ETrade OAuth1 Authorization (3-legged) Step 1

See more ETrade Examples

Demonstrates the first step in 3-legged OAuth1 authorization for the ETrade REST API. This example sends an HTTP request to the "request token URL" to get a request token that begins the OAuth1 process. (See https://apisb.etrade.com/docs/api/authorization/request_token.html )

This example uses the sandbox request token URL. The live request token URL would be "https://api.etrade.com/oauth/request_token".

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

# Note: This example uses the sandbox request token URL.
# The live Get Request Token Request URL is:
# https://api.etrade.com/oauth/request_token
# This example will use the Sandbox Token Request URL:
requestTokenUrl = "https://apisb.etrade.com/oauth/request_token"

# If successful, the resp.BodyStr contains something like this:

# The next step is to form a URL to send to the authorizeUrl
# This is an HTTP GET that we load into a popup browser.

# Launch the system's default browser navigated to the URL.
oauth2 = chilkat.CkOAuth2()
success = oauth2.LaunchBrowser(url)
if (success == False):
    print(oauth2.lastErrorText())
    sys.exit()

# The ETrade account owner will login and grant access to the application.
# A short verifier code will be displayed (as shown below), and this must be copy-and-pasted
# into the next step to Complete the 3-legged OAuth1 Authorization 

# Note: The browser will NOT automatically direct you to the next page.
# You should copy the verifier code, close the browser, and then paste the verifier
# code into your application.
