How to pass received SecurityToken into the header's security section?

Hi all,

What should I do to pass a received SecurityToken/DigestValue/SignatureValue/X509Certificate into the header's security section in order to pass the security test?

Using an API of rechtspraak.nl (https://sts.rechtspraak.nl/adfs/services/trust/13/usernamemixed) I passed a username&password into the header's security section. I received back the Assertion containing these items: SecurityToken/DigestValue/SignatureValue/X509Certificate. Now the security-section allows for these sections: TimeStamp,
BinarySecurityToken, BinarySecuritToken, UsernameToken, Assertion, EncryptedKey, Signature

Now I am trying to consume the rechtspraak.nl's api https://curateleenbewindregisterservice.rechtspraak.nl/CcbrDataservice.svc but am still unsuccesful in getting the security right. Can anybody tell me what value to enter in what section to get past the security?

Best regards,
