll need to send a JSON object containing supported parameters. You’ll also need to set the appropriate content type for the payload you’re sending:

curl -H "Content-Type: application/json" ...


You must specify the content type of your payload. Failing to include this header will result in a 415 UNSUPPORTED MEDIA TYPE status code.

You can send data using the curl flag -d. This should be followed by either a string of JSON data, or a string starting with the @ symbol, followed by a filename containing the JSON data.

curl -d '{"key": "value"}' ...
curl -d "@data.json" ...


By default, -d will send a POST request, so -X POST becomes unnecessary.

Complete curl example

You should structure most of your requests to the API around this pattern:

curl -H "Authorization: ${token}" \
     -H "Content-Type: application/json" \
     -d "@data.json" \
