Posted on by Community Power Pla...

I am new to Power Apps and Power Pages. I am attempting to build a simple power page that will had a text box and a button on the page. The user will in put text in the text field and click the button. The action I would like to be performed on button click is to pass the enter text to an existing web service and to either redirect to a new page showing the results from the web service call (or possibly within the same page).

I am struggling to determine where to start.

I am looking at the basic form and advanced form but it is asking to be based on a dataverse table.

Would the web service call be some form of a flow trigger by the button?

I am simply looking for pointers on where to dig into documentation. I have been googling this all morning and I seem to go down rabbit holes that end up having nothing to do what i am looking for.

Re: Create a form that connects with an external Web API

Hi @Anonymous

Yes, there are a few ways to achieve this. Some of the frequent use are on a high level

1. You can use dataverse connector - create/modify the record and use HTTP premium action then call your external API.

2. On a basic / Advanced form > advanced > Custom JavaScript > you can write an ajax call to call your external API

3. You can build your custom PCF component if you want what you are trying to achieve.
