Cancel incoming payment

[Former Member]

Hi experts.

I need to cancel an incoming payment using service layer. I don't know if is this posible but I've been able to do this using di api so I think it should be posible in this way. I'm using Postman to test it, this si my code:

PATCH /https://xxx.xxx.xxx.xxx:50000/b1s/v1/IncomingPayments('1155')
{

"Cancelled":"tYES"

}

I'm getting this error:

{ "error": { "code": -1000, "message": { "lang": "en-us", "value": "Bad Request - Error in query syntax." } } }

I hope you guys can help me. Thanks a lot.
