Im getting a 400 error when trying to request things

[sadasdasdasdad]

Hey everyone,

I'm trying to request data via the API. I'm using a Java + Spring App for that. I'm able to login/logout successfully. But whenever I try to send a POST request against the REST API, ill get an 400 error and the following message:

{

• faultcode: "Client",
• faultstring: "DSC-0008",
• detail: { }

}

Do any of you have an idea what this could be about? I'll send:

X-Application
X-Authentication
Accept
content-type

as the header and an empty filter as payload with the post request. I'm requesting against the endpoint
https://api.betfair.com/exchange/bet...istEventTypes/ BR/ Matt
