BILL API Reference Overview

Use the BILL API to integrate your application with BILL Accounts Receivable (AR) and Accounts Payable (AP) automation capabilities.

The API Reference section enables you to view sample code in your choice of language and also test sandbox API calls in the documentation.

Prerequisites

Sign up to create your API sandbox developer account. Retrieve your userName, password, orgId, and devKey.

Test with the /Login.json cURL command

Sign in to your BILL sandbox developer account with the /Login.json API endpoint. The required fields for signing in are userName, password, orgId, and devKey.

Set the required values in the cURL command example and run the command in the Mac Terminal, Windows Command Prompt, or your choice of command line interface.

curl --request POST \
--url 'https://api-sandbox.bill.com/api/v2/Login.json' \
--header 'content-type: application/x-www-form-urlencoded' \
--data 'userName={username}' \
--data 'password={password}' \
--data 'orgId={organization_id}' \
--data 'devKey={developer_key}'

In the response, your API session is created and a sessionId is generated. Save this sessionId value. All subsequent API requests require a sessionId and devKey for confirming that you are in a signed in session.

Test with /Login.json on this website

You can fill in required fields, test sandbox API calls, and retrieve server responses on this website.

1. Select Login > Login.
2. In the FORM DATA section, enter userName, password, devKey, and orgId. You retrieve these values as part of your API sandbox sign up process. See BILL sign up process for more information.
3. Click Try It!. In the response, a sessionId is generated.

Save this sessionId value. All subsequent API requests require a sessionId and devKey for confirming that you are in a signed in session.
