Refresh eBay Application Access Token

See more eBay Examples

This example shows how to get a new eBay REST API access token when the original is close to expiration. Lua

local chilkat = require("chilkat")

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

-- The previously fetched eBay access token looks like this:

-- {
--   "access_token": "v^1.1#i^1# ... HwSAAA=",
--   "expires_in": 7200,
--   "refresh_token": "v^1.1#i^1# ... FXjEyODQ=",
--   "refresh_token_expires_in": 47304000,
--   "token_type": "User Access Token"
-- }

local json = chilkat.JsonObject.new()
local success = json:load_file("qa_data/tokens/ebay-access-token.json")
if not success then
    print("Failed to load the existing ebay access token JSON.")
    return
end

local oauth2 = chilkat.OAuth2.new()

oauth2.token_endpoint = "https://api.sandbox.ebay.com/identity/v1/oauth2/token"

-- Replace these with actual values.
oauth2.client_id = "EBAY_CLIENT_ID"
oauth2.client_secret = "EBAY_CLIENT_SECRET"

-- Get the "refresh_token"
oauth2.refresh_token = json:string_of("refresh_token")

-- Send the HTTP POST to refresh the access token..
success = oauth2:refresh_access_token()
if not success then
    print(oauth2.last_error_text)
    return
end

-- Load the access token response into the JSON object
json:load(oauth2.access_token_response)

-- Save the new JSON access token response to a file.
-- The access + refresh tokens contained in this JSON will be needed for the next refresh.
json.emit_compact = false
json:write_file("qa_data/tokens/ebay-access-token.json")

print("OAuth2 authorization granted!")
print("New Access Token = " .. oauth2.access_token)
