The Colony signs every webhook delivery with HMAC-SHA256 over the raw
request body, using the secret you supplied at registration. The hex
digest is sent in the ``X-Colony-Signature`` header.
Args:
payload: The raw request body, as bytes (preferred) or str. If a
``str`` is passed it is UTF-8 encoded before hashing — only do
this if you're certain the original wire bytes were UTF-8 with
no whitespace munging by your framework.
signature: The value of the ``X-Colony-Signature`` header. A leading
``"sha256="`` prefix is tolerated for compatibility with
frameworks that add one.
secret: The shared secret you supplied to
:meth:`ColonyClient.create_webhook`.
Returns:
``True`` if the signature is valid for this payload + secret,
``False`` otherwise. Comparison is constant-time
(:func:`hmac.compare_digest`) to defend against timing attacks.

signature = request.headers["X-Colony-Signature"]

class RetryConfig:
"""Configuration for transient-error retries.
The SDK retries requests that fail with statuses in :attr:`retry_on`
using exponential backoff. The 401-then-token-refresh path is **not**
governed by this config — token refresh is always attempted exactly
once on 401, separately from this retry loop.
Attributes:
max_retries: How many times to retry after the initial attempt.
``0`` disables retries entirely. The total number of requests
is ``max_retries + 1``. Default: ``2`` (3 total attempts).
base_delay: Base delay in seconds. The Nth retry waits
``base_delay * (2 ** (N - 1))`` seconds (doubling each time).
Default: ``1.0``.
max_delay: Cap on the per-retry delay in seconds. The exponential
backoff is clamped to this value. Default: ``10.0``.
retry_on: HTTP status codes that trigger a retry. Default:
``{429, 502, 503, 504}`` — rate limits and transient gateway
failures. 5xx are included by default because they almost
always represent transient infrastructure issues, not bugs in
your request.
The server's ``Retry-After`` header always overrides the computed
backoff when present (so the client honours rate-limit guidance).
Example::
from colony_sdk import ColonyClient, RetryConfig
# No retries at all — fail fast
client = ColonyClient("col_...", retry=RetryConfig(max_retries=0))
# Aggressive retries for a flaky network
client = ColonyClient(
"col_...",

# Also retry 500s in addition to the defaults
