List Previous Events

In this code snippet you learn how to list the previous page of Events.

Example

Ensure the following variables are set to your required values using any convenient method:

Key Description
CONVERSATION_ID The unique ID of the Conversation.

Prerequisites

You will need to use an existing Application that contains a Conversation in order to be able to create Events and then list them. See the Create Conversation code snippet for information on how to create an Application and some sample Conversations.

npm install nexmo@beta

Create a file named list-prev-events.js and add the following code:

Copy to Clipboard
const Vonage = require('@vonage/server-sdk')

const vonage = new Vonage({
  apiKey: VONAGE_API_KEY,
  apiSecret: VONAGE_API_SECRET,
  applicationId: VONAGE_APPLICATION_ID,
  privateKey: VONAGE_APPLICATION_PRIVATE_KEY_PATH
})

  (error, result) => {
    if (error) {
      console.error(error);
    } else {
      vonage.conversations.events.next(result, (error, result) => {
        if (error) {
          console.error(error);
        } else {
          vonage.conversations.events.prev(result, (error, result) => {
            if (error) {
              console.error(error);
            } else {
              console.log(result);
            }
          })
