Cannot used Customer Connector to call API with the Post Method

Posted on by luckytran

Dear Community,

I created the Customer Connector to connect my customer's API with the POST method (the body is JSON with many levels). I tested the connection successfully.

When I used this customer connector to put the result in text input or text label, I get the issue "Behavior function in a non-behavior property. you can't use this property to change values elsewhere in the app".

I attach the picture issue

I'm looking forward to hearing from you.

Regards

Tuan Tran

Hi @luckytran :
Firstly,let me explain why you encounted this problem.
Your code SCBAPI.GETSCBAPI(……) is a behavior function,but text property is a non-behavior property.Therefore, the app will report an error.
Secondly,I suggest you try this solution:
Put this code in a behavior property and assign its value to a variable.
1\Set the apps OnStart property to:

Set(Var,SCBAPI.GETSCBAPI(……)) /*Var is a custom variable*/

2\Set the lable control's text property to :

Var

Hi @v-bofeng-msft

Thank you for your reply.
I tried your guide but Text Label didn't display the result.

I set a variable value at Screen - OnVisible.
After that, I set the attribute "Text" of Text Label is this variable - ApiData, but didn't display the result

Please help me with this case.

Hi @luckytran :
I suggest you put this code in OnStart property and select "Run OnStart" to test it.
If there is still no result, please check whether your custom connector is configured correctly, and check your code for problems.

Hi @v-bofeng-msft

Thank you for your support. I used the onSelect attribute of the button and I can get the POST method result.

I have one more question. How can I get the status (httpcode) when I call API.

Hi @luckytran :
You can see ‘Status’ after clicking “Test operation”, but it seems that it cannot be called directly in the canvas.
