(Go) ETrade OAuth1 Authorization (3-legged) Step 1Demonstrates 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". Note: This example requires Chilkat v11.0.0 or greater.
