List a campaign's sequence steps

Lists the campaign's sequence steps in sequenceNumber order (0-based). A campaign created through this API starts with one empty step per requested channel, so this is how you discover the ids to write content into with PATCH /business/campaigns/{campaignId}/steps/{stepId}. type tells you what to write: manual needs subject and body, ai_generated and ai_reply write from topic. Only the token owner's own campaigns resolve here. Rate limit: 30 requests/minute and 1,000/day per token owner, shared by every campaign, scheduled-send, campaign-template and knowledge-hub endpoint.

Errors:

• 404 CAMPAIGN_NOT_FOUND — No campaign with this id exists, it belongs to another account (including a campaign delegated to you or shared by your team's visibility settings), or it has been deleted.
• 422 VALIDATION_FAILED — campaignId is not a 24-character hex id.
• 429 RATE_LIMITED — More than 30 campaign requests in a minute, or 1,000 in a day, for this token owner (the bucket is shared by every /business/campaigns, /business/scheduled-sends, /business/campaign-templates and /business/knowledge-hubs call).
• 500 UNEXPECTED_ERROR — An unhandled failure; the detail stays in our logs and is never returned.

Requires one of the following token scopes: campaigns.
