Parley Chat and Messaging API

Introduction

Parley's Chat and Messaging API enables you to offer your customers a messaging channel integrated into your website or app. This chat solution enables secure communication between your agent/bot desktop and client website/mobile app.

Devices displaying a webpage or app start communication to the company endpoint, where agents on desktop clients or a bot can respond to the customer's message. Messages can contain text or images.

Getting started

Make sure you've read Getting Started for more info on how to register your application and start trying out our APIs.

Authentication

The API follows the KPN Store API Authentication Standard to secure the API. It includes the use of OAuth 2.0 client_id and client_secret to receive an access token.

Go to the Authentication tab on top of this page to find out how to:

• Authenticate to an API using cURL.
• Authenticate to an API on Swaggerhub.
• Import Open API Specifications (OAS), also called Swagger files into Postman.

How to...

Subscribe a device

• You need to subscribe the device before you can send and get messages. When you do not subscribe, we can't tell who you are, so this is important.
• When you subscribe you will also want to setup the pushToken and pushType of your device to receive updates when a new event or message is available for this device.
• For each request, you need to provide the UniqueAppDeviceID key. This is a unique identifier that you have to create here for each device. The identifier has a minimum length of 10 characters.

SwaggerHub:

1. Select POST /devices.
2. Click Try it out.
3. Edit the parameters by filling out the unqiueAppDeviceId. For receiving messages also fill out the pushToken, pushType and type parameters. Please refer to the Swagger file for more detail.
4. Click Execute.
5. Check the response code and message.

Postman:

1. Select (GET) Config.
2. Fill out uniqueAppDeviceId in the Headers section.
3. Click Send.
4. Check the response code and message.
