# Create Signature Template

`POST /signatures/templates`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/signatures/templates`
- Auth: HTTP bearer

Create a signature template.

The block list is validated the way the in-app editor validates it: exactly
one required, locked identity block, at most one optional banner slot, unique
block ids. A rejected template answers 422 with the reason.

## Headers

    - `layout` 'classic-stacked' | 'photo-left' | 'logo-left' | 'two-column' | 'compact-inline' | 'banner-hero'
    - `blocks` Block[], required

      - `kind` 'identity' | 'contact' | 'photo' | 'logo' | 'social' | 'cta' | 'banner' | 'divider' | 'disclaimer' | 'green_footer' | 'custom_html', required

## Response `201`

Successful Response

- ApiResponseSignatureTemplateResponse
  - `data` SignatureTemplateResponse, required
    - `id` string, required
    - `version` integer, required
    - `data` object, required: The stored template document.
  - `pagination` PaginationMeta
    - `page` integer, required: Current page number (1-indexed)
    - `limit` integer, required: Items per page
    - `total` integer, required: Total number of items
    - `has_next` boolean, required: Whether there are more pages
    - `next_cursor` string, nullable: Opaque cursor for the next page; null when there are no more items. Pass it back as the `cursor` query param to fetch the following page without computing page numbers.
    - `total_available` integer, nullable: Search endpoints only: how many records really match, when known. Can be larger than `total`, which is capped at the 10,000 results that can be paged. For company search this is a distinct-company estimate. Null when unknown; absent outside search.
    - `total_is_lower_bound` boolean, nullable: Search endpoints only: true when more records match than `total` shows (the result set is larger than the 10,000 results that can be paged). Absent outside search.
    - `notes` string[], nullable: Search endpoints only: plain-language notes about the result, e.g. that more records match than can be paged, or that a reversed `between` range was put in order.
