How do I signal a workflow when my webhook doesn't contain the workflow id?

[jack932]

Hello I have a question maybe you can help me out by pointing me in the right direction.

1. A workflow (v1 engine) runs an activity that passes an email to an external API
2. (awaitWithTimeout)
3. Later, the external system calls my webhook with that email.
4. To signal the workflow I need its id (webhook only sends email, fixed payload).

What do you think should I do?

1. Store the workflow id together with the email in my own table
2. Add a searchable column to the workflows table via a custom StoredWorkflow model (workflows.stored_workflow_model config)

Or is there a built-in mechanism for this that I've missed?

Thank you and all the best

You are right. That is the best approach in v1.

1. start workflow
2. persist email -> workflow_id
3. webhook arrives with email
4. look up workflow id from your map
5. call WorkflowStub::load($workflowId)->someSignal(...)

In v2 there are search attributes that can be used for things like this.
