Create an amortization template for a non-native integration. Amortization does not have to be enabled first: if the integration has no amortization fields yet, creating a template provisions them. The first template also makes amortization selectable on expenses. Native ERP integrations are not eligible because their amortization data is owned by the ERP sync.

## Path parameters

- `integration_id` string, required

## Headers

- `Idempotency-Key` string

## Request body

- CreateAmortizationTemplateRequest
  - `name` string, required: Human-readable name of the template
  - `remote_id` string: The template's identifier in the ERP. Omit when the ERP has no id for it.

## Response `201`

Amortization template created

- AmortizationTemplate
  - `brex_id` string, required: The internal Brex ID of the amortization template
  - `is_disabled` boolean, required: Whether the template is hidden from selection on new expenses. Existing expenses keep a disabled template.
  - `name` string, required: Human-readable name of the template
  - `remote_id` string, nullable: The template's identifier in the ERP, if the ERP supplied one
  - `updated_at` string, date-time, required: The last updated timestamp of the template

## Other responses

- `400`: Bad request (e.g. blank name), or amortization could not be enabled for the integration
- `401`: The bearer token is missing or rejected.
- `403`: The token does not have a required scope.
- `404`: Accounting integration not found
