Tray offers hundreds of pre-built connectors and also offers a 'universal toolkit' to make any connection available via API request or webhook.
You may see marketing information that shows a connector is available via one of our universal connectors, like this example for Avalara below:
The 'Universal Connectors' are the (1) HTTP-client connector, (2) The GraphQL connector, and the (2) Generic webhook trigger.
These are connectors that allow you to connect to any REST, SOAP, or GraphQL API and receive webhooks from any service that can send POST requests to a URL. If you don't see a pre-built connector for a service, you can still make a connector using these tools.
