Onboarding Process
Step 1: Create a Test Account
It is highly recommended to start with a test account. Please use the Test Server to sign up and log in with your new credentials (Please note TIN used during signup will be your username). This allows you to test the entire process without affecting live data.
Step 2: Get Your Credentials
Once logged into the portal, from right top menu (click the TIN number for menu), follow the Update Merchant Address as well as Update FIRS Specific Info links. Provide and save the missing information at these links otherwise e-invoice generation will fail. Then in the same menu open Allowed Modes/Model Types link to get your Client ID and Access Key. These credentials are required to authenticate your API requests.
Step 3: Integrate with Our API
Consult the API documentation to understand how to structure your API calls. You will need to send your invoice data along with the Client ID and Access key to sign your invoices and make them FIRS e-invoices compliant.
Step 4: Handle API Responses
On a successful API call, the response will return an IRN (Invoice Reference Number) and a QR code, which you must print on your invoices. In case of failure, the response will provide an error code and message. Use this information to fix the issue and re-try the signing process.
Step 5: Go Live
Once you have a working process on the test server, you can onboard to the Live Server using the exact same process. All your signed invoices will be available on the SmartTax portal where you created your account.
