Condition if body contains

Posted on by Rubenfrreis 23

Hi all

I'm building an application in Powerapps that uses an API, the request will confirm if the input user already exists.

Basically everything is working, but the condition is not...

 

The API respond if a user does not exists:

body: []


If the API respond with a full json if the user exists

 

My flow condition is like: If body contains variable"email@contoso.com" 

But he is not detecting the variable "email" in the JSON response, I even added LESS THAN 3

to separate the true or false, because if the user does not exists the response from the API is "[]"

    Hi @Rubenfrreis ,

    This seems a PowerAutomate question rather than a PowerApps one, but let me give a try. 

    My thinking is to insert a new action Parse JSON with body as input value and the schema given by the JSON API response format. 

    Then in condition: use the length() function for "email" column from Parse JSON  equal to 0.

     

    Hope it helps !

    Thank you for the reply,

     

    Using the Parse JSON and after that, point to the email field and make check if it is equal to variable (email@something.com), flow transform the process to Apply to Each because is a JSON field.

    It is not possible to send response to powerapp with Apply to each, and I'm struggling in here.

     

    The api respond with a Json format where one of those format is:

    First name: email

    Last name: test

    email: email.test@something.com

     

    If the user does not exists, it basically reply with a Json:

    random stuff and with the body:

    "Body":[]

     

    I want to send a message back to the app if the user already exists.

    I can use the email from the json to compare it exists, but I can't respond to powerapp
