400 Bad Request with delayed api key

[spenouser]

Hi,
I'm able to get a session token from https://identitysso.betfair.com.au/api/login but when I make a follow-up request it gives a 400 error.
My follow up request looks like:

POST https://api.betfair.com/exchange/bet...istMarketBook/
X-Application: RYsbRhPsjnZ0jiJe
X-Authentication: the-token-from-login
content-type: application/json

{
"filter": {}
}

any help is appreciated

Hello, I think you should ensure that you have included all the required headers and that their values are correct. The headers you provided in your example (X-Application, X-Authentication, content-type) seem appropriate, but make sure the values are accurate.
