Why teams connect Adyen and Slack

Connect the financial records in Adyen with the work happening in Slack, so both stay current without exports or copy-paste.

Adyen holds the financial truth: who the customers are, what they were billed, what they paid. Slack is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.

Stacksync keeps Modifications (Captures, Refunds, Cancels), Payment Links, Merchant Accounts, Stores in Adyen and Channels, Messages, Threads, Users in Slack in sync, bi-directionally and in real time. Whatever records Slack keeps and whatever events it produces, the overlap with Adyen is mapped field by field, and a change on either side shows up on the other within seconds.

There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.

Common use cases

  • 01 Ingest AUTHORISATION, CAPTURE, REFUND, and CHARGEBACK webhooks into Postgres or a warehouse so finance reconciles Adyen settlements against orders in an ERP without manual report exports.
  • 02 Trigger a capture, refund, or cancel on an Adyen payment when an order's state changes in a CRM, OMS, or ERP, and write the returned pspReference and status back onto the record.
  • 03 Post CRM record changes into deal or account channels so the team sees updates without opening the CRM
  • 04 Sync the Slack user directory with the HRIS or identity provider to keep memberships and profiles current

Common sync patterns

Where Slack collects payments or triggers charges: events land in Adyen

Payment and charge activity flows into Adyen as it happens, so the books reflect reality without manual reconciliation.

Where Slack tracks people or companies: one identity

A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.

Where Slack is a docs or knowledge workspace: reference data kept fresh

Figures teams rely on, like customer status or outstanding balances, stay current wherever Slack surfaces them instead of going stale after a one-time paste.

What you can sync between Adyen and Slack

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Adyen objects Slack objects How this pairing syncs
Webhook Configurations Per-company or per-merchant webhook subscriptions (Management API); created, listed, and updated to control which events Adyen sends and to which endpoint and HMAC key. Files Uploads attached to messages, retrievable for archiving. Webhook Configurations is specific to Adyen and Files to Slack — each maps to any object or custom field on the other side.
Settlement Detail Reports Downloadable reports of settled transactions, fees, and payouts per merchant account; read-only, delivered when a report webhook fires, and loaded for finance reconciliation. Reactions Emoji responses that can drive workflows, such as approving a synced record. Settlement Detail Reports is specific to Adyen and Reactions to Slack — each maps to any object or custom field on the other side.
Payments Checkout API payment requests and results (/payments); created to authorize a card, wallet, or local payment, and retrieved by pspReference. Final state arrives asynchronously via the AUTHORISATION webhook. Channels Conversations (public, private, DMs) that messages are read from and posted to. Payments is specific to Adyen and Channels to Slack — each maps to any object or custom field on the other side.
Modifications (Captures, Refunds, Cancels) Actions on an authorized payment via /payments/{pspReference}/captures, /refunds, and /cancels; written to settle, return, or void funds, with results confirmed by CAPTURE and REFUND webhooks. Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Messages to Slack — each maps to any object or custom field on the other side.
Payment Links Hosted payment link objects created through /paymentLinks; created, retrieved, and expired, with paid or expired status reported back through webhooks for accounts-receivable sync. Threads Replies grouped under a parent message timestamp, preserved when archiving conversations. Payment Links is specific to Adyen and Threads to Slack — each maps to any object or custom field on the other side.
Merchant Accounts Company and merchant account entities in the Management API; read and updated to keep account configuration, payment-method settings, and capabilities aligned with internal systems. Users Workspace members with profile fields, synced against HR systems and identity providers. Merchant Accounts is specific to Adyen and Users to Slack — each maps to any object or custom field on the other side.

How changes propagate between Adyen and Slack

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Adyen Slack Sub-second propagation

DetectionAdyen notifies Stacksync of record changes through webhook events. Standard webhooks for payment events (AUTHORISATION, CAPTURE, REFUND, CHARGEBACK, and more) plus Management, Balance Platform, and report webhooks.

DeliveryEach detected change is written to Slack through its API, with automatic retries and rate-limit backoff.

Slack Adyen Sub-second propagation

DetectionSlack notifies Stacksync of record changes through webhook events. Events API webhooks, delivered over HTTP callbacks or Socket Mode.

DeliveryEach detected change is written to Adyen through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Adyen: Adyen does not publish fixed numeric rate limits; excessive requests return HTTP 429, and the Management API reports 'too many requests' in the error detail. Adyen recommends exponential backoff, and no rate-limit response headers are documented.
  • Slack: Per-method rate limit tiers; message posting is additionally limited per channel.
