Hitting Endpoint via External Source

[may-butter]

Has anyone been able to hit their warpgate server's api endpoints via something like Spring? I can't hit those endpoints even after hardcoding endpoints to contain the warpgate target. Are there specific tokens needed and if so, is there a way to get those or fetch them via google functions since we are using Google SSO? For reference I am working in Java and Groovy. My typical endpoint calling kind of looks like this:
def response = httpBuilder.post { request.uri.path = '/api/fetch/info' request.contentType = 'application/x-www-form-urlencoded' requestBody.page = page request.body = requestBody request.encoder 'application/x-www-form-urlencoded', NativeHandlers.Encoders.&form }
