Remove a sequence step

Removes one sequence step. The remaining steps are renumbered so sequenceNumber stays contiguous from 0, which is the only operation that shifts existing steps. Queued sends already created for the removed step are not retro-actively deleted. Only the token owner may delete steps. 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.
• 404 SEQUENCE_STEP_NOT_FOUND — No step with this id belongs to this campaign.
• 422 VALIDATION_FAILED — campaignId or stepId 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.
