GetCampaignSequence

## Retrieves the current sequence (workflow) of a campaign as a PublicSequenceNodeDto. The returned object is directly compatible with the `sequence` field in **Create** and **UpdateSequence** - you can use it as-is without modification. Returns an empty 200 response if the campaign has no sequence. ### Query Parameters - **campaignId** _(long, required)_: The campaign whose sequence to retrieve. ### Integration node payloads in the response `SEND_LEAD_TO_*` payloads include the current state of the external lead flag (see **UpdateSequence** for the full schemas): - `SEND_LEAD_TO_SMARTLEAD`: `pauseExternalLead` is always present. - `SEND_LEAD_TO_INSTANTLY`: `removeExternalLead` is present only when `resourceType` is `CAMPAIGN`; it is omitted entirely for `LIST`. - `SEND_LEAD_TO_BISON`: `stopExternalLead` is `null` when the node has no `bisonCampaignId`. If you edit a response before sending it back, keep those rules in mind - adding `removeExternalLead` to a `LIST` node, or `stopExternalLead` to a node without a `bisonCampaignId`, is rejected with 400.
