The first time you attempt to connect TRYTN to another app within Zapier you will need to authenticate with TRYTN. You will be presented with a screen that looks similar to this:
On this screen select "Sign in to TRYTN" and another screen will be presented asking for some additional information.
For Zapier you are required to provide your Business ID as well as your Secret Key. Both pieces of information can be found under Settings > API Keys. If you do not see a Business ID or Secret Key you need to select + Add. Once you create an API key you will have access to these pieces of data.
When successful you will be presented a screen similar to the following. You can now continue with your integrations.
