PowerApps Portal Advance Form Purchase Metadata

Posted on by arslanarif

Good Day. Thank you for you interest.

I am working on a integration with PowerApps Portal (D365 Sales CRM) with PayPal payment Gateway. The scope of the project is to be able to process payments on products inside D365 Sales and track Orders and Invoices.

In Portal Management > Advanced Forms > Advanced Steps > Related > Metadata > There is an option of "Purchase". I was wondering if anyone had any information on this. Attached is a Screenshot of the features available for this metadata. Any information would help.

Best Regards,
Arslan

Hi @arslanarif

I am not sure about that. You can take a look at the following article to set up a payment gateway

Also, did you see the portal templates? You can utilise the customer portal. This will allow you to place the order.

Hope it helps.

If you have to authenticate with Payment gateway then suggest you implement a Companion App and the OAUTH grant flow from Portal.

Your API will provide a PaymentRequest endpoint (for portal requests) and a PaymentResponse endpoint for the gateway's response.

You can then process the payment result, save/submit your record from within the API and respond back to the portal.

This way you handle the payment integration outside of portal - in the custom API.
Use OAuth 2.0 implicit grant flow within your portal - Power Apps | Microsoft Docs

and a sample of a Web App that implements the OAUTH.
GitHub - eugenevanstaden/d365-portal-companion-api: Sample API demonstrating how to configure OAuth to authenticate against D365 portal

This way you dont have to expose your payment gateway keys and config in the portal's javascript!

For example, this code block in Javascript will leak your gateway key!

"Purchase" is a legacy item. Microsoft bought the Portal code from AdxStudio, and Adx had integrated payments (that MSFT have not resurfaced after buying the code). https://adx-community-eus.azurewebsites.net/products/adxstudio-portals/documentation/configuration-guide/web-forms/web-forms-metadata/

The better way to write your own would be to use oAuth Explicit Grant flow as suggested in the previous post - but technically you can do it for payment providers that allow you to embed JS, the difficulty is that you generally need to provide a callback url (payment confirmation etc) you can use a REST/HTTP Flow but it is painful to make this truly secure.
