As I understand ZOHO functions cannot handle multilevel or nested JSON strings.  So I have had to create my JSON string manually.  I believe the string to be formulated correctly, however when I run my custom function I get the following response in return>

"responseCode":"400","responseText":"The request had bad syntax or was inherently impossible to be satisfied."

I am pretty confident that my JSON is formatted correctly for the required POST>

Here is the documentation link>

https://developer.paypal.com/docs/integration/direct/create-single-payout/

Here is a sample of my HeaderMapVariable (with Access key scrubbed)>

{

• "Authorization":"Bearer A101.GlaVuJsANIf8zietZFUNaaxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.Ikb28Df63uYCiiWSwrL142u0B_8",
• "Content-Type":"application/json"

}

Here is the detailJSONString - created by combining strings as multilevel/nested JSON is not supported

{

• "sender_batch_header": {
  • "email_subject":"Great News: Payment Received from US",
  • "sender_batch_id":"12345678",
  • "recipient_type":"EMAIL"
  },
• "items": [
  1. {
     • "recipient_type":"EMAIL",
     • "amount": {
       • "value":"100.00",
       • "currency":"USD"
       },
     • "note":"Thanks for working together with us",
     • "sender_item_id":"1234567",
     • "receiver":"nickbh@n.co.uk"
     }
  ]

}

Here is a the call I make from the function>

//

//

PayPalAPIResponsePayout = postUrl(" https://api.sandbox.paypal.com/v1/payments/payouts?sync_mode=true",detailJSONString,HeaderMapVariable,false);

info PayPalAPIResponsePayout;

//

//

As I said, I get the following response>

"responseCode":"400","responseText":"The request had bad syntax or was inherently impossible to be satisfied."

Ive been looking at the issue for ages.  I have tried loads of debugging, but cannot find the issue. 

I have made other calls to PayPal - the first one was to get the access-token and that works fine.  the only diffrence is that that call uses all maps() and not a string I have created. 

Any help greatly appreciated.

Thanks
