Vayu API Client Library

Overview

The Vayu API client library in TypeScript allows you to submit events for processing and storage, manage billing-related entities, and perform various other operations seamlessly.

Installation

Install the Vayu API client library using npm:

npm i vayu-ts

Usage

Initialization

Initialize the Vayu API client. The baseUrl parameter is optional and defaults to Vayu's public API servers.

import { Vayu } from 'vayu-ts';

const vayu = new Vayu(
  'your-access-token',
);

Authentication

Login and authenticate

await vayu.login();

Events

Sending Events

To send a batch of events for processing and storage:

const events: Event[] = [
  {
    name: 'api_call',  // The distinctive label assigned to an event
    timestamp: new Date().toISOString(),  // The exact moment of event occurrence in ISO 8601 format
    customerAlias: 'customer_12345',  // A unique identifier assigned to each customer
    ref: '4f6cf35x-2c4y-483z-a0a9-158621f77a21',  // A universally unique identifier for each event
    data: {
      key1: 'processing_duration',  // Example additional data
      key2: 'api_url'  // Example additional data
    }
  }
];

const response = await vayu.events.send(events);

console.log(response.validEvents);
console.log(response.invalidEvents);

Querying Events

To fetch events occurring within a specified timestamp range:

const response = await vayu.events.query({
  startTime: '2023-09-01T00:00:00.000Z',
  endTime: '2023-09-30T23:59:59.999Z',
  eventName: 'api_call',
  limit: 10
});

console.log(response.events);

Getting Event by Ref ID

To get a specific event using its reference ID:

const response = await vayu.events.get('4f6cf35x-2c4y-483z-a0a9-158621f77a21');

console.log(response.event);

Deleting Event by Ref ID

To delete a specific event using its reference ID:

const response = await vayu.events.delete('4f6cf35x-2c4y-483z-a0a9-158621f77a21');

console.log(response.event);

Customers

Creating a Customer

To create a new customer:

const response = await vayu.customers.create({
  name: 'John Doe',
  externalId: 'customer_12345'
});

console.log(response.customer);

Updating a Customer

To update an existing customer by ID:

const response = await vayu.customers.update('customer-id', {
  name: 'Jane Doe',
  externalId: 'customer_67890'
});

console.log(response.customer);

Deleting a Customer

To delete a customer by ID:

const response = await vayu.customers.delete('customer-id');

console.log(response.customer);

Contracts

Assigning a contract to a customer

In order to assign a contract to a customer you would need to provide the customer Id and the relevant plan

	const response = await vayu.contracts.create({
    startDate: new Date(),
    endDate: undefined,
    customerId: '1f4cf23x-2c4y-483z-1111-158621f77a21',
    planId: '4f6cf35x-1234-483z-a0a9-158621f77a21',
  })

  console.log(response.contract)

Meters

Meters are entities that track and aggregate usage data based on events. They are crucial for billing and monitoring purposes.

Listing Meters

To get a list of meters:

const response = await vayu.meters.list({
  limit: 10,
  cursor: 'next-cursor'
});

console.log(response.meters);
console.log(response.total);
console.log(response.hasMore);
console.log(response.nextCursor);
