Order Response

In the order response, you will receive a number of fields that are important to note of, such as the swapType, slippageBps, etc. The main fields you should need:

  • requestId: The request ID of the order to be used in the Execute Order endpoint.
Now, you are able to get a swap order, next steps is to make a post request to the Execute Order endpoint. Let’s go!
