Getting an error while trying to pull the data from ServiceNow into my React App using REST API

[Chandra Mouli]

Hi Team,

I am trying to connect ServiceNow platform to my React app using REST API. However, I am getting error message.

Below is the piece of code for reference:

Note: I have tested the API using "Postman" and it is working fine without any issues(Credentials are correct).

const Fetchincidentdata = useCallback(async () => {

    try {

      const url = "https://dev72953.service-now.com/api/now/table/incident";

      const username = "****";

      const password = "******";

      const response = await fetch(url, {

        mode: "no-cors",

        method: "GET",

        headers: {

          Authorization: "Basic" + btoa(username + ":" + password),

          //'Accept': "application/json",

          "Content-Type": "application/json",

        },

      });

      const data = await response.json();

Attached the error screenshot for reference:

Please check and help.

Thanks,

Mouli

@Chandra Mouli 

can you share how you configured the REST message in ServiceNow?

Also share the scripts and screenshots.

Hi,

Thanks for responding.

I didn't configured any REST message. I am using "REST API Explorer" for checking the connectivity.

I tried with the API that is created upon clicking "Send".

Note: Able to fetch the data using Postman..

Please let me know if you need any further details.

Thankyou,

the error is http 401 -> meaning wrong user name and password combination

Hi @Ankur Bawiskar 

I have used the same credentials in postman and it is working as expected.
