spec_type: none
spec_note: >-
Fixflo publishes NO AsyncAPI document. It does publish a real, documented
webhook surface with a managed subscription API, HMAC request signing and a
documented retry policy — captured here verbatim from the developer portal
Webhooks article and the v2 OpenAPI. Nothing below is inferred.
delivery:
transport: HTTPS POST
source_host: webhook.fixflo.com
source_host_note: >-
Verbatim — "Webhooks from Fixflo will be sourced from an IP address defined
by the CNAME webhook.fixflo.com" (for firewall allow-listing).
tls: recommended
tls_note: >-
Verbatim — "You may use an HTTP or a HTTPS url. However to help protect
against man-in-the-middle issues ... it is strongly advised that you use
HTTPS."
envelope:
format: json
fields:
- name: action
description: The type of event that occurred and triggered the webhook.
- name: payload
description: Further information about the event; for Issue state change this is an Issue object.
security:
signing:
algorithm: HMAC SHA256
header: ff-signature
value_format: sha256={hash}
encoding: hex string of the HMAC SHA256 of the raw request body
secret: per-webhook configured shared secret
verification_steps:
- Read the request body in its entirety.
- HMAC-SHA256 the body using the secret configured for the webhook.
- Hex-encode the digest and compare with the ff-signature value.
docs: https://api-docs.fixflo.com/5cc9374300b99-webhooks
reliability:
retries: true
max_attempts: 6
retry_window: approximately 10 minutes
retry_triggers:
- connection to the configured server cannot be made
- the hooked server responds with an HTTP 5xx error code
consumer_guidance: >-
Verbatim — "Due to the possibility of retries it is recommended that any
logic carried out on the server is idempotent or put another way, is still
valid even though the same message may be received more than once."

available: true
surfaces:
- Fixflo webhook configuration page (request + response log)
- GET /Webhook/Activity (paged, 20 per page, reverse chronological)

harvest.
