Using variables after Wait in workflow

Here is my use case:

  • Trigger a workflow
  • Send an request to external REST API endpoint
  • Retrieve a specific ID (as a part of body) back from the endpoint
  • Wait for 29 days
  • Send another API request in which use the ID received from previous request

My question is does the workflow support using the variable from previous action after 29 days

Is the API endpoint specific to an identity/account or something else? The reason for asking is thinking about using a delimited file source (never actually aggregated directly) where you could add/update/delete “accounts” as needed. It’s a HACK, but something we’ve used in other edge cases.

All APIs are external
