ERROR: [Skyflow] Interface: init - Invalid token is generated from getBearerToken callback

[toshunigam]

Hi,
I am using this skyflow react package in my application and i am getting error of invalid token generated from getBearerToken when i click on collect submit button.

It was working earlier but from last 2 days it is started giving this error

const handleCollect = () => {
setIsWaiting(true)
const response = container.collect();
response.then((res) => {
let amount = JSON.parse(localStorage.getItem('amount'))
let cvv = JSON.parse(localStorage.getItem('cvv'))
let param = {
card_number:res.records[0].fields.card_number,
card_exp_month:res.records[0].fields.expiry_month,
card_exp_year:res.records[0].fields.expiry_year,
amount:amount.value,
card_cvc:cvv.value,
skyflowid:res.records[0].fields.skyflow_id,
card_holder:res.records[0].fields.cardholder_name
}
// console.log(param)
submitPaymentDetail(param) // This is my function which i am calling to store the tokenize value into my DB getting from skyflow
}).catch((e) => {
setIsWaiting(false)
console.log(e)
})
}

NOTE: I am using skyflow Quick Guide for this.

Please help me

Hi,

The above error is thrown when the getBearerToken callback returns an invalid token (or) if the returned token is expired.
Also please check the service account used to generate the token

Hi Shaik
Thank you for reply.
As i can see that the Service account is active and also i was not sure where to put the bearer token in client panel like here in react JS. It was working earlier but now it doesn't
May doubt is.

1. Do i call have to call skyflow api for bearer token. [what is the dedicated endpoint for this from skyflow]
2. OR i have to keep it some where in my project environment. [then what if the token is expire]
   Please suggest

Thank you in advance

Hi

Since React SDK is a client-side SDK the token generation depends on the user, which means that the user can define a custom endpoint that takes in the service account details and generate the bearer token. And this custom URL should be passed to React SDK as described in the sample here https://github.com/skyflowapi/skyflow-react-js/blob/master/samples/SkyflowElements/src/index.tsx#L30

We support bearer token generation methods in our server-side SDKs in Node, Java, Go, and Python.

1. We have a dedicated endpoint to get the bearer token https://docs.skyflow.com/management/#AuthenticationService_GetAuthToken ( Please sign in to docs using your skyflow account credentials )
2. Instead please use a server SDK like Node SDK( https://github.com/skyflowapi/skyflow-node#service-account-bearer-token-generation ) to expose an token endpoint and then use that endpoint in React SDK

Hope this answers your questions

Thanks

Actually we are using Laravel as a backend and for this there isn't any sdk or CURL for generating bearer token.

Anyway Thank you Shaik for clearing the doubt.

Hi Shaik,
As i can see there is a cURL and that we can use in our laravel backend.

curl --request POST
--url https://manage.skyflowapis.com/v1/auth/sa/oauth/token
--header 'Authorization: REPLACE_KEY_VALUE'
--header 'content-type: application/json'
--data '{"grant_type":"string","assertion":"string","subject_token":"string","subject_token_type":"string","requested_token_use":"string","scope":"string"}'

But Not sure about this 'Authorization: REPLACE_KEY_VALUE'

can you guide me from where do i get this also the --data fileds as well

Thank you

Hi,

In production environments, we recommend you generate bearer tokens using Skyflow-provided SDKs.

Here's a guide to using a Python script to generate a signed JWT and use it to call the Get Bearer Token endpoint. https://docs.skyflow.com/api-authentication/#use-a-python-script.

1. The Authorization header is not required for calls to Get Bearer Token.
2. You can use the getSignedJWT function from the Python script to create a signed JWT to pass as the body parameter assertion value. For grant_type, you can supply the string value as shown in the API Docs and Python script: https://docs.skyflow.com/management/#AuthenticationService_GetAuthToken. As with the getBearerToken (line 31) function in the Python script, only grant_type and assertion are required body parameters for the Get Bearer Token endpoint.

Thank you!
