@2WeltenChris
I'm working on connecting up to a Swagger API from SensorPush (Documentation: [Gateway Cloud API — SensorPush](https://www.sensorpush.com/gateway-cloud-api)). I'm having some troubles figuring out how to do the Authentication and Authorization Process prior to pulling in data from the API. None of the examples that I can find show that authentication process. Any advice on how to set things up in this scenario?

Hi @ryanprel
Given this API seems to be using OAuth2, my goto is the OAuth2 Node.
> **[node-red-contrib-oauth2](https://flows.nodered.org/node/node-red-contrib-oauth2?ref=geeek.org)**
>
> The node-red-contrib-oauth2 is a Node-RED node that provides an OAuth2 authentication flow. This node uses the OAuth2 protocol to obtain an access token, which can be used to make authenticated API requests.
Steps.
- Use The OAuth2 node to grab a token (requires the URI, Username, Password, Intent)
- Use the returned token in subsequent calls to the API (Dedicated Nodes, HTTP Node etc etc)
The OAuth2 node works really well.

Hi @ryanprel,
as I have no account for that API this is theoretical, but should work like this:
Get your token by using this operation with your email and password.
EDIT: You will receive an token which must be used with the AcessToken Api.
The token received should be put into into your header -\> you can use the new custom header function in the "advanced tab". Like the image below.
Be aware: Saving the email/password/token as a string means it will be saved in your flow.json. I recommend using env variables for your login (email and password) and saving the token temporarily into the flow or global context.
PS: This operation should get you the access token directly

Sorry - wasn't online in the forum for some time. Did you manage to fix your problem? If not, feel free to open a ticket in gitlab.
