Trying to make call to API-2 from Auth0 Flow using HTTP Request  
In the body, I need to pass a Boolean value to API-2 which is received from the response of API-1.

{  
“email”: “{{context.user.email}}”,  
“userId”: “{{context.user.user\_id}}”,  
“lastName”: “{{fields.lastName}}”,  
“isReturningMember”: **{{actions.http\_request\_my\_details.body.data.isReturningMember}}**  
}

It gives error for isReturningMember - “Body is not a valid json” because I am not enclosing them in the quote.

If I update it with quotes to “isReturningMember”: **“{{actions.http\_request\_my\_details.body.data.isReturningMember}}”** , the flow works but API-2 fails because it is expecting boolean but string is received in the request body.

How to fix this?

Hi @rbAuth0,

Can you tell me what is the value of **{{actions.http\_request\_my\_details.body.data.isReturningMember}}** is?

Have a good one,  
Vlad

For others facing similar issue, the solution is  
“isReturningMember”: “{{functions.toBoolean(actions.http\_request\_personal\_details.body.data.isReturningMember)}}”

Use functions.toBoolean and use quotes as well.
