# Delete an SMS suppression

`DELETE /v1/sms/suppressions/{suppression_id}`

## Request

- Base URL: `https://us1.platform.bird.com`
- URL: `https://us1.platform.bird.com/v1/sms/suppressions/{suppression_id}`
- Auth: one of:
  - HTTP bearer
  - API key in cookie `bird_session`

Ends a suppression, so the sender reaches the subscriber again. The record stays with the ending noted on it. This history helps answer later complaints or carrier audits.

**Only the `manual` reason can be ended here.** A `keyword_stop` is the subscriber's own statement. It ends only when they text a start keyword to that sender. A `carrier_opted_out` mirrors what the carrier reported, so it ends when the carrier says so. Attempts to end either reason return `422`.

Ending a suppression resumes messaging to someone your own records say did not want it, so do it only when you know why the `manual` record exists. An ID that does not exist in the workspace returns `404`, and one that has already ended returns `204`.

## Headers

- `Idempotency-Key` string
- `X-Workspace-Id` string
- `X-Organization-Id` string

## Response `204`

Suppression ended.

## Other responses

- `400`: Bad request
- `401`: Authentication required
- `403`: Insufficient permissions
- `404`: Resource not found
- `422`: The request has invalid field values, violates a business rule, or carries a query parameter the endpoint does not declare. Field validation errors use `type: validation_error` and include the affected fields in `details`. Business-rule errors identify the failed rule in `type`.
- `429`: Rate limit exceeded
- `500`: Internal server error
- `503`: The service is temporarily unavailable. If `Retry-After` is present, wait for that delay before retrying; otherwise, retry with exponential backoff. Reuse the same idempotency key and request when retrying a mutation.
