Hi Guys !

i often received this message Authentication credentials were not provided.

please i have been wondering how to add an authorisation API for GET request for HTTP request. on node -red.
i have tried it on Post Man and it works very fine here is the result

[
    {
        "timestamp": "2021-11-22T22:40:00",
        "load_state": "ON",
        "load_w": 148.946,
        "output_wh_total": 4003.0,
        "output_wh_delta": 49.0,
        "solar_w": 0.0,
        "solar_v": 3.832,
        "input_wh_total": 0.0,
        "bat_v": 25.258,
        "state_of_charge": 100,
        "full_charges_count": 1,
        "deep_discharges_count": 0,
        "bat_chg_total_wh": 0,
        "bat_dis_total_wh": 4003,
        "bat_usable_ah": 0.0,
        "bat_temp": 36.148,
        "restart_detected": false,
        "signal_strength": -59,
        "error_flag": 0
    }
]

the API is  `https://cloud-solar.com/api/v1/devices/xokM5P/reports?start=1637620800&end=1637620811`

and the header is ` Authorisation: Token 6d423a90252863e3f4cc068546617b452031d167`

just like this

It depends on what the header needs to contain, but have you tried the 'Use authentication' option in the node?

wow !

thanks for your reactivity.

yes but i don't know the username and the password.
i am only having the unique API KEY

Authorisation: Token 6d423a90252863e3f4cc068546617b452031d167

thanks

Okay - so that isn't a standard format for the Authorisation header, so the node won't be able to set the header for you.

Instead, add a Function node before the HTTP Request node with:

msg.headers = {
   "Authorisation": "Token 1234...."
}
return msg

@knolleary
that is exactly what i did

msg.headers = {
   "Authorisation": "Token 6d423a90252863e3f4cc068546617b452031d167"
}
return msg

but i get this Authentication credentials were not provided.

whereas it works well on post man

Authorisation should probably be Authorization (UK vs US English...)
