Power Apps – ChatGPT Integration

Posted on 10/23/2023by Angelo

In this article, let’s see how we can integrate ChatGPT with our Canvas App to add AI functionality.

ChatGPT is an artificial intelligence-based chatbot developed by OpenAI, specialized in conversing with human users. The acronym GPT stands for Generative Pre-trained Transformer, which means “pre-trained generative transformer.” With ChatGPT we can, for example, generate content, answer questions, Translate, summarize, complete sentences etc.

Feel free to write me if you need help.

Requirements

Basically, the Idea is call ChatGPT Service via Power Automate, get response and pass it to our App. Before start, you need ensure to have:

Premium Licence (Or Trial) to make Http Post request from Power Automate
An account with some cretit on OpenAI
Valid OpenAI API key

Build flow

In this Example, we’re going to call our flow from a Canvas App, passing a prompt and get an output. Trigger is Standard Power Apps connector:

Then, we must do an HTTP Post request to call OpenAI Service. According to Open AI documentation (at this this link) we need to specify in the following headers to make request:

URL: https://api.openai.com/v1/chat/completions
Content-Type: application/json
Authorization: Bearer $OPENAI_API_KEY

And as Body, a Json with:

Model
Messages
Temperature

Example:

{
     "model": "gpt-3.5-turbo",
     "messages": [{"role": "user", "content": "Say this is a test!"}],
     "temperature": 0.7
   }

In my case I parameterized the prompt, but of course you could also parameterize model or temperature, So, the action to call ChatGPT from flow is:

Now, we must get body response, parse it, extract result and pass information back to our app.

Add “Parse Json” action and use this schema (I suggest you do to first call to service and get response and then use “Generate from sample” option):

{
    "type": "object",
    "properties": {
        "id": {
            "type": "string"
        },
        "object": {
            "type": "string"
        },
        "created": {
            "type": "integer"
        },
        "model": {
            "type": "string"
        },
        "choices": {
            "type": "array",
            "items": {
                "type": "object",
                "properties": {
                    "index": {
                        "type": "integer"
                    },
                    "message": {
                        "type": "object",
                        "properties": {
                            "role": {
                                "type": "string"
                            },
                            "content": {
                                "type": "string"
                            }
                        }
                    },
                    "finish_reason": {
                        "type": "string"
                    }
                },
                "required": [
                    "index",
                    "message",
                    "finish_reason"
                ]
            }
        },
        "usage": {
            "type": "object",
            "properties": {
                "prompt_tokens": {
                    "type": "integer"
                },
                "completion_tokens": {
                    "type": "integer"
                },
                "total_tokens": {
                    "type": "integer"
                }
            }
        }
    }
}

Result:

And finally, we can get result and pass it to our app. In my case, I used and expression to get first message from result, and pass it to my app:

first(body('ParseResponse')?['choices'])['message']['content']

Completed flow

The completed flow:

Test from App

Finally, we can create an App to test it. I created a screen with two textbox , firstone for prompt and secondone for output, then I added a button to call our flow and store result in variable.

UpdateContext({ctxChatGPTResponse: ChatGPT.Run(txtChatGPTInput.Text)})

Result:

Power Automate – Get Action Error Details

Posted on 06/18/2023by Angelo

In this article, let’s see how you can catch error during flow executions and send information via email. My way to catch error is by incorporating error handling , and track in log table or SharePoint list on you can also send and email with error details. First of all, if you didn’t , you should read my old article “Power Automate – Try Catch”.

Our Flow

Basically, we have a Power Automate flow with manually trigger who catch wheater informations and log them in SharePoint list.

Power Automate Flow without error handling

According, to my old article. Add “Try Catch” scopes. Our flow became:

In this case, my “Catch” scope, is configured to execute only in case of:

has failed
Is skipped
has time out

Basically, now you can add some action to track if your flow going in error and send alert to users. By, let’s do a little additional step, and get error details.

Get errors details

How can we get error details?

In our “Catch” scope, we shuld add “Compose” block to get output result of our “Try” scope, then, we should filter result to extract error details.

Key Point:

Get “Try” scope result, with compose: (you must use “Get result” action)

result('Try')

Now, use “Filter array” action, to filter “Get-Try-Result” result action. In filter, I added this:

item()?['Status']

and filter for “Is Equal” to “Failed”, so final result is:

Now you can send email with details or track them on list (or both 🙂 ). You can get Action Name, with this expression. To try , I added bool variabile, and set to null in “try” scope.

body('Filter_Result')[0]?['Name']

And error details:

body('Filter_Result')[0]?['Error']

So , final result of “Catch” scope is:

Final result of catch scope with error handling

Final Flow:

Finally, in case of error, here is the detail:

I hope these information can help you! Leave me a comment to let me know what you think, or if you have a better idea to handle this case.

Power Automate – Restore deleted flows

Posted on 01/28/2023by Angelo

Today , I want to explain how you can recover deleted Power Automate flows. PS: If you need recover Power Apps, you can read my article here.

Some note to remember:

You can’t recover your flow if it was deleted more than 20 days ago
You can recover your flow if it was not part of solution (but if did, you can try to open a ticket support)
Default state of recovered flow is disabled
You can recover flow also with powershell commands
You need use Admin user of environment
You can write me for comment to improve quality of my contents 🙂

Create flow to recover deleted flow

Let’s build a new “Instant cloud flow” with manually trigger.

Create new flow — Create new instant cloud flow

Create new flow with manually trigger — Create new instant cloud flow

Now we can add some step to recovery our flow, search “Power Automate Management” and looking for step “List Flows as Admin”, then choose correct Environment and set “Include Soft-Deleted Flows” to Yes.

Now have action to list our flows, included deleted flows. Add “Apply to Each” step (I renamed it “ForEachFlow”) in order to iterate our results and then add “condition” action to filter only “deleted” flow by status property:

Now last step, add action called “Restore Deleted Flow as Admin” set correct Environment (same as step “List flows as Admin”):

and finally run it.

Now , your flow should be appear in list of flow and should be in disabled state:

Considerations

I hope these information can help you to recover your deleted Power Automate Flow…Here you can find official documentation from Microsoft.

Power Platform – Environment

Posted on 11/04/2022by Angelo

Today, we’re going to speak about Environment. Where people starting to create App or Flow, usually, use Default Environment. But in order to have correct governance or our Power Platform solutions, a good idea (but is not only the one) is create more then one Environment. For Example Dev, Quality and Prod.

What is an “Environment” ?

According to Microsoft , and Environment is a a space to store and share data, app , flows. You can image it as a “Container”.

Each environment can have a single Dataverse DB (but you can create environment withoud it)
Default environment is Shared by all users, in my opinion you shouldn’t use it to develop critical app.

Environment types

Basically we can create 4 kinds of environment.

Sandbox: used for non-production environment but for developing and test. It can be reset or copy.
Production: used for permanent work. You need Power Apps license to create and manage it. It will provided with 1 GB database capacity.
Trial: used for short term testing. It will be cleaned automatically after 30 days. I usually use it to try new features. It can be create also as subscription based, and it can be conferted as production environment.
Developer: you can create a developer plan, follow this one.

Create new Environment

Go to Power Platform admin center: Power Platform admin center (microsoft.com) and click on “New”:

Now you can fill option and create your new environment

You can find usefull information here.

Power Automate – Get items – Filter by lookup columns

Posted on 03/06/2022by Angelo

Today, let’s understand how to filter SharePoint Items, by lookup column, from Power Automate flow.

FILTER BY LOOKUP COLUMN

In this Example, I created two lists: Projects and Tasks. Every tasks has lookup to project.

filter-by-lookup-projectlist

And Tasks:

tasks

As we can see , we have “Project” column. This is our lookup column.

Create a flow

To to this example I create a Simple flow wiht manually trigger (keep mind…this is just an example…). My flow has one Actions (“Get Items”). Let’s see how to filter task by Project. One way is filter by title column of lookup (In this case I used Title). Another options is filter by Lookup ID.

Code to copy, filter by Value

InternalFieldName/Title eq ‘Lookup Value’

Or, filter by

internalFieldName/Id eq ‘Lookup Id’

Let’s see our flow:

get-items-lookupfilter

Result: It get me one task, associated with “Project 1” .

lookup-filter-result

Have a nice day!

Power Automate – SharePoint Get Items – Filter

Posted on 09/14/2021by Angelo

Power Automate – SharePoint Get Filtered Items

With this article I want to explain how we can get items with Power Automate (From SharePoint Online) and Filter them.

We have:

SharePoint list’s called “Offices” ,with some data:

Excel file where we save filtered items. I create and Excel file with same column of list, and store it in OneDrive. Keep mind, you must format sheet as a Table if you want to use it in Power Automate to add rows.

Power Automate flow who get data and put it into Excel File. I used “Get Items” connector to retrieve data from SharePoint list.

Get Items

No Query

We can get data with no query. In this case, you mus put only “Site Adress” and “List Name Parameters”…keep mind “Top Count” parameter and it returs “All” items. I do not suggest this approach (And also Power Automate, who show you a Warning 🙂 )

Filter Query

Best approach, is write a Filter Query to retrieve only items you need. Basically you should write a formula like this: fieldname operation value.

As fieldName you must use iternal field name of SharePoint (Write me a comment if you need a post on this argoument).
Operation available are:
- eq (Equal to)
- lt (Less Than)
- gt (Greater Than)
- ge (Greater than or Equal to)
- le (Less than or Equal to)
- ne (No Equal to)
Value: value to find, date and string must be inside ‘

We can use also logical operator like “and” and “or”

Let’s see some example (I show query and result on Excel sheet):

Filter “eq”

Result:

Filter “lt”

Result:

Filter Query with Functions

You can also use functions for your filter query.

endswith
startswith
substringof
….

The syntax is: functions(fieldName, value)

An Example:

Result:

I hope it help you

Power Automate – Try Catch

Posted on 07/02/2021by Angelo

Hi, Today I want to explain how to implement “try-catch” (and “Finally” also if you need). It’s very simple…basically you should add “scope” , put actions inside, add another “scope” to manage error…let me show:

1) Add “Main” scope with your actions inside:

2) Add another scope. I called it “Catch” …it contains some actions to execute if error in “Main” scope should occur:

Now, we must configure “Run after” on this scope to execute it in case of error:

If you want , you can add also “Finally” scope to execute some actions in any case…your flow should be appears like this:

That’s all! Personally I use these scope to write log in case of error and success also.

Thanks
