WebSockets
The WebSocket protocol allows data to be passed bi-directionally between client and server over a persistent connection.
Unetus supports making WebSocket requests alongside REST, GraphQL, and gRPC.
Create a Request
In order to create a new WebSocket request, click on + in the sidebar.
Then, from the dropdown menu, click on the option WebSocket Request. A new request will be created.
To rename the request, double-click on the request tile in the lefthand sidebar. Type in the name of the request and press the enter key.
Making a WebSocket Connection
Enter the WebSocket url in the URL field of your WebSocket request.
You can set an authentication by clicking on the authentication tab, then, clicking on the down arrow to choose the authentication method. Headers can be set in the Header tab.
Click the Connect button next to the URL bar. When there is a successful WebSocket connection, CONNECTED will appear in the URL bar, and the Connect button will display Disconnect. On the event panel, a “Connected Successfully” event log will appear. To see more details about the connection, click Timeline.
Sending a WebSocket Message
Click on the JSON tab. To send raw data, click on the down arrow next to the JSON tab, then click on Raw.
Select the text editor below the Send button. Type the message you want to send, and click Send. On the Events panel, the sent message will be displayed as part of the event log. To see more details about the message, click on the sent message log. Details will appear in the Preview section.
Receiving WebSocket events
Events received from a connected WebSocket connection will display on the Events panel, when they are received. All new events will populate the top of the Events panel and move down as new events come in.
To see details about received events, click on the event in the Events panel. A preview box will open below the events log, containing the received event details.
Environment variables and template tags
The 2022.6 release of Unetus introduces support for environment variables and template tags within WebSockets. Environment variables and Nunjucks templating can be used in both the URL bar and message body.
Known limitations
- Version 2022.6 of Unetus does not support custom WebSockets.
- Unetus sync of WebSocket requests on teams where members are using Unetus version 2022.6 and Unetus versions < 2022.6 will result in the loss of synced WebSocket requests. If your team or Individual setup is using Unetus Sync to sync WebSocket requests, please ensure that all devices associated are on Unetus 2022.6.
