Getting Started with Axiom API

Axiom understands your resources and provides an API to ingest structured data logs, handle queries, and manage your deployments. This REST-style API uses JSON for serialization and gives you complete control over the entire Axiom platform.

This page covers the basics for interacting with the Axiom API, instructions for ingesting data, and notes on some commonly used endpoints.

You can use the API commands with curl by providing your Access Token.

API Basics

All our endpoints live under the url and follow the REST architectural style.

Here’s an example in curl:

curl -X 'POST' '$DATASET_NAME/ingest' \
  -H 'Authorization: Bearer $API_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{ "axiom": "logging"}'

Content Type

All requests must be encoded as JSON with the Content-Type header set to application/json. If not otherwise specified, responses from the Axiom API, including errors, are encoded exclusively as JSON as well.


Datasets are required to send, query, and retrieve requests. Datasets are a collection of similar events. When data is sent to Axiom, it is stored in a dataset.

You will need to create or use an existing Dataset to get started with Axiom REST API.

See Creating a Dataset to get started.


Requests to the Axiom API must provide an API token through the Authorization header:

Authorization: Bearer <$API_TOKEN or $PERSONAL_TOKEN>

The Authorization header with an access token:

API Tokens can be created and managed from Settings --> API Tokens on Axiom UI.

See Access Tokens for more detail.

Organization ID

Organization identification is required for you to send requests using Personal Tokens.

The org id credentials can be obtained on the Settings page.


The org id can also be obtained from the url of your Axiom deployment.

In your Axiom deployment url, the credential axiom-wt8j is the organization ID.

Failed Authentication

If authentication is unsuccessful for a request, the error status code 403 is returned.


Below is a list of the types of data used within the Axiom API:

IDA unique value used to identify resources."io12h34io1h24i"
StringA sequence of characters used to represent text."string value"
BooleanA type of two possible values representing true or false.true
IntegerA number without decimals.4567
FloatA number with decimals.15.67
MapA data structure with a list of values assigned to a unique key.{ "key": "value" }
ListA data structure with only a list of values separated by a comma.["value", 4567, 45.67]
