Eway Bill API Invocation

When you invoke Eway Bill API you need to take care of populating the headers correctly, creating the request payload, encrypting the payload and wrapping it in an envelope and then processing the responses (which usually require further decryption activities).

We are demonstrating 3 sample call logs (1 authentication, 1 for a post and 1 for a get) for your review to understand what the request / response payloads will look like

But before that, you will be required to encrypt some files during authentication with the NIC public key. Please note below the correct public key to use.

• Sandbox Public Key File for EWB
• Production Public Key File for EWB

Let us start with a sample call to authentication.

• Sample Authentication Call
• Sample Get Call
• Sample Generate Call
