HTTP Post keeps adding a \ where a "

Posted on by MrRK

I've spent all evening searching for the answer on this one... please help.

I add this into a compose action:

[{"Group":2512276,"TimeSlot":"0"},{"Group":2517214,"TimeSlot":1"},{"Group":2513377,"TimeSlot":"3"}]

When the flow is ran, the body section of my HTTP post action, where the compose is inserted shows:

{
 "Name": "AA - 12220573_637004232000000000CG",
 "CustomerRef": 45345,
 "SiteID": 2243,
 "Access": "[{\"Group\":2512276,\"TimeSlot\":\"0\"},{\"Group\":2517214,\"TimeSlot\":1\"},{\"Group\":2513377,\"TimeSlot\":\"3\"}]"
}

See the screenshot below. How do I stop Flow from adding the \ to my post body?

Hi @MrRK

Looks like your output of compose is fine. It is not adding the '/' character. How do you mapping the body of http? I can see there are other elements in the body such as Name, CustomerRef, SiteID. Could you please show a screenshot of this?

Thanks

Hey @MrRK

For some reason that compose action is getting the input as string and that string is later being serialised in the HTTP action. I tried this by manually creating an array and typing the values in and it worked just fine.

Hope this Helps!

Hi @MrRK ,

I think the advice provided by yashag2255 is correct. You could use the variable of the corresponding type to store the property value, such as an object or array variable. Please take a try.

Best Regards,

You are correct, when the data is manually entered into a compose action, and then added to the HTTP Post, it works fine.

However, try initialising a variable, and setting the same values inside of a string. Then bring that into a http post in the same way, and it gets incorrectly formatted. I've tried everything to stop it happening and nothing works!

Hey @MrRK

You got it there-> "However, try initialising a variable, and setting the same values inside of a string. Then bring that into a http post in the same way, and it gets incorrectly formatted." The moment you add it as a string it will read it as one and add those extra characters to send a serialized body to the API call.

Hope this Helps!

Awesome...

Ideally I'm trying to append to the Variable (String) based on various actions, and so Compose won't work for me.

What is the correct way?

Hey @MrRK

You can go the variable way too. All you have to do is to intialize an array variable and keep appending the objects in that using the append to array variable action.

Hope thsi Helps!
