![](https://i.imgur.com/DxgjBlM.png) Authentication service - Technical documentation === > **Product Name:** SDK Web ShareID - Authenticate > **Version:** 1.0 > **Date:** 2022-12-22 # **Retrieve the result of an authentication** This is an addon on the current authentication flow. You may now use it also in this way to retrieve the result of an authentication. *You can use the session opening in this way:* ```json POST https://{sandbox}.shareid.net/authorization/v1/auth_business/login { "business_identifier": "my_business_identifier", "business_secret": "my_business_secret", "callback_url": "https://example.com/callback-response", "with_flow_id": true } ``` You will notice the last parameter ***with_flow_id*** which will tell the api to track the authentication. The service will reply the usual document, plus a new entry in the payload section containing the flow_id: ```json { "status": "success", "message": "Business logged in", "payload": { "access_token": "...", "expiresIn": 10, "flow_id": "de454b9f-4df8-4d47-b9c8-24578c3e199e" }, "trace": "..." } ``` You should keep this ***flow_id*** to be able to retrieve the result later. Once the authentication is over, you may call this new api: ```sh curl --location 'https://{sandbox}.shareid.net/v1/data/sdk/authentication_result/<FLOW_ID>' --header 'Authorization: Bearer <TOKEN>' ``` The ***<FLOW_ID>*** parameter must be replaced by the one you got from the session opening. The ***<TOKEN>*** parameter must be replaced by a valid token you have. This is also a token that you got from the session opening. *** ### Technical support and contact 💬 [Contact@shareid.ai](mailto:Contact@shareid.ai) * * *
