Pass parameters to custom API

[jl_144432]

Dear community,

I am new to powerapps and want to ask if I could achieve the following functionality:

- let user input some data and after that, send those data as parameters to my custom API with a POST, so that my backend can receive those data as string as manipulate them.

I know that with text input I can save the string as a variable, but I don't know whether is possible to send it to my API endpoint.

Thanks in advance!

Hi @jl_144432 ,

Custom connector can meet your needs.

After the custom connector is created, create a connection.

Add the connection to the canvas app, and finally use the formula of the custom connector and enter the parameters.

Thanks for the reply, that also works with a table template right? And where could I replace the string by my variables?

Hi @jl_144432 ,

Do you mean you want to pass a table parameter instead of a string(text) parameter?

If my understanding is correct, you could use the table() function:

Table({Column1:"A",Column2:"B"},{Column1:"C",Column2:"D"})

nono sorry was saying tablet. I mean where should I put the input parameters as variables? Imagine that I have an api endpoint that connects to api function getweather(string city) and returns me the weather(a string), where should I put the city input?

Hi @jl_144432 ,

I may understand what you mean.

So, according to your description, you are using a get api instead of a post api.

You only need to enter the correct URL with query, and the custom connector will automatically recognize the input (string city).

Hope this link will help you.(This is a weather Api. When you enter a city, it will return the weather of that city)Here

This does work... in my swagger I defined the parameters that are acceptable and then in my button.onSelect  I called my API and passed in the parameters.  I was distracted with having to creating a JSON for the body, but it looks like power apps does that for you behind the scene.  My solution looked something like this:

testAPI.updateQuestion({id:"123", Description:"aa", CreatedBy:"c", QuestionNumber:"1", QuestionText:["a1","a2"], Education:{Title:"t",URL:"tu", Type:"t"}})

now all I need to do is replace the values with the actual form values such as:   TI_Description.Text
