Scenario 1: Customers with access to Avalara

If your organization already uses other Avalara products (like AvaTax or CertCapture) and has access to the signed in area of Avalara.com website, follow these steps to authenticate with the Avalara 1099 & W-9 API:

Note

If you already possess a license key for integration with other Avalara products, you can continue to use that same key. Generating a new license key through this process will automatically reset any previously created key.

Step 1: Sign In and Generate License Key

Sign in to the Avalara.com.
Go to Settings > License and API Keys.
Select Generate New Key.
Note your Account ID from the Account menu.

Step 2: Request a Bearer Token

Make aPOST request to Avalara’s identity service using theclient_credentials grant type:

curl -X POST 'https://identity.avalara.com/connect/token' \
   --header 'Content-Type: application/x-www-form-urlencoded' \
   --data-urlencode 'grant_type=client_credentials' \
   --data-urlencode 'client_id={{accountId}}' \
   --data-urlencode 'client_secret={{licenseKey}}' \
   --data-urlencode 'scope=avatax_api'

This command sends a POST request to the Avalara Identity service, specifying the necessary headers and data to authenticate and retrieve an access token. Make sure to replace{{accountId}} and{{licenseKey}} with your actual credentials.

Use the resulting bearer token to authenticate your API requests to the Avalara 1099 APIs.
