About the Sauce REST APIs

Sauce Labs exposes a set of REST API endpoints that allow you to perform operations, manage accounts, and retrieve data programmatically so you can use the Sauce platform in the way that best suits your business logic.


You can check the current accessibility of any Sauce Labs system on the Sauce Labs Systems Status page.

What You'll Need

Accessing the APIs

The Sauce Labs APIs are organized around REST. Each endpoint is structured as a resource-oriented URL that accepts inline query parameters and form-encoded request bodies, then returns JSON-encoded responses.

Each endpoint is constructed from a {base-url} prefix that is based on the data center associated with the Sauce Labs account for which the request is relevant, plus the latest version for the given method. The following table provide the base URLs for each data center.

US East



The request examples throughout the API documentation utilize variables in place of Sauce Labs authentication credentials. Consider setting your credentials as environment variables so that you can simply copy, paste, and run the code examples rather than manually passing your credentials for each call.

The Sauce Labs API uses API keys to authenticate requests. You can view and manage your API key under your Sauce Labs User Settings.

Authentication to the API is performed via HTTP Basic Auth. Provide your username and API key as the basic auth username and password values, respectively. All requests must be made over HTTPS. Calls made over HTTP or without proper authentication will fail.

You can provide your authentication credentials as inline parameters of your request or using a Basic Header.

Inline Authenticated Request Example
curl -u "$SAUCE_USERNAME:$SAUCE_ACCESS_KEY" --location \
--request GET ''
Header Authenticated Request Example
curl -L -X GET '' \


The API is versioned by URL, each of which may be in a different stage of release. The currently published version of each endpoint is reflected in the URL itself, as demonstrated in the following two endpoints:



Unspecified method requests default to GET. All other supported request types (PUT; POST; DELETE: PATCH) require setting the Content-Type header to application/json.

Status Codes

Sauce Labs uses conventional HTTP response codes to indicate the success or failure of an API request. In general, codes in the 2xx range indicate success, while codes in the 4xx range indicate an error that caused the request to be denied. Codes in the 5xx range indicate an error reaching the Sauce Labs server (which is rare). The following table provides a summary of response codes returned by the APIs.

200 - OKThe request was processed successfully.
201 - CreatedThe request has been fulfilled, resulting in the creation of a new resource. Typically returned for POST, PUT, or PATCH requests that pass data values for the purpose of creating or updating records.
400 - Bad RequestThe request was not acceptable, often due to missing or improperly formatted parameters. This code may be accompanied by additional information in the form of a body payload or a message attribute of the response code.
401 - UnauthorizedThe authentication credentials were missing or not valid.
403 - ForbiddenThe authenticated user does not have permission to perform the request.
404 - Not FoundThe requested resource does not exist. This can refer to the endpoint itself (check for typos in the request URL), or the requested data (the job ID does not match any existing records, for example). This code may be accompanied by additional information in the form of a body payload or message attribute of the response code.
429 - Too many requestsThe number of requests has exceeded the rate limit for the API.
500 - Internal Server ErrorThe Sauce Labs server was not responsive.

Following are some sample error responses that include additional detail.

404 Typo in Request URL Error Response
<!doctype html>
<html lang="en">

<title>Not Found</title>

<h1>Not Found</h1>
<p>The requested resource was not found on this server.</p>

404 User ID Not Found Error Response
"detail": "Not found."
400 Missing Required Parameter Error Response
"verify_password": ["This field is required."]

Rate Limits

The Sauce Labs REST API places rate limits on some endpoints in order to prevent over-utilization.

For example:

  • Incoming authenticated API requests have rate limits imposed against the individual user accounts.
  • Incoming unauthenticated API requests have rate limits imposed against the IP addresses.

Requests received after the rate limit is reached return a 429 response code indicating that the number of allowable requests has been exceeded.

Rate Limit Breakdown

REST API EndpointRate LimitAuthenticated
All authenticated request endpoints10 requests per second, or 3,500 requests per hour✔️
All unauthenticated request endpoints2 requests per minute

JSON Response Formatting

The request examples throughout the API documentation are appended with | json_pp as a convenience to return the response in a more readable format that does not require the installation of any additional tools.

You can remove the | json_pp reference from your requests to have responses returned as raw JSON, or you can specify a different syntax formatter of your choosing, such as JQ.
