How to pass attachment (file) from Copilot Studio to Power Automate?

Hi everyone,

We have created a chatbot for our customers and it creates a case in Dynamics when the question cannot be answered. After collecting the case data, it asks for a file to upload. We can save the file in Copilot Studio as a variable “file”.

The chatbot calls a Power Automate flow and gives all variables as information to create a case. Only for the type “file” the information cannot be passed. I get the error message that “file” is not supported.

I am thinking about passing the file as JSON and parsing it in Power Automate Flow to get the file. Has anyone solved a specific use case and can help me with the definitions?

I am having trouble in Cipilot Studio getting the file as JSON and passing it to Power Automate as a string.

Hi,

To pass an attachment (file) from Copilot Studio to Power Automate, follow these steps:

Step 1: Enable File Upload in Copilot Studio

In Copilot Studio, go to the topic where you want to handle file uploads.

Add a User Input node.

Choose File Upload as the input type.

This will allow users to upload files in the conversation.

Step 2: Create a Power Automate Flow

Open Power Automate and create a new Instant Cloud Flow.

Select Copilot Studio as the trigger and choose "When an action is called".

Add an input parameter of type File.

Add actions to process the file, such as:

Save to SharePoint, OneDrive, or Dataverse.

Send via email.

Convert and manipulate the file

Step 3: Connect Copilot Studio to Power Automate

In Copilot Studio, go to the node where you want to call Power Automate.

Click "Call an action" and select Power Automate.

Choose the flow you created.

Map the file upload input to the Power Automate file parameter.

Step 4: Handle File in Power Automate

The file will be received in Power Automate as base64 content.

Convert and use it as needed (e.g., store in SharePoint or Dataverse).

I hope it will help you to resolve your issue.

Thanks for your answer. I cannot implement the 2nd step. I cannot find the exsact trigger to add inputs. I used "When Copilot Studio calls a flow", but I cannot add file type there.
