1. Send the RFQ session request event to create an RFQ session. The server responds with Successful RFQ session response, indicating that the RFQ session has been created. The service sends requests to external providers (from the list specified by the client in the request). Upon receiving an answer from any provider, the server sends a Quote response.

RFQ session request

{
"event": "CREATE",
"reqId": int,
"instrument": string,
"providers": int[],
"side": string ("BUY"/"SELL"),
"size": int
}

For getting providers use:

"reqId": int,
"status": string, ("SUCCESS", "REJECT", "ERROR")

"quotes": [
   {
     "side": string ("BUY"/"SELL"),
     "price": int 
   } 
 ],
"error": string
}

1. Send an Order confirmation request to approve the deal with the provider specified in the request. The server sends another request to the specified provider, and depending on its response, the server can respond with an Order confirmation response with different statuses:

   • SUCCESS if the provider approved the deal.

   • REJECT if the provider rejected the deal.

   • ERROR if there was an error during the request.
