The Harness Software Delivery Platform uses OpenAPI Specification v3.0. Harness constantly improves these APIs. Please be aware that some improvements could cause breaking changes.
The Harness API allows you to integrate and use all the services and modules we provide on the Harness Platform. If you use client-side SDKs, Harness functionality can be integrated with your client-side automation, helping you reduce manual efforts and deploy code faster.
The Harness API is a RESTful API that uses standard HTTP verbs. You can send requests in JSON, YAML, or form-data format. The format of the response matches the format of your request. You must send a single request at a time and ensure that you include your authentication key. For more information about this, go to Authentication.
Before you start integrating, get to know our API better by reading the following topics:
The methods you need to integrate with depend on the functionality you want to use. Work with your Harness Solutions Engineer to determine which methods you need.
To authenticate with the Harness API, you need to:
x-api-keyheader in each request.
To generate an API token, complete the following steps:
Important: Make sure to save your token securely. Harness does not store the API token for future reference, so make sure to save your token securely before you leave the page.
Send the token you created in the Harness Platform in the x-api-key header. For example:
The structure for each request and response is outlined in the API documentation. We have examples in JSON and YAML for every request and response. You can use our online editor to test the examples.
|identifier||string||none||URL-friendly version of the name, used to identify a resource within it's scope and so needs to be unique within the scope.|
|name||string||none||Human-friendly name for the resource.|
|org||string||none||Limit to provided org identifiers.|
|project||string||none||Limit to provided project identifiers.|
|description||string||none||More information about the specific resource.|
|tags||map[string]string||none||List of labels applied to the resource.|
|order||string||desc||Order to use when sorting the specified fields. Type: enum(asc,desc).|
|sort||string||none||Fields on which to sort. Note: Specify the fields that you want to use for sorting. When doing so, consider the operational overhead of sorting fields.|
|limit||int||30||Pagination: Number of items to return.|
|page||int||1||Pagination page number strategy: Specify the page number within the paginated collection related to the number of items in each page.|
|created||int64||none||Unix timestamp that shows when the resource was created (in milliseconds).|
|updated||int64||none||Unix timestamp that shows when the resource was last edited (in milliseconds).|
Harness uses conventional HTTP status codes to indicate the status of an API request. Generally, 2xx responses are reserved for success and 4xx status codes are reserved for failures. A 5xx response code indicates an error on the Harness server.
|415||Unsupported Media Type|

The current version of our Beta APIs is yet to be announced. The version number will use the date-header format and will be valid only for our Beta APIs.
All our beta APIs are versioned as a Generation, and this version is included in the path to every API resource. For example, v1 beta APIs begin with
app.harness.io/v1/, where v1 is the API Generation.
The version number represents the core API and does not change frequently. The version number changes only if there is a significant departure from the basic underpinnings of the existing API. For example, when Harness performs a system-wide refactoring of core concepts or resources.
We use pagination to place limits on the number of responses associated with list endpoints. Pagination is achieved by the use of limit query parameters. The limit defaults to 30. Its maximum value is 100.
Following are the pagination headers supported in the response bodies of paginated APIs:
X-Total-Elements : 30 X-Page-Number : 0 X-Page-Size : 10
