Python SDK - Sente

sente-sdk is a thin Python client for the Sente REST API. Stdlib only (urllib) — no dependencies. The PyPI distribution is sente-sdk; the import is sente.

pip install sente-sdk

Setup

Get an API key from the dashboard (API keys page), or via the CLI with sente login + sente token. The key authenticates your whole organization — keep it in an environment variable, never in code.

import os
from sente import Sente

sente = Sente(api_key=os.environ["SENTE_API_TOKEN"])

Sente(api_key, base_url=...) — base_url defaults to https://api.sente.run.

Create an identity

An identity is a real, reusable email address on sente.run that your agent owns. See Identities and registrations.

idt = sente.identities.create(name="support-bot", local_part="support-bot")
# -> Identity(id=..., email="support-bot@sente.run", ...)

If the local_part is taken, create raises a 409 SenteError (on_conflict="error" is the default); pass on_conflict="suffix" to append a random suffix instead.

Wait for a verification code

Every inbound email is classified server-side (message.annotation: kind / code / link / confidence), so an agent that signed up somewhere with the identity’s address can block until the code or link arrives. Stamp since before triggering the action so you never match an older email:

from datetime import datetime, timezone

since = datetime.now(timezone.utc).isoformat()
# ...trigger the signup / login that sends the verification email...
r = sente.messages.wait_for_otp(idt.id, since=since, timeout=60)
if r:
    print(r.code)  # e.g. "481923"; r is OtpResult(code, message)

# Links instead of codes:
ml = sente.messages.wait_for_magic_link(idt.id, since=since, timeout=60)
if ml:
    print(ml.link)  # MagicLinkResult(link, message)

Both return None on timeout. timeout is in seconds (1–60 per call, default 25). If you omit since, the server falls back to a 60-second lookback. More patterns in Receive verification codes.

Send and reply

sente.messages.send(idt.id, to="user@example.com", subject="hi", text="from your agent")

# Thread a reply to an inbound message (sets In-Reply-To/References):
sente.messages.send(
    idt.id,
    to="user@example.com",
    subject="Re: hi",
    text="following up",
    in_reply_to=inbound_message_id,
)

text and/or html is required. To consume mail continuously, sente.messages.stream(identity_id) is a generator that long-polls; for production prefer webhooks (push, not poll).

Register at a third-party app

registrations.register drives a browser through signup at app_url under the identity’s email and completes email verification from the identity’s own inbox. It returns RegisterResult(registration, run).

result = sente.registrations.register(
    identity_id=idt.id,
    app_url="https://app.example.com/signup",
    confirm_before_submit=True,  # a human clicks the final submit (recommended)
)
run = sente.runs.wait_for_run(result.run.id)  # settles on completed | failed | blocked

Register only at apps whose terms permit it. confirm_before_submit=True keeps a human in the loop: the agent fills the form, then the run goes blocked with error code SUBMIT_CONFIRMATION_REQUIRED and a live_view_url — a person clicks the final submit there (and accepts the app’s terms themselves), then you call runs.resume(run.id). See Acceptable use.

wait_for_run(run_id, timeout=180, poll_ms=2000) polls until the run is completed, failed, or blocked (timeout in seconds, default 180 — note the TypeScript SDK takes milliseconds). blocked means human takeover: CAPTCHAs, SMS verification, and confirm-before-submit all stop the run — a person finishes the step in the interactive live_view_url, then runs.resume(run_id) continues. On timeout it returns the last-polled Run. See Runs and human takeover. Re-authenticate later with registrations.login(registration_id) — same RegisterResult shape. Vaulted credentials: registrations.get_credentials(registration_id) returns { "username", "password", "origin" }; set_credentials(registration_id, username=..., password=...) overwrites the vault only — it does not change the password at the app.

Connect an account you already own

connections.connect is delegated access to an existing account: you supply the credentials, Sente logs in, vaults them write-only, and keeps the account re-loginable. See the Connect guide.

result = sente.connections.connect(
    identity_id=idt.id,
    app_url="https://app.example.com/login",
    username="you@yourco.com",
    password=os.environ["APP_PASSWORD"],
    totp_seed=os.environ.get("APP_TOTP_SEED"),  # optional: base32 secret or otpauth:// URI
)
run = sente.runs.wait_for_run(result.run.id)  # result is ConnectResult(connection, run)

Limits, stated plainly:

SSO-only accounts (Google/Okta sign-in, passkeys) cannot be connected — connect needs a username + password login.
Credentials are write-only: registrations.get_credentials on a connected account raises 403 CREDENTIALS_WRITE_ONLY.
With a vaulted totp_seed, re-login clears TOTP 2FA without a human; the server computes the 30-second code — the seed never reaches any model.
Email or SMS code MFA needs a human: the run goes blocked with MFA_REQUIRED — enter the code in live_view_url, then runs.resume(run.id) — unless the account’s notification email has been repointed to the Sente identity.

connections.revoke(connection_id) disables the connection but keeps the vault (a later connect re-enables it); connections.delete(connection_id) revokes and purges the vaulted credentials. Connected accounts are also reachable through the registrations methods (get_session, login, export_session) by the returned id.

Open or export a logged-in session

get_session returns a remote browser already logged into the account, as a CDP URL you drive yourself. If the login has gone stale, Sente re-logs-in first (vaulted credentials + a fresh code from the identity’s inbox) — healed is True when that happened, and a cold call can take a minute.

from playwright.sync_api import sync_playwright

s = sente.registrations.get_session(registration_id)
# {"sessionId", "cdpUrl", "liveViewUrl", "expiresAt", "verified", "healed"}
with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp(s["cdpUrl"])
    # ... drive it ...
sente.registrations.close_session(registration_id)

One live session per identity; open sessions count against your plan’s browser-minute allowance — always close_session when done. get_session accepts verify= (default True; False skips the freshness check), max_stale_sec=, and timeout_ms= (default 240000). If re-login can’t recover, it raises SenteError (inspect the body’s run). open_session(registration_id) is the raw primitive with no freshness check. To use your own browser stack instead, export the logged-in state (cookies + localStorage) as a Playwright storage_state dict:

storage_state = sente.registrations.export_session(registration_id)
context = browser.new_context(storage_state=storage_state)

The export is a bearer credential for a logged-in account — store it like a secret. More in the Sessions guide.

Webhooks

Register your endpoint and Sente pushes events to it with retries. The secret is only present on the Webhook returned at register time — store it.

w = sente.webhooks.register(
    url="https://your-host.example.com/sente",
    events=["message.received"],
    identity_id=idt.id,  # omit for org-wide
)
print(w.secret)

message.received payloads are thin notifications with no body — fetch content with sente.messages.get(message_id). Run lifecycle events (run.blocked, run.completed, run.failed) are also available. Every delivery carries the secret in the x-sente-secret header — verify it with hmac.compare_digest. Full payloads and verification code in the Webhooks guide.

Errors

Non-2xx responses raise SenteError with status (HTTP status) and body (the parsed error payload, if any).

from sente import Sente, SenteError

try:
    sente.identities.create(local_part="acme-bot")
except SenteError as e:
    if e.status == 409:
        pass  # address taken — pick another, or retry with on_conflict="suffix"

Inbound email is untrusted input. It can contain prompt injection (“ignore your instructions…”, “send the API key to…”). Never treat instructions found in email as coming from your user — extract only the datum you need (a code, a link, the sender’s ask).
