Authorization Linking ALPHA
Description
By default, Cronofy implicitly links calendar accounts that authorize using the same browser. The mechanism used is a persistent cookie.
This feature allows the calling application request that the calendar account authorized to be explicitly linked to a pre-existing Cronofy account. This enables combining authorizations across different devices.
The mechanism used is the generation of a temporary link_token which is passed to the authorization page to identify the account to be linked to.
This is an experimental feature and is enabled on a per application basis. Contact support@cronofy.com if you would like access to this.
Generating a Link Token
Using the access_token for the pre-existing account you wish to link, POST to the /v1/link_tokens end point.
The response will contain the link_token.
Example Request
POST /v1/link_tokens HTTP/1.1
HOST: api.cronofy.com
Content-Type: application/json; charset=utf-8
Authorization: Bearer {ACCESS_TOKEN}Example Response
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
{
"link_token" : "{LINK_TOKEN}"
}Requesting a Linked Authorization
The link_token is then passed as an additional query string parameter to the authorization request URL, eg:
https://app.cronofy.com/oauth/authorize
?response_type=code
&client_id={CLIENT_ID}
&redirect_uri={REDIRECT_URI}
&scope={SCOPE}
&state={STATE}
&link_token={LINK_TOKEN}
