# Change the sender name

`PATCH /email-providers/{providerId}/sender-name`

## Request

- Base URL: `https://api.emelia.io`
- URL: `https://api.emelia.io/email-providers/{providerId}/sender-name`
- Auth: API key in header `Authorization`

Updates only the sender name of a mailbox (any type), without retesting credentials. Note: Outlook always displays the name of the Microsoft account.

## Path parameters

- `providerId` string, required: MongoDB ObjectId: 24 hexadecimal characters.

## Request body

- object
  - `senderName` string, required

## Response `200`

Success.

- object
  - `success` unknown
  - `id` string: MongoDB ObjectId: 24 hexadecimal characters.

## Other responses

- `400`: Invalid request or business error (the API also uses 400 for "not found").
- `401`: Missing, malformed, unknown or disabled API key. The key must be exactly 48 characters, otherwise it is treated as a session token and rejected the same way.
- `500`: Unexpected error. IMPORTANT: this is also what you receive today when the per minute quota of your account is exceeded (the quota error is not mapped to 429 for API keys). No `Retry-After` header is sent. Wait until the next minute window before retrying.
