My question is related to node red openapi client i have used "npm install openapi-red" to install openapi red.  
I am using openapi client to show my result but it shows an error of

```auto
 {
   "error_message" : "You must use an API key to authenticate each request to Google Maps Platform APIs. For additional information, please refer to http://g.co/dev/maps-no-account",
   "results" : [],
   "status" : "REQUEST_DENIED"
} 

```

so i add key value on function node using

`msg.openapiToken=" hdgfuiehedjwenishuiew" `

(it's just an example) but it still shows the same error as i mentioned above so i  
tried

`msg.headers = { "key" :"key_value"}`

but still shows the same error . So please tell me what should i do to solve this error or what i have to use to resolve this error.

Do you have a valid [API key from Google](https://developers.google.com/maps/documentation/javascript/get-api-key)?

> ## Create API keys

> The API key is a unique identifier that authenticates requests associated with your project for usage and billing purposes. You must have at least one API key associated with your project.

I edited your first post so it would be easier to read, Hopefully someone with knowledge of the Google API will chime in (I don't use Google)

The documentation of the node describes:

> 1. Authentification

> If the API requires an authentification token you can log in using the standard `http-request`node of Node-RED. The JWT token you get as a response must then be put into `msg.openApiToken` to be automatically placed in the request-header as bearer authentification. In case you would like to use a different authentification than bearer, you can use `msg.headers` as you can do with the default http request node of Node-RED.  
> Both message object will be deleted afterwards if you do not set the option "Keep authentification".

In short:

- first post a request with your key to the API.
- the response will be a JWT token.
- the JWT token needs to be provided to the open-api node as `msg.openApiToken`
