VPC REST API

[samueldion]

Hello all,

Just a general question here. Can the API be created and functional just as well using a REST API within a VPC. What would be the easiest way to go about it to make that edit in AWS? I have everything working with the HTTP API and want to make the switch.
Note that I am novice in anything cloud architecture 😊

Thank you,
Samuel

Hi @samueldion!

To frame the question, are we talking about sending images to S3 or telemetry to AWS IoT Core?

Hi Mattias,
Sending images to S3!

Images are sent from the Axis camera to the API Gateway. A REST API is just a set of REST resources on the API Gateway. I haven't tested, but I can't think of any issues with setting up the REST resources, given you pass the important parts of the request to the Lambda function (like the filename specified as a request header), and given that the API Gateway can be accessed from a camera in the VPC.

Hello @mattias-kindborg-at-work ,
What is the content body that is sent from the camera? I am trying to implement it in Postman and get it working as a REST API, but I am just getting an issue by not knowing how the Axis camera actually send the HTTPS POST request. I don't know if my question make sense? Anyway, just wondering how to get it to work in Postman :)

You can use the following properties in Postman to simulate an Axis camera sending an image:

• Method: POST
• Path: <url>
• Query parameters
  • accessToken: <access token>
• Headers
  • Content-Disposition: attachment; filename="<filename>"
• Body
  • Binary: Browse and select file

where <url> is the recipient, <access token> is the access token and filename is the name of the image you are in the process of sending. You can also follow along in the code to see what the receiving function expects from the request.

Thank you Mattias, I indeed followed the code and it worked well.
Cheers,

Hey Mattias,
I am coming back to this because I need to add a custom header to the Axis call so that it can reach the proper API in the VPC. I just don't know where to put it in the Axis settings. I am not seeing the option to do so in the Camera interface...
Thank you,
Samuel

Hi Samuel! Unfortunately you can't specify a custom header in the camera UI 😞
