Login to API then Poll

MattFancher1 — Tue, 02 Oct 2018 15:27:53 GMT

I want to use the "Poll and External Website for JSON" connector in GeoEvent. The API I plan to poll requires you to first authenticate. Outside of GeoEvent, I have to first post a JSON with username/password to api/export/login. The API returns raw text "true" as a response when authenticated. Next, I have to post another JSON with search parameters to api/export/export. Any advice how to implement that in GeoEvent? I'm currently running version 10.3.1. Thanks very much in advance.

Hi Matt Fancher‌,

On the surface, GeoEvent is capable of passing credentials to authenticate against a certain endpoint. This can either be done through a GET request where the parameters for credentials/token are passed within the URL itself or through a POST where the headers for authentication are specified in one of the input connector's properties. I am unsure if there is a means to send one request, receive the response, and then send another through the connector.

Do you have a means of accessing the endpoint you need in one fell swoop, to where you can bypass the authentication or somehow include it in a single request?

Hi Daniel. Sorry for the slow response. Unfortunately no, the API requires me to first authenticate, then post a separate request in order to access data.
