Start a workflow from any system, and call out to any system

Trigger a Riska workflow from anything that can send a signed HTTP request, and call any HTTP endpoint from a workflow step. If a system has an API, it can be part of your process.

## How it works

- **Connect what has no app yet**: Any system that can call a URL can start a workflow.
- **Signed requests**: Inbound requests are verified with a signature, so only your systems can trigger work.
- **Call out from a workflow**: Send an HTTP request from any step to update another system.

## Configure

1. **Add a webhook trigger** Create a workflow and choose the webhook trigger.
2. **Point your system at it** Send a signed request to the trigger URL.
3. **Call out** Add a Send HTTP request step wherever another system needs to hear about it.
