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. Ruby

require 'chilkat'

success = false

# 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"
# }

json = Chilkat::CkJsonObject.new()
success = json.LoadFile("qa_data/tokens/ebay-access-token.json")
if (success == false)
    print "Failed to load the existing ebay access token JSON." + "\n";
    exit
end

oauth2 = Chilkat::CkOAuth2.new()

oauth2.put_TokenEndpoint("https://api.sandbox.ebay.com/identity/v1/oauth2/token")

# Replace these with actual values.
oauth2.put_ClientId("EBAY_CLIENT_ID")
oauth2.put_ClientSecret("EBAY_CLIENT_SECRET")

# Get the "refresh_token"
oauth2.put_RefreshToken(json.stringOf("refresh_token"))

# Send the HTTP POST to refresh the access token..
success = oauth2.RefreshAccessToken()
if (success == false)
    print oauth2.lastErrorText() + "\n";
    exit
end

# Load the access token response into the JSON object 
json.Load(oauth2.accessTokenResponse())

# 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.put_EmitCompact(false)
json.WriteFile("qa_data/tokens/ebay-access-token.json")

print "OAuth2 authorization granted!" + "\n";
print "New Access Token = " + oauth2.accessToken() + "\n";
