rmyndharis-openwa

Official Python SDK for the OpenWA WhatsApp API Gateway.

A synchronous client built on httpx, with bundled type hints (PEP 561).

Install

pip install rmyndharis-openwa

Requires Python 3.9+. The importable module is openwa.

Usage

from openwa import OpenWAClient

client = OpenWAClient(
    base_url="https://your-gateway.example.com",
    api_key="owa_k1_…",
)

client.sessions.start("my-session")

result = client.messages.send_text("my-session", {
    "chatId": "628123456789@c.us",
    "text": "Hello from the OpenWA Python SDK!",
})
print(result["messageId"])

The client is also a context manager (it closes the underlying connection pool on exit):

with OpenWAClient(base_url="…", api_key="…") as client:
    client.messages.send_text("my-session", {"chatId": "…@c.us", "text": "hi"})

For tests, pass an httpx transport — no global monkey-patching required:

import httpx
client = OpenWAClient(base_url="…", api_key="…", transport=httpx.MockTransport(handler))

Search

GET /search is wrapped as client.search.search(params). Only q is required; the rest (sessionId, chatId, direction, type, from, dateFrom, dateTo, limit, offset) are optional. dateFrom / dateTo are epoch-ms. The active search provider (built-in DB full-text, or a plugin) answers; if none is configured the server returns 501.

res = client.search.search({"q": "invoice", "sessionId": "my-session", "limit": 20})
for hit in res["hits"]:
    print(hit["snippet"], hit["score"])

Messaging

Voice notes: pass ptt=True inside the body dict to send_audio to send a real WhatsApp voice note (PTT). Supply audio/ogg; codecs=opus audio for reliable playback; the server defaults the mimetype to that when ptt is set without one.

Errors

A non-2xx response raises a typed OpenWAApiError subclass — OpenWAAuthError (401), OpenWAForbiddenError (403), OpenWANotFoundError (404), OpenWAConflictError (409), OpenWARateLimitError (429), OpenWANotImplementedError (501), OpenWAServiceUnavailableError (503 — the only retryable one) — each carrying .status and the parsed .body. A timeout raises OpenWATimeoutError.

from openwa import OpenWANotFoundError

try:
    client.sessions.get("missing")
except OpenWANotFoundError as e:
    print(e.status)  # 404

Notes

• Use HTTPS in production — the API key is sent as X-API-Key and is bearer-equivalent.
• The SDK does not retry, and never follows redirects (so the key is never re-sent to a redirect target). Path segments are percent-encoded; a base-URL path prefix (e.g. behind a reverse proxy) is preserved.
• Escape hatch for endpoints the SDK does not wrap: client.request(method, path, query=…, body=…).

Releasing

Publishing to PyPI is done by the python-sdk-release.yml workflow, which authenticates with PyPI Trusted Publishing (OIDC). There is no PyPI token in the workflow or in the repository secrets: PyPI mints a short-lived credential from the GitHub OIDC token, so nothing long-lived exists to leak or rotate.

One-time setup, required before the first tag — on pypi.org, open the project's publishing settings and add a GitHub trusted publisher:

• Owner: rmyndharis
• Repository: OpenWA
• Workflow name: python-sdk-release.yml

There are no repository secrets to add. Until the trusted publisher exists PyPI rejects the upload, so configure it first.

Cutting a release:

1. Bump version in pyproject.toml and land it on main.
2. Tag that commit py-sdk-v<version> (e.g. py-sdk-v0.5.0) and push the tag. The SDK has its own version line — the monorepo's v* tags are the app version and never trigger an SDK publish.
3. The workflow re-runs the test suite, builds the sdist and wheel, and uploads. The artifacts published are the ones those tests passed against.
