The template is a snapshot; later edits to the campaign do not change it, and editing the template is not exposed here. Use the returned id as `templateId` when creating a campaign. Only the token owner's own campaigns can be snapshotted: 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` — `name` or `campaignId` is missing, unknown key, or campaignId is not a 24-character hex id; `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. ## OpenAPI ````yaml /openapi.json post /business/campaign-templates openapi: 3.1.0 info: title: Fuse Business API version: 1.0.0 description: >- External API for lists, campaigns, prospect search and contacts.
