Delete a template

Deletes a saved campaign template. Campaigns already created from it are unaffected - a campaign copies the template's steps at creation and keeps no link to it. Rate limit: this endpoint has a tighter cap of 20 requests/minute and 500/day, applied inside the shared campaigns bucket of 30 requests/minute and 1,000/day per token owner (shared by every campaign, scheduled-send, campaign-template and knowledge-hub endpoint).

Errors:

• 404 TEMPLATE_NOT_FOUND — No template with this id exists, or it is not visible to you.
• 422 VALIDATION_FAILED — campaignTemplateId is not a 24-character hex id.
• 429 RATE_LIMITED — Either this endpoint's own cap (20 requests/minute, 500/day) or the shared campaigns bucket (30/minute, 1,000/day for this token owner, shared by every /business/campaigns, /business/scheduled-sends, /business/campaign-templates and /business/knowledge-hubs call) was exceeded. The RateLimit-* headers on the response describe the shared bucket, so a refusal from this endpoint's own cap can still report requests remaining and carries no Retry-After.
• 500 UNEXPECTED_ERROR — An unhandled failure; the detail stays in our logs and is never returned.

Requires one of the following token scopes: campaigns.
