How do I activate an integration?

All integrations can be activated from your account integrations page. In most cases, the integration requires only one click in order to be activated.

Client-side Integrations

Many of the Appcues integrations are client-side integrations, which means they talk to the third-party through the user's browser in order to send information about Appcues activity to the destination. You'll need to have the third-party's javascript installed in your app for this to work.     
Note that if a client-side integration is a two-way integration data from the destination to Appcues may be server-side.

Fun fact: what's happening behind the scenes, and how is it only one click? Well, if you have the third-party javascript on your app, Appcues just needs to know that, and then route events to it in the browser, just like your app would for your standard analytics or user data. All that's happening when you activate the integration is flipping a switch that tells Appcues to look for that provider on the same page and tell it what's happening with your Appcues flows.

Server-side Integrations     

Other integrations are server-side integrations and work by directly communicating behind the scenes, or server-side—and may require some information, like an account ID or Legacy API key (called the API Key for legacy plan customers), in addition to a short authentication process.
