Read Json Object from HTTPEndpoint Incoming request from another API

[glime-ai]

To read JSON sent from another API to an Elsa Workflow V2 Dashboard HTTP Endpoint, you would typically use the HttpEndpoint activity to set up an endpoint that can receive HTTP requests. The JSON payload sent to this endpoint can then be accessed within the workflow.

Here's a basic example of how you might define a workflow that reads JSON from an incoming HTTP POST request:

1. Add an HttpEndpoint activity to your workflow with the following settings:

   • Method: POST
   • Path: /your-endpoint-path (e.g., /api/data)

2. Add a RunJavaScript or similar activity to process the incoming JSON. You can access the JSON payload using the input variable, which represents the incoming request content.

3. Use expressions to access the JSON properties. For example, if the JSON payload is {"name": "Elsa", "age": 3}, you can access the name property with an expression like input.name.

Here's a sample JSON representation of such a workflow:

{
  "name": "ReceiveJsonWorkflow",
  "activities": [
    {
      "id": "http-endpoint",
      "type": "HttpEndpoint",
      "properties": {
        "Method": "POST",
        "Path": "/api/data"
      }
    },
    {
      "id": "process-json",
      "type": "RunJavaScript",
      "properties": {
        "Script": "return { name: input.name, age: input.age };"
      }
    }
  ],
  "connections": [
    {
      "sourceId": "http-endpoint",
      "targetId": "process-json"
    }
  ]
}

To execute this workflow, you would send a POST request to https://localhost:5001/workflows/api/data with a JSON payload.

Here's a sample curl command to send a JSON payload to the workflow endpoint:

curl --location --request POST 'https://localhost:5001/workflows/api/data' \
--header 'Content-Type: application/json' \
--data-raw '{
    "name": "Elsa",
    "age": 3
}'

Please note that the actual endpoint URL and port may vary based on your Elsa Dashboard setup.

For more detailed examples and documentation, you can refer to the Elsa Workflow documentation and samples provided in the context section, specifically the HTTP Backend API and HTTP Post Users API samples.

Is "type": "RunJavaScript", available in Version 2.13 Dashboard. If not which activity should I use.

[Rathna314]

Can someone respond please. Is "type": "RunJavaScript", available in Version 2.13 Dashboard. If not which activity should I use. I am unable to see RunJavaScript in 2.13 version.

Yes, but it's not added to the system by default. To make it available, you need to call AddJavaScriptActivities on the elsa options builder.

This guide covers a similar scenario where it demonstrates reading a payload sent to an HTPT Endpoint activity.
