Not able to convert x-www-form-urlencoded (Postman) to WebApi

Rufus — Thu, 03 Dec 2020 12:24:00 GMT

Hi, anyone who knows how to "convert" my Postman POST command to BP Web api format?

In Postman, the keys are in Body as x-www-form-urlencoded.

Converted to CURL (it looks like this):

curl --location --request POST 'https://xxxx' \

--header 'Content-Type: application/x-www-form-urlencoded' \

--data-urlencode 'grant_type=xxx' \

--data-urlencode 'scope=xxx' \

--data-urlencode 'username=xxx' \

In BP Web api \ Request\ Body content \ Template, I have tried both format 'key1=[value1]'&'key2=[value2]' and JSON format like { "key1": "[value1]", "key2": "[value2]"} (Content-Type= application/x-www-form-urlencoded and application/json).

Both elternatives return HTTP 400 error (which is syntax error, I quess).

Hi Ruben,

You can add the parameters in the URL path like https://xxxx/?key1=[value1]&key2=[value2] with Body Content set to None.

I have the same question as Ruben. I tried the solution that Shashank recommended, but that did not work either. I get a 404 Not Found message returned: "No resources match requested URI"

You can create a body template and place the parameters in the body in a similar format to how you'd define them as query parameters. This is how your making an HTTP POST. Here's a body template example:

grant_type=[Grant Type]&client_id=[Consumer Key]&client_secret=[Consumer Secret]&username=[Username]&password=[Password]

Hi Ruben,

As well as what Eric has mentioned you should also make sure that the header is set in either each action or in the API service such as below.If this doesn't work then you should look to select the "Enable Request Data Output Parameter" tick box under the action so you can see what you are sending and match it to the postman output.

Hope this helps

Hi,

I am facing an interesting issue with a POST to get the access token to interact with Sharepoint list. The call is currently working in Postman but not in BP webservices.

The error I am getting is as follows:
--------------------------------------------------
HTTP Status Code: 400
HTTP Response Content: {"error":"invalid_request","error_description":"AADSTS900144: The request body must contain the following parameter: 'grant_type'.......
-------------------------------------------------

The URL I am using is = https://accounts.accesscontrol.windows.net/[TID]/tokens/OAuth/2

Body (Template):
{
"grant_type": "client_credentials",
"client_id": "[XXXXX]",
"client_secret": "[XXXXX]",
"resource": "00000003-0000-0ff1-ce00-000000000000/[XXXXX.com]@[XXXXX]"
}

Header:

Every time I run this it fails with the error above but it works perfectly in postman. Are you in a good position to support me with this?

Hi Kapeteni,

The body template should be in this format

grant_type=[client_credentials]&client_id=[XXXXX]&client_secret=[XXXXX]&resource=00000003-0000-0ff1-ce00-000000000000/[XXXXX.com]@[XXXXX]

Hi Kapeteni,

www form urlencoded uses a slightly different language which Postman converts between however BluePrism does not.

What you will need to do it to convert your body from JSON into this new format as Shashank has detailed. Postman allows you to select between JSON and raw text but BluePrism will automatically convert this so you just need to put the text with appropriate values but without quotation marks

Hi Ronan,

I have a similar problem but I cannot solve it with what you have proposed, I have my request in postman and it works as expected:

I am receiving "Internal : Unexpected error Error during Web API HTTP Request
HTTP Status Code: 400
HTTP Response Content: Bad Request"

I am not sure if my problem is related with the Authorization or with the Body itself. Do you know what could be wrong? It would be very helpful if you could give me a hand,

Thank you in advance.

@Jesus Jordan,

By entering a value for Common Authentication you're telling Blue Prism to handle the authentication when in fact you want to handle it yourself. Change the Common Authentication to None and then pass in the username and password as input parameters on your Get Token action. Then you can reference them in the request body.

Hi Shashank,

I tried the body format which you suggested but still I am getting the error,
{ "error": "Invalid request" }

Below is my API body format,
grant_type=[refresh_token]&refresh_token=[XXXXX]

whereas I tried it from POSTMAN, API working successfully with x-www-form-urlencoded content type, with below format,

grant_type:refresh_token
refresh_token:XXXXX

shashank.kumar280 — Fri, 14 Jul 2023 11:29:00 GMT

Trupti,

What do you intend to pass in grant_type?

Value of Data Item refresh_token

or string "refresh_token"

@Trupti

Please try as per suggestion from Jishnu. If it still doesn't work then I would suggest posting screenshot of your POSTMAN configuration here.
