The campaign's send queue by status

Lists one bucket of the campaign's send queue. status=approval_required returns AI-drafted messages waiting for your decision through POST /business/scheduled-sends/approve or /decline; scheduled is the upcoming queue, each row due at scheduledAt (UTC); sent, skipped, stopped (declined - terminal for that contact) and overwritten (replaced by a newer row through PATCH /business/scheduled-sends/{sendId}) are history. body is the exact message that will go out, including the unsubscribe footer when the campaign appends one. Add channel to narrow to one channel, named exactly as a step's channel is. Only the token owner's own campaigns resolve: a campaign delegated to you, one shared by your team's visibility settings, and a deleted one all answer 404. 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 — status is missing or not one of the four buckets, channel is not one of the stored channels, or a paging value is out of range; param names the field.
• 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.
