Forwarding agents let you set up your own integration with an external agent. Dart forwards the work to an endpoint you specify, and the external service's response comes back into the task or chat.
Setting up a forwarding agent
Go to Agents in the left navigation bar and select Create a custom agent.
Give the agent a Name and Icon.
Choose Forwarding as the type.
Define the endpoint to send data to, plus any headers and the request body template.
Choose the trigger that starts the agent — for example, when it's assigned, mentioned in a comment, or messaged in chat.
Map the response field that should be posted back as the agent's reply.
