Parse JSON Assistance

(0) ShareShare
ReportReport
Posted on by

Hello,

When creating Custom Connectors in PowerApps, I can just paste a Postman response Body into the "Sample" area and PowerApps automagically parses out the items I need with the correct labels. 

 

With Flow, this is not the case. Pasting a Response Body from Postman required manual cleanup to pass validation. Now that it passes validation though, I can't tell the parameters apart.

 

Many of them are just labeled "type" due to how Flow parsed the Sample Payload. 

 

How can I get the correct labels for each parameter of the JSON payload?

 

Thank you!

 

Postman response Body:

    @mosmas (aka "Flow Poppa", aka "Flow Maestro", aka "Flow Magic", aka "Don't Call Me On The Weekend" 🙂 )comes through with the fix!!

    Key 1:  

    • Read the failure message and fix the schema!
    • "features.properties.gap" in this case is the path in the nested JSON where the error is occurring
    • image.png
    • One caveat that @mosmas  brought up is when a value can have BOTH a number (or string) AND a NULL. 
      • It needs special treatment: ["integer", "null"]
      • Example:
      • image.png

    Key 2: 

    • Once the schema passes validation, use the Select Action to create a sweet little array of each object

    BONUS!!:

    • You can search your Parse JSON sample schema with CTRL+F
    • image.png

    Thanks so much @mosmas !!

    @KickingApps , this is a good one to play with!

    BONUS BONUS!!

    • Did you know you can change the names of parameters returned from an HTTP request as part of parsing JSON!
    • WOW
    • Example
      • There are two keys named "url" in the schema 
      • image.png
      • You can rename them IN THE SCHEMA to differentiate them!
      • image.png
      • This is crazy powerful!!

    Again, all praises go to @mosmas !! Excellent work and thanks for sharing the expertise.
