E-Way Bill API
Generate an e-way bill for any consignment in a single API call.
What the E-Way Bill API does
Generate e-way bills programmatically instead of keying them into the government portal. Send the consignment details and receive the EWB number and validity back. Calls carry your own GST portal API credentials (GSTIN, username and password), so filings are made as you, on your own registration. We never file on our own account.
Popular use cases
- →ERP and billing software issuing e-way bills at invoice time
- →Logistics and transport platforms moving goods across states
- →Warehouse and dispatch systems automating outbound consignments

}Frequently asked questions
Do I need my own GST portal credentials?
Yes. E-way bills are filed against your registration, so you create an API user on the e-way bill portal and pass those credentials with each call. It is your filing, not ours.
What does it cost?
A flat ₹3 per successful call. Failed calls are never charged — the wallet hold is released automatically.
Can I cancel or update a bill afterwards?
Yes. Cancellation, Part-B vehicle updates, validity extension and transporter changes are all separate endpoints on the same key.
