Chatbot integration with Blue Prism

vinodchinthakin — Wed, 28 Apr 2021 08:32:00 GMT

Hi,

We are trying to create a chatbot using tools which are available online, then wants to integrate with Blue Prism.
Now we have created a flow in Microsoft Power virtual agent , facing issue while integrating with Blue prism using api (which is downloaded from DX), can any one help in fixing it.

Does anyone know any chatbot tool which can be integrated with blue prism.
pls share some articles or video url's for reference.

thanks in advance

@vinod chinthakindi,

You mention an issue with an API you downloaded from the DX. Which API are you referring to? Generally, to integrate with Blue Prism from an outside application you're going to do so by invoking SOAP services which are processes or VBOs you expose from your BP environment.

Hi @ewilson

we have downloaded "MicrosoftPowerPlatformConnector" from DX. we have followed Integration Guide as it is. we have exposed BP process as SOAP web service. and tried to create a connector in power automate. when we are calling an API post request we are facing an error " 401 or 400".

Please find attachment for error message.

Pls suggest us any solution.

@vinod chinthakindi,

401 is an unauthorized response. I imagine you're getting that because you're missing some credentials. When you expose a Blue Prism process/VBO as a SOAP service you have to supply credentials to actually invoke them, and they have to be supplied as HTTP Basic Auth. These credentials would be something you've defined within your Blue Prism environment. In other words, the username and password for a Blue Prism user account that has permission to execute said process/VBO.

Cheers,

Hi @vinod chinthakindi,

It's not clear to me, from the screenshots, whether Power Automate is actually sending those credentials as HTTP Basic Auth. Give the 401 response, I'd say probably not. You might try running Fiddler or Wireshark to capture the network traffic. Then we can see the actual HTTP request along with the headers and see if there is an Authorization header included.

Is you Blue Prism environment running in an Azure instance or on-prem? Something else that could be happening is simply a firewall blocking access to the BP instance from the outside world.

Hi @ewilson
Blue Prism environment running in on-premise.
1. How to identify in firewall which one is blocking BP instance.?
2. Do we need to install any SSL certificates?
3. I have used http://machinename:8181/ws/addition?wsdl as end point. Is it correct way to use end point in Power VA?
4. provided process name as addition and resource name as machinename. Is it right?

@vinod chinthakindi,

See the below thread regarding calling SOAP web services within Power Automate.

Hi @ewilson

We have gone through the thread that you shared. But we weren't solved the issue.
If we are hitting this request URL "https://powerplatformconnector.azurewebsites.net/api/BluePrismRestInterface" on Postman we are getting error 404 resource not found. This request url automatically generated when we imported Blue-Prism-v2.swagger Json file.

@vinod chinthakindi,

This is a bit confusing. Originally, it sounded like you were having issues calling a Blue Prism process/VBO from within your Power Automate flow. Your most recent post says you're getting a 404 when you try to call an actual Power Automate endpoint which is completely different. Have you published an Azure Function for this endpoint?

Hi @ewilson

We have published an Azure Function. The host powerplatformconnector20210427122451.azurewebsites.net is working fine.
Is this the correct host of power automate?
If possible, can we jump over a quick call.

Vinod,

If you are running Blue Prism in an on-premise environment, then you will have some challenges. The Power Platform Connector communicates with the Azure function, which it turn invokes the Blue Prism SOAP service of your process. The Azure function is in the cloud, and natively has no way of communicating with your on-prem Blue Prism instance. There are a couple of suggested approaches:

1) You can run your Blue Prism instance in Azure alongside the Azure function
2) You can install the Power Platform Data Gateway to allow on-prem accesses from cloud native resources (https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/gateway-reference)
3) You can run the Azure function on a local IIS Server and make the rest endpoint publicly accessible to your Power Platform Connector

Hopefully one of these scenarios will support your requirements.

Hi @ChrisHogan

Thanks for sharing the articles. We are going with second approach using data gateway.
we have installed data gateway and configured with the steps mentioned in the url. But the data gateway is not visible in the power automate.
pls refer attached screenshots.

Hi @ChrisHogan @ewilson

1) You can run your Blue Prism instance in Azure alongside the Azure function
We have created BP instance in Azure and created a custom connector by importing blueprism swagger api. while testing we are getting an 400 error
message": "A connection attempt failed because the connected party did not properly respond after a period of time,
or established connection failed because connected host has failed to respond. A connection attempt failed because the connected
party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."

2) You can install the Power Platform Data Gateway to allow on-prem accesses from cloud native resources
we have installed data gateway and configured with the steps mentioned in the url. But the data gateway is not visible in the power automate.

Pls refer previous attachments.

Can you guys pls suggest some solution?

So ... when I faced this situation I used the IBM gateway restricting only to the link of my exposed process, with that I was able to expose the link to Azure and to be able to use the service bot, it is worth the try ..

Hi @EmersonF

I have a query, Is Service bot API free to use or needs to pay for that?
can you help us integrate Service bot with Blueprism using API?

Thanks in advance...

vinod, today azure service api is not free you need to have an active subscription.

What I recommend you do. Create a process that rotates in background mode that will be responsible for orchestrating your execution, after you create this process, right after you can expose this process to have access to wsdl and instead ibm security gateway to be able to export this endpoint on the network and call this new end point in your chatbot and pass the necessary parameters, this is one of the paths I follow.

Hi @EmersonF

Thanks for the suggestions.

We were stuck in the middle of the integration, so we need some help that can be discussed by screen sharing.
Is it possible to jump over a call. Pls can you share your id, so that I can send you a request.

Thanks in advance...
