PostEverywhere Python SDK

The official Python client for the PostEverywhere API.

Schedule and publish posts to Instagram, TikTok, YouTube, LinkedIn, Facebook, X, Threads, Pinterest, Bluesky, Telegram, Discord and WordPress from Python. The library has one dependency (httpx), ships type hints, and has a sync and an async client.

Install

pip install posteverywhere

Python 3.9 or newer.

Get an API key

Create a key at app.posteverywhere.ai/developers. Keys start with pe_live_. Set it as an environment variable:

export POSTEVERYWHERE_API_KEY="pe_live_..."

The client reads POSTEVERYWHERE_API_KEY when you do not pass api_key.

Quick start

from posteverywhere import PostEverywhere

client = PostEverywhere()  # or PostEverywhere(api_key="pe_live_...")

# 1. Find the accounts to post to. Account IDs are integers.
accounts = client.accounts.list()["accounts"]
for account in accounts:
    print(account["id"], account["platform"], account["account_name"])

# 2. Schedule a post. Omit scheduled_for to publish now.
post = client.posts.create(
    content="Our spring update is live.",
    account_ids=[accounts[0]["id"]],
    scheduled_for="2026-10-01T14:30:00Z",
    timezone="America/New_York",  # display only, never changes when it fires
)
print(post["post_id"], post["post_status"])

# 3. Check the result for each platform.
results = client.posts.results(post["post_id"])
for r in results["results"]:
    print(r["platform"], r["status"], r.get("platform_post_url"))

scheduled_for accepts an ISO 8601 string or a datetime. A value with no offset is treated as UTC.

Every method returns the data object from the API response as a plain dict. Field names match the API reference exactly.

More examples

# Attach an image from a public URL
media = client.media.upload_from_url("https://example.com/launch.png")
client.posts.create(content="Launch day", account_ids=[2280], media_ids=[media["media_id"]])

# Different text per platform
client.posts.create(
    content="Default caption",
    account_ids=[2280, 2291],
    platform_content={"x": {"content": "Shorter caption for X"}},
)

# Save a draft, then schedule it later
draft = client.posts.create(content="Draft for review", account_ids=[2280], draft=True)
client.posts.schedule(draft["post_id"], publish_now=True)

# Filter posts
failed = client.posts.list(status="failed", platform=["instagram", "tiktok"], limit=50)

# Retry failed destinations
client.posts.retry(post["post_id"])                # one post
client.posts.retry_failed(platform="tiktok")      # everything that matches a filter

# Create up to 50 posts in one call
batch = client.posts.bulk_create([
    {"content": "Post one", "account_ids": [2280]},
    {"content": "Post two", "account_ids": [2280], "scheduled_for": "2026-10-02T09:00:00Z"},
])
print(batch["summary"])  # {"total": 2, "succeeded": ..., "failed": ...}

# Check an account before you post
health = client.accounts.health(2280)
if not health["can_post"]:
    print("Reconnect needed:", health["status"])

# AI captions (uses AI credits)
captions = client.ai.generate_caption("Summer sale, 30% off", platform="instagram", count=2)

# Analytics, campaigns, rules, and key info
client.analytics.summary(period="week")
client.campaigns.create("Q4 Launch", color="#3b82f6")
client.platform_rules()
client.me()

Async

AsyncPostEverywhere has the same methods. Each one returns a coroutine.

import asyncio
from posteverywhere import AsyncPostEverywhere

async def main():
    async with AsyncPostEverywhere() as client:
        accounts = await client.accounts.list()
        post = await client.posts.create(
            content="Hello from asyncio",
            account_ids=[a["id"] for a in accounts["accounts"]],
        )
        print(await client.posts.results(post["post_id"]))

asyncio.run(main())

Errors

Failed requests raise a subclass of PostEverywhereError. Each error has status, code, message, request_id and details.

Exception	When
ValidationError	400 or 422, the request was rejected
AuthenticationError	401, the key is missing, invalid, revoked or expired
PaymentRequiredError	402, no active subscription or not enough AI credits
PermissionDeniedError	403, the key lacks the scope, or a quota blocks the call
NotFoundError	404
ConflictError	409, for example scheduling a post that is not a draft
RateLimitError	429, has retry_after in seconds
APIError	5xx or any other unexpected status
APIConnectionError	network error or timeout, no response

from posteverywhere import PostEverywhere, RateLimitError, ValidationError

client = PostEverywhere()
try:
    client.posts.create(content="Hi", account_ids=[2280], scheduled_for="2020-01-01T00:00:00Z")
except ValidationError as e:
    print(e.code, e.message)  # past_schedule_time ...
except RateLimitError as e:
    print("Try again in", e.retry_after, "seconds")

Include request_id when you contact support.

Retries and timeouts

The client retries up to max_retries times (default 2):

• 429 responses, after the Retry-After delay.
• 5xx responses on GET and DELETE requests, with exponential backoff.
• Connection errors.

It does not retry a 5xx on POST or PATCH. The server may have done the work, and a retry could publish a post twice. Check with posts.list or posts.get first.

client = PostEverywhere(timeout=30.0, max_retries=5)

The default timeout is 120 seconds, because AI generation can be slow.

Webhooks

Each webhook delivery has an X-PostEverywhere-Signature header. It is sha256= plus the HMAC-SHA256 of the raw body, keyed with the secret you got when you created the webhook. Verify it before you trust the payload:

from posteverywhere import verify_webhook_signature

# Flask example
@app.post("/hooks/posteverywhere")
def hook():
    ok = verify_webhook_signature(
        request.get_data(),  # the RAW body, not re-encoded JSON
        request.headers.get("X-PostEverywhere-Signature"),
        WEBHOOK_SECRET,
        timestamp=request.headers.get("X-PostEverywhere-Timestamp"),  # rejects deliveries older than 5 minutes
    )
    if not ok:
        return "invalid signature", 401
    event = request.get_json()
    print(event["event"], event["data"])
    return "", 200

Create a webhook and send a test event:

hook = client.webhooks.create(
    "https://example.com/hooks/posteverywhere",
    events=["post.published", "post.failed"],
)
print(hook["secret"])  # shown only once: save it now
client.webhooks.test(hook["id"])
