Lua Requires Chilkat v9.5.0.85+

Refresh Wish for Merchants OAuth2 Access Token

See more OAuth2 Examples

Demonstrates how to refresh a Wish OAuth2 access token. Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- See Get Wish OAuth2 Access Token
-- for sample code showing how to obtain a Wish access token for desktop apps.

-- This example assumes we previously obtained an OAuth2 access token for Wish.

local jsonToken = chilkat.JsonObject.new()
local success = jsonToken:load_file("qa_data/tokens/wish.json")
if not success then
    print("Failed to load wish.json")
    return
end

-- The access token JSON looks something like this:

-- {

-- Note: In most OAuth2 implementations, the token endpoint is the same for both the
-- refresh request and the exchange-code-for-token request (which happens when getting
-- the OAuth2 token for the 1st time).   Wish uses a different URL for the refresh:
oauth2.token_endpoint = "https://merchant.wish.com/api/v3/oauth/refresh_token"
