Can I delay my workflow until it receives a webhook from an eternal api?
To delay a workflow until it receives a webhook from an external API, you would typically use the webhook itself as the trigger for the workflow. This means the workflow would start its execution once the webhook is received. Pipedream workflows can be triggered by HTTP requests, including webhooks, which allows you to start the workflow execution based on the event you’re interested in. However, if you’re looking to pause or delay the workflow at a certain point after it has already started, until a specific condition is met (like receiving a webhook), you would need to implement a custom logic for that. Currently, Pipedream does not provide a built-in feature to pause a workflow’s execution waiting for an external webhook. Workflows are designed to execute sequentially from the trigger to the last action without waiting for external triggers to resume execution. For scenarios where you need to wait for an external event before proceeding, consider splitting your workflow into two parts: 1. The first part does the initial processing and ends by setting up a condition or storing data indicating that it’s waiting for the external webhook. 2. The second workflow starts with a webhook trigger, which is the webhook you’re waiting for. Once this webhook is received, the workflow can proceed with the actions that depend on this external event. This approach allows you to effectively “delay” the continuation of your process until the required webhook is received, by using two coordinated workflows.

can you give an overview of how $.flow.suspend() works?
Certainly! The $.flow.suspend() function in Pipedream is used to pause the execution of a workflow. This can be particularly useful in scenarios where you want to manually approve the continuation of the workflow or need to wait for an external event before proceeding. Here’s a brief overview of how it works: When you call $.flow.suspend() within a workflow step, Pipedream suspends the workflow at the end of that step. The suspension is essentially a pause, during which the workflow waits for a manual action to either resume or cancel the remaining steps. Here’s an example of how you might use $.flow.suspend(): export default defineComponent({ async run({ $ }) { const { resume_url, cancel_url } = $.flow.suspend() $.send.email({ subject: "Please approve this important workflow", text: `Click here to approve the workflow: ${resume_url}, and cancel here: ${cancel_url}`, }) // Pipedream suspends your workflow at the end of the step }, }) In this example, after calling $.flow.suspend(), an email is sent containing links to either resume or cancel the workflow. The workflow remains suspended until one of these actions is taken. It’s important to note that when you’re testing a workflow and you reach a step that includes $.flow.suspend(), the workflow will not actually be suspended. Instead, you’ll see a message indicating that the workflow execution was canceled due to the use of $.flow.suspend(), which is not supported in test mode. This behavior ensures smooth testing without interruptions but remember that the suspension functionality will work as expected when the workflow is run in production.

hopefully that helps point you in the right direction. This is implemented in a few of our public actions also: https://github.com/PipedreamHQ/pipedream/blob/6eaf0054e94d3e37fb873eab3241dd124ba4[…]mponents/deepgram/actions/transcribe-audio/transcribe-audio.mjs
