How do you properly call refreshToken() to obtain a new token? about ebay-api

[doverradio]

I see the error. I was using .refreshToken() when I should have been using .refreshClientToken().

After making the change, I got a successful newly generated access_token from eBay.

It's eBay.buy.browse.getItem(), you missed buy.

The token is refreshed automatically if the refresh_token is also set. Instead of storing the access_token you have to store the WHOLE token that looks like this:

{
      access_token: 'accessToken',
      refresh_token_expires_in: 0,
      refresh_token: 'refresh_token', // this is required to refresh the token
      token_type: 'token_type',
      expires_in: 7200
    }

Why are you calling result.json()? The result is already in Json.

Actually you don't even need the Access Token for getItem. Checkout the example here https://hendt.github.io/ebay-api/ maybe it will help you.

Ok and where does the refresh_token get set? During the literal first authorization call?

I will need to know how to do it correctly for other calls. Thank you for guidance on getItem.

Exactly. const token = await eBay.àuth.oAuth2.getToken(code); will return the whole token and you need to store it.
Than you can use something like

let { token } = await User.findById({_id: user});
eBay.auth.oAuth2.setCredentials(token);

Do you mean like this?

let { token } = await User.findById({_id: user})
let { access_token } = token
eBay.auth.oAuth2.setCredentials(access_token)

My bad, I fixed my code should be eBay.auth.oAuth2.setCredentials(token);
And the token has the following structure:

{
      access_token: 'accessToken',
      refresh_token_expires_in: 0,
      refresh_token: 'refresh_token', // this is required to refresh the token
      token_type: 'token_type',
      expires_in: 7200
}

I still have been unable to get this right. I'm trying to refresh a User token. After making changes which attempt to trigger refresh token to be generated, it is giving me an error TypeError: Cannot read property 'refreshToken' of undefined.

Here is my code (expressjs controller method):

exports.refreshEbayToken = async (req, res) => {
  let {        
    token // this is the token as we discussed previously (contains access_code, refresh_code, etc.)
    } = req.body

    try {

      eBay.auth.oAuth2.setCredentials(token) // sets the token with expired token

      let post = {
        RequesterCredentials: {
          eBayAuthToken: token[0].access_token 
        },
        Item: {
          Title: `Harry Potter and the Philosopher's Stone`,
          Description: {
            __cdata: `<div>This is the first book in the Harry Potter series. In excellent condition!</div>`
          },
          PrimaryCategory: {
            CategoryID: "377"
          },
          StartPrice: 30,
          CategoryMappingAllowed: true,
          Country: "US",
          Currency: "USD",
          ConditionID: 1000,
          ItemSpecifics: {

                value: "482"
              },
              {
                name: "Ages",
                value: "10-20"
              }
            ]
          },

            ]
          },

              ShippingProfileID: `82379234987`,
              ShippingProfileName: `myShipping`
            },
            SellerReturnProfile: {
              ReturnProfileID: `82379234988`,
              ReturnProfileName: `myReturns`
            },
            SellerPaymentProfile: {
              PaymentProfileID: `82379234989`,
              PaymentProfileName: `myPayments`
            },
          },
        }
      }

      let result = await eBay.trading.AddFixedPriceItem(post) // attempts to post, expected to throw error
    
      console.log(`result: `, result)

    } catch(e) { // due to error, this catch is now triggered...
      console.log(e)
      console.log(`Attempting to refresh token...`);
      
      try {
        let newToken = await eBay.OAuth2.refreshToken()  // Isn't this correct?
        console.log(`newToken: `, newToken) 
        res.json(newToken)

      } catch(error){
        console.log(error)
      }

    }

}

Here is the relevant output I'm getting (I excluded the expected failed initial warning where ebay rejects the listing):

Attempting to refresh token...
TypeError: Cannot read property 'refreshToken' of undefined

What am I doing wrong? I am trying to list items to multiple accounts and each call requires user access token.
