How to send a POST API request in UiPath (step-by-step)

Hi UiPath Community :waving_hand:,

I’m new to working with APIs in UiPath and need some guidance on how to send a POST API request and read the response properly.

I have an API endpoint (URL), a request body (JSON), and I want to send it from UiPath using the HTTP Request activity. I’m a bit confused about where to set the URL, headers, and JSON body, and how to capture the response.

URL : http://192.168.28.11/hmsspeciality19scripts/ASBTStructRest.dll/datasnap/rest/TASBTStruct/savedata

Request Body :
{
“_parameters”: [
{
“savedata”: {
“axpapp”: “hms11hr”,
“s”: “”,
“username”: “webuser”,
“password”: “827ccb0eea8a706c4c34a16891f84e7b”,
“changedrows”: {},
“transid”: “eincd”,
“recordid”: “0”,
“recdata”: [
{
“axp_recid1”: [
{
“rowno”: “001”,
“text”: “0”,
“columns”: {
“emp_no”: “109676”
}
}
]
}
],
“afiles”: “”,
“attachmode”: “”,
“params”:
}
}
]
}

Response :

{“result”:[{“message”:[{“msg”:“Insurance Card Saved”,“recordid”:“1438880003792”}]}]}

URL goes in endpoint url property.
Headers goes in header collection.
JSON body goes in body.
For response, there is an output parameter, define a variable for that and use it to capture response.

Pls, Need UiPath activity based code

Step 1: Install and Import Dependencies
Step 2: Add HTTP Request Activity

  • HTTP Request → Method: POST
  • URL
  • Headers (Content-Type: application/json)
  • Body (JSON)
  • Output → responseText
  • Deserialize JSON → Input: responseText → Output: jsonResponse
  • Log Message → Message:
"Message: " + jsonResponse("result")(0)("message")(0)("msg").ToString

Message: …
Record ID: …

@srijo2703

Is the response coming in json?

First try to print the response body to check the value

Cheers
