Sending Multiple Orders

[BigSprout]

I am having a problem sending multiple place orders, if I send the orders individually I get a "success" response, but when I put them together I get a " -32602" error (Problem parsing the parameters, or a mandatory parameter was not found).


This is 2 orders sent separately:

{"jsonrpc":"2.0","method":"SportsAPING/v1.0/placeOrders","params":{"marketId":"2.101255430","instructions":[{"selectionId":9172548,"handicap":0.0,"side":"LAY","orderType":"LIMIT","limitOrder":{"size":5.0,"price":1.01,"persistenceType":"LAPSE"}}],"customerRef":"ABC"},"id":1}

{"jsonrpc":"2.0","method":"SportsAPING/v1.0/placeOrders","params":{"marketId":"2.101255430","instructions":[{"selectionId":8564429,"handicap":0.0,"side":"LAY","orderType":"LIMIT","limitOrder":{"size":5.0,"price":1.01,"persistenceType":"LAPSE"}}],"customerRef":"DEF"},"id":1}

This is the request sent for the 2 orders as a multiple place order request, I get the -32602 from this:

{"jsonrpc":"2.0","method":"SportsAPING/v1.0/placeOrders","params":{"marketId":"2.101255430","instructions":[{"selectionId":9172548,"handicap":0.0,"side":"LAY","orderType":"LIMIT","limitOrder":{"size":5.0,"price":1.01,"persistenceType":"LAPSE"}},{"selectionId":8564429,"handicap":0.0,"side":"LAY","orderType":"LIMIT","limitOrder":{"size":5.0,"price":1.01,"persistenceType":"LAPSE"}}],"customerRef":"XYZ"},"id":1}

If someone could show me where the error is it would be much appreciated

Reading my post, I may have been a little too cryptic, so for a fuller explanation:

I have been sending individual orders which have been successful, but when I tried entering more than one "instruction" to a request I received the error.

If my single instruction is sent in a request, these are a SUCCESS:
request_1
"instructions":[{"selectionId":9172548,"handicap":0.0,"side":"LAY" ,"orderType":"LIMIT","limitOrder":{"size":5.0,"pri ce":1.01,"persistenceType":"LAPSE"}}]

request_2
"instructions":[{"selectionId":8564429,"handicap":0.0,"side":"LAY" ,"orderType":"LIMIT","limitOrder":{"size":5.0,"pri ce":1.01,"persistenceType":"LAPSE"}}]



I thought by including both the orders in the one instruction as a multiple place order, all I needed to separate the orders was by using a comma, as such:
"instructions":[
{"selectionId":9172548,"handicap":0.0,"side":"LAY" ,"orderType":"LIMIT","limitOrder":{"size":5.0,"pri ce":1.01,"persistenceType":"LAPSE"}},
{"selectionId":8564429,"handicap":0.0,"side":"LAY" ,"orderType":"LIMIT","limitOrder":{"size":5.0,"pri ce":1.01,"persistenceType":"LAPSE"}}
]

My question is - how do you add multiple orders to the one request?
I have removed the front and rear end of the Json request for clarity, actual Json Request are as per my original post.

These are examples only

Human Error due to finger troubles

Finally found my error,
When automating my multiple Place Order requests, I had used "Lay" instead of "LAY", so my system worked on manual but not on automatic.

My problem was in my haste to display my Json requests/response, I had used copy/paste of the manual (good) orders.

All is good now.

My apologies to any inconvenience caused with ppl trying to locate a fault.

Cheers (will now go and crawl back into my hole)
