I do not have any background on Web services or Powershell.
Due to restrictions of our ETL tool not handling multipart/form-data, I need to call the REST API (Post) from PowerShell. I am using the Invoke-RestMethod cmdlet.
API is a post method doing a bulk import on the target application. It has a header for Authorization with an access token. I have figured out the headers IDictionary object.
The call has a multipart/form-data request body.
In postman, I do the following:
For key type I choose file. In key field I put "file" and in value field I place the filename with the path.
How do I replicate this request body in PowerShell?
All links I searched so far seem to be similar to my requirement but I am not able to gather/understand enough to implement.
Your help is appreciated.

I'm working on a pretty straight forward proof of concept to log-in via a POST action using Talend.
From the application side, I use a POST with a body to then receive a cookie. However, I'm at a loss for how to get the cookie details from the response of the endpoint.
In my forum lurking, there appear to be two approaches: one using tREST, the other using tRESTClient.
Using tREST, I can successfully post to the endpoint, but I can not appear to retrieve the response header or body:
This is the tREST component properties:
The cookie passed from this call needs to be recycled into subsequent calls in order for them to authenticate.
I'm hoping to understand how to get the Cookie out and passed along, either with tREST or tRESTClient. My issue with tRESTClient is that I do not have a way to pass the body to that component.
Any thoughts?
On your last point - you can pass the body to tRestClient by having a flow going into tRestClient. That flow can have a "string" field containing the body in json format, and that field will need to map to the "string" column in the component input schema.
If, in your case, you do not already have a flow containing the body, you can generate it by using the tFixedFlowInput component.
I am placing a web task call to an api.
The body is simple
["val-01-001"]
(note, this works with either single or double qoutes)
If i use this exact value for the body in postman, it works.
If i use this exact value in the body of the web call, the web call tells me "The posted data is not valid. Perhaps it is not well-formed or match with the samples.Please verify."
I dont have access to the api code or backend so i cant see exactly what its receiving.
Any idea what Data factory might be doing to the body causing it to be rejected?
I added a Content-Type header with a value of application/json, but this didnt help.
Below are the input and out from the web call and the same call in postman, which works:
Web Call input
Web call output
Exact same call in postman
I am trying to call REST API related to Azure Search through postman.
Here is the API link: (Check Step 1: Create a data source)
https://learn.microsoft.com/en-us/azure/search/search-howto-indexing-azure-blob-storage
Have sent parameter api-key: [admin key] in form-data and other through jSON object.
I am getting 403 error.
Whats the correct way to get required output?
Update :
Changed position of api-key. Still getting the error as :
Is there any additional setting for postman to work with Azure's REST APIs?
Please make sure that you pass api-key in Headers instead of form-data and also all the headers should be selected. Once you do that, things should work just fine.
I am trying to get the form data from a multipart/form-data POST to my ASW Lambda web service via API Gateway.
The HTTP POST has Content-Type "multipart/form-data" and body that is URL encoded. File data is also sent in this post (hence the multipart, I guess).
The web service needs to integrate with a thirdparty service, so changing the format of the POST isn't really an option.
I have seen this thread talking about converting the URL encoded data to JSON object for use in Lambda, but this doesn't do the trick.
I have also tried setting the Integration Request -> Mapping Templates for content type multipart/form-data to Input passthrough. This didn't help either.
I did come across another question about uploading a file using multipart/form-data, but since I'm not interested in the file, just the body, that answer didn't help.
Below find screenshot (sorry) of the captured post via runscope.
If the goal is to use Lambda, you'll need to pass valid JSON to the function. Currently there isn't a way to JSON-ify data inside Api Gateway that comes in as non-JSON data.
Our short term fix (on our backlog) is to provide a variable in the mapping templates to grab the raw input of the request. That way you could do a simple JSON conversion using a template like:
{
"body" : "$input.body"
}
or something like that.
Check out the mapping template reference for more info: http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html
Edit 4/7 - feature has been released as $input.body
Does anyone know how to create a proxy service that will handle this sort of thing?
What I'm looking for is a path parameter and a post body being formatted similar to this:
POST www.myurl.com/{123}
Post body:
myId=1&myOtherId=2
I am currently passing in an XML document and I'm doing an insert on the http:relative-URI element in the transport. This seems to work.
I am also currently doing an insert on the http:query-parameters for my post body name/value pairs.
I am inserting these on the outbound variable. When I debug, both are showing up and I'm contacting the REST service. I am getting a 400 -- Bad Request error. This happens when the post body is not configured correctly.
Any ideas how to do this?
If you are just Posting an XML, then while creating Proxy Service, Select Service Type as Any XML.
