udayar_jayam Initial connection between salesforce to external system
Hi All,
For the first time i am doing integration. Im having a consumer key and secret key of external system.Now I want to do initial connection between salesforce to external system using REST API, how to acheive this. Kindly give me any links and sample programs. I have seen the rest api documentation but i dont get any idea. Thanks in advance
1) Upon loading the page, redirect to the external service's OAuth endpoint, with a redirect_uri set to the Visualforce page that will handle the response (can be the same page).
2) User logs in to the external system via some means.
3) When your page is reloaded, it will have the "code" parameter, which is an authorization code to get an access_token and possibly a refresh_token.
4) Your page calls the token endpoint to get a refresh token and/or access token. You can discard "code", but store refresh token and access token securely.
5) You are now connected to the external system and can use those tokens as you desire. Each attempt to access the external system will have to check and make sure the access token is still valid, and if not, refresh the token, and if that fails, inform the user that they need to reconnect.
