Implementing Autodesk APS in Microsoft Power Automate Custom Connector

I'm working on creating my own custom connector in a MS flow to call Autodesk's [Data Management API], and can't get the step 5 in their documentation: direct upload to a signed S3 URL to work in my flow.

I tested the rest of the process in postman and it's working there. I also tested running step 5 using curl command in a .sh script (just like their example) and can confirm that the signed URL is properly generated, and I can finish the upload just fine.

There are two ways I've tried executing the upload in PowerAutomate;

  1. using a HTTP action that takes the signed URL, "PUT" as a method, with my file content in the body. Here's the code view of this action:

    {
  "type": "Http",
  "inputs": {
    "uri": "[REDACTED SIGNED URL]",
    "method": "PUT",
    "body": "@body('Get_file_content')"
  },
  "runAfter": {
    "Upload_file_to_S3_signed_URL": [
      "Succeeded"
    ]
  },
  "runtimeConfiguration": {
    "contentTransfer": {
      "transferMode": "Chunked"
    }
  }
}

    The error I get in this case is as follow (no actual output, just the error):

    InvalidProtocolResponse

    The response to partial content upload initiating request is not valid. The response to initiating partial content upload request must contain a valid location header.

  2. I built a dedicated custom connector (because the host name for S3 upload is different from the other Autodesk APIs), here's the swagger json:

    swagger: '2.0'
info:
  title: APS S3 Signed URL Uploader
  description: Direct upload to S3 signed URL generated by the Data Management API.
  version: '1.0'
host: com-autodesk-oss-direct-upload.s3-accelerate.amazonaws.com
basePath: /
schemes:
  - https
consumes:
  - application/octet-stream
produces:
  - application/json
paths:
  /upload:
    put:
      summary: Upload file to S3 signed URL
      operationId: UploadToURL
      parameters:
        - name: signedURL
          in: query
          required: true
          type: string
          description: Signed URL generated by the Data Management API.
        - name: fileContent
          in: body
          required: true
          schema:
            type: string
            format: binary
            description: Binary file content to upload.
      responses:
        '200':
          description: Upload successful
          schema:
            type: object
            properties:
              message:
                type: string
                example: File uploaded successfully.
        '400':
          description: Bad Request
        '500':
          description: Internal Server Error
securityDefinitions: {}

    Running it this way, I get a 403 error with the following output body:

    <?xml version="1.0" encoding="UTF-8"?>
<Error><Code>AccessDenied</Code><Message>Access Denied</Message><RequestId>V48YVK8JA62E8GX3</RequestId><HostId>z6CEun8FVfqQEB1ostuWqeWJUeEMtd9L0c4X5NsS70akh7sMSL6S3uC/I53IikjDD6waL5MjM/0=</HostId></Error>

I am not a developer by trade, so please bear with me if I completely missed something obvious! Any direction is much appreciated.

Solution

  • If you want to keep things simple you could use this endpoint instead:
    https://aps.autodesk.com/en/docs/data/v2/reference/http/buckets-:bucketKey-objects-:objectKey-signed-POST/
    You could create a custom connector just for this endpoint and then use HTTP component to upload to the URL it provides

    The direct S3 upload APIs are good if you want to upload big files and you want to upload the chunks in parallel, or if you can use our SDKs (which are using those endpoints to upload files)
