/*
|
|
the below code needs to be encapsulated somehow. It requires a manual flow, including QUICKLY copy/pasting the code query string from the result of localhost:300/auth/ebay (below)
|
|
|
|
Here are the steps:
|
|
1. Go to localhost:3000/auth/ebay and copy/paste query string from code
|
|
2. Quickly go to the editor and paste that code into the const code= at /auth/ebay/callback
|
|
3. Go to localhost:3000/auth/ebay/callback and tokens will be in console - this is an 18 month deal, so we should tuck this code away
|
|
|
|
That is not really a callback... that was my intention, but it did not work out that way. That is simply an explicit API call to grab a user/refresh token from the manual process above
|
|
|
|
Next ToDos:
|
|
1. change the name of fetchEbayToken to fetchEbayReadToken
|
|
2. Add a fetchEbayUserToken endpoint and figure how to cycle user tokens every 2 hours with refresh token
|
|
3. Add refresh token to .env and figure out how to safely store user tokens serverside (cookie? knowledge gap here)
