Newbie - Retrieve and save an image file

Good Morning,

Am completely new to Power Automate so reaching out for assistance.

Am actually working in a Power BI Report, so using the Power Automate visual within Power BI.

My task is to retrieve an image file via an HTTP Post call to a Wasabi Cloud Server.

I've been told this returns an image file.  It is here I am stuck.  Hoping someone can provide some guidance as to what my next steps should be.

Much thanks in advance!

I am not too familiar with this, but if you are trying to retrieve something shouldn't you be using the GET method rather than POST?

@Jondoesflow,

Appreciate you taking the time.

I was not sure about this either, but this is what I was told to do by my Developer.

Additional info I received is that my next action is Response.  The Post method does return a JSON Response so have added that to my flow.

I was provided with a sample Response from Postman.  Next step is to try to figure out how to populate this Step.

Thanks again.

 

Click on generate from sample and put your response from postman in there. 

@Jondoesflow,

I believe I have successfully parsed my JSON Response.

Now, I am trying to figure what the next step in my flow should be.

Thinking along the lines of creating a Temp Table somewhere (Sharepoint, Dataverse, OneDrive ) and then adding the results as a record in this Temp Table.  Does this make sense to you or would you recommend another approach?

 

It depends what the end goal is

@Jondoesflow,

End goal is to display an image in my Power BI report.  So working backwards from that:

I need a 1 record table (thinking Excel file) that will be imported by Power BI.

The trigger to import will be when a new record is added.

I believe the new record in my table should b the contents of the JSON Response

"Done": {
"WasabiFile": {
"Id": "bd764a5f-f12c-4f34-aa2d-65cd428a5461",
"FileName": "Rear Door Inspection 1.png",
"Contents": "/9j/4AAQSkZJRgABAQEAYABgAAD/......

The Contents is the image in Base64 format and can be as long as 400,000 characters.  So as I write this, I just realized Excel will not be able to handle the "Contents" without splitting this text field.  Another hurdle I need to overcome.
