The Questrade API enables you to develop live or practice applications that can access your account data and retrieve market data. If you are a Questrade partner developer, you can also use the API to place trades.

Send authorized request to the Questrade API. Questrade only allows API requests via HTTPS (TLS) and refuses connections when accessed via HTTP. The required HTTP method (GET, POST etc.) must be defined. OAuth 2.0 uses an access token (a string credential) for security. You'll receive an access token and a refresh token at the same time.

Questrade uses a REST API, for access to read and write Questrade data and OAuth 2.0 as a security protocol. The Rest web service can be integrated into your custom solutions and allows for the delivery of your data in JSON format. Connect customers to applications on the Questrade trading platforms.

You are now ready to start making requests to Questrade’s IQ platform using your personal access token. While you are getting accustomed to Questrade's API, you can control API access by going to Security settings in the API centre and setting the General API access option to On or Off as per your preference.
