Authentication

Every authenticated request carries a bearer token:

Authorization: Bearer <your-token>

The same token authenticates the REST API, the MCP server and the CLI.

Create a token in Postlyra

1. Open app.postlyra.com and sign in.
2. Go to your profile, then the API tokens tab (/profile/api-tokens).
3. Click Create token, give it a name you will recognise later, and confirm with your password.
4. Copy the token immediately.

The token is shown once. Postlyra stores a hash of it, not the token, so it genuinely cannot be shown again. If you lose it, revoke it and create another.

A token from here is full account access

There are no per-brand tokens: a token can read and write everything its owner can, across every brand on the account. Store it like a password, never commit it, and revoke it the moment a machine holding it is lost.

Tokens do not expire. The only way one stops working is if you revoke it on that page, or POST /auth/logout with it.

A narrower token, for one brand's integrations

Studio, then Settings, then the API tab (owner only) mints a different kind of token: reaches every brand you belong to the same way, but limited to one access tier you pick at creation.

Tier	Can do
read	List and read posts, channels, media
standard_write	Everything above, plus create drafts and submit them for review
elevated_write	Everything above, plus approve: true when creating a post through Posts, audited in your name

A token's tier is fixed at mint time. Calling something above it is refused with 403 and a tier_denied code. This is the same tier system an MCP connection's consent screen uses, so the two stay consistent.

Get a token from the CLI

postlyra login gets its own token without any of this: it opens this page's flow in your browser, you approve once, and the token lands in the CLI's config. See the CLI.

Get a token programmatically

A client with no browser at all can trade credentials for a token directly, the same call postlyra login --with-password makes.

curl -X POST https://api.postlyra.com/auth/login \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -d '{"email":"ada@example.com","password":"..."}'

{
  "user": { "id": 1, "email": "ada@example.com" },
  "teams": [{ "id": 1, "name": "My Brand", "slug": "0f8fad5b-..." }],
  "current_team": { "id": 1 },
  "token": "1|AbCdEf..."
}

With two-factor enabled

The login response is a challenge instead of a token:

{ "two_factor_required": true, "two_factor_token": "9f2c..." }

Exchange it within 300 seconds:

curl -X POST https://api.postlyra.com/auth/two-factor-challenge \
  -H "Content-Type: application/json" \
  -d '{"two_factor_token":"9f2c...","code":"123456"}'

Send recovery_code instead of code to use a recovery code.

Both endpoints are throttled to 10 requests per minute.

Revoking

How	Effect
Profile, then API tokens, then Revoke	Deletes that one token
POST /auth/logout	Deletes only the token used to make that call
Deleting your account	Deletes every token on it

You cannot revoke the token you are currently signed in with from the token page. Do it from another session.

Passkeys

Passkey login is available for the app. It is a WebAuthn ceremony over POST /auth/passkeys/login/options then POST /auth/passkeys/login, and it returns the same payload as password login. It needs a browser to perform the ceremony, so it is not a practical way to authenticate a script. Use a token from the profile page instead.
