## Overview

REST API integration enables an Edge System to connect with RESTful API.

## Supported Communication

- Outbound (Publish data from Edge to REST Server ) - Yes
- Inbound (Subscribe data from REST Server to Edge) - No

## Configurations

| **Variable**           | **Detail**                                                                                                                                                                                            | **Required** |
| ---------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------ |
| Name                   | Enter a name for the connector                                                                                                                                                                        | Yes          |
| Method                 | HTTP methods in REST APIs: GET, POST, PUT, and DELETE                                                                                                                                                 | Yes          |
| Endpoint               | Endpoints are the entry points to interact with the API                                                                                                                                               | Yes          |
| Headers                | A request header is an HTTP header that can be used in an HTTP request to provide information about the request context                                                                               | Yes          |
| Params                 | URL parameters (query strings) additional information for a given URL                                                                                                                                 | No           |
| Mapping                | Data from a payload could be mapped into a custom one. Example: \{"from": "to"} where "from" is a key from predefined payload, and "to" is a key from destination payload.                            | No           |
| Parallel publish count | Parallel publish count indicates how many data streams or data items are being sent from the edge system to a central system or cloud simultaneously.                                                 | Yes          |
| Insecure skip verify   | InsecureSkipVerify controls whether a client verifies the server's certificate chain and host name. Select to disable verification                                                                    | No           |
| Throttling limit       | Set a limit on the number of outbound messages per second. If sending data to a server that has restrictions on the rate of incoming messages, this ensures that no messages are lost.                | No           |
| Persistent storage     | If enabled, messages in the outbound queue are stored on disk. If there are interruptions in connection or power loss, messages will be retained and eventually sent when the connection is restored. | No           |
| Queue mode             | Select the sequence of data transfer: FIFO or LIFO. Selecting FIFO (First In First Out) will send the earliest message first. Selecting LIFO (Last In First Out) will send the latest message first.  | No           |
