Why teams connect Ramp and Slack
Connect the financial records in Ramp with the work happening in Slack, so both stay current without exports or copy-paste.
Ramp 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 Cards, Users, Departments, Reimbursements in Ramp 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 Ramp 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 Read Reimbursements into a finance database for cross-entity expense reporting and reconciliation without manual CSV exports.
- 02 Two-way sync Transactions and their accounting codings with a Postgres warehouse so finance analyzes spend in SQL and pushes GL categories and memos back to Ramp.
- 03 Create or update records in a database when specific messages or reactions occur in a channel
- 04 Alert an operations channel when a data sync detects conflicts or validation failures
Common sync patterns
Where Slack collects payments or triggers charges: events land in Ramp
Payment and charge activity flows into Ramp 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 handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Ramp next to the customer they are helping, without logging into the finance system.
What you can sync between Ramp 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.
| Ramp objects | Slack objects | How this pairing syncs | |
|---|---|---|---|
| Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. | Users Workspace members with profile fields, synced against HR systems and identity providers. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. | User groups Handles like @support that map to teams in external systems. | Departments is specific to Ramp and User groups to Slack — each maps to any object or custom field on the other side. | |
| Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. | Files Uploads attached to messages, retrievable for archiving. | Reimbursements is specific to Ramp and Files to Slack — each maps to any object or custom field on the other side. | |
| Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. | Reactions Emoji responses that can drive workflows, such as approving a synced record. | Bills is specific to Ramp and Reactions to Slack — each maps to any object or custom field on the other side. | |
| Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. | Channels Conversations (public, private, DMs) that messages are read from and posted to. | Vendors is specific to Ramp and Channels to Slack — each maps to any object or custom field on the other side. | |
| Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. | Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods. | Funds (Spend Controls) is specific to Ramp and Messages to Slack — each maps to any object or custom field on the other side. |
How changes propagate between Ramp 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.
Ramp Slack Sub-second propagation
DetectionRamp notifies Stacksync of record changes through webhook events. Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events.
DeliveryEach detected change is written to Slack through its API, with automatic retries and rate-limit backoff.
Slack Ramp 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 Ramp through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Ramp: 200 requests per 10-second rolling window per source IP; exceeding it returns 429 Too Many Requests, and requests running over 60 seconds return 504. Results use keyset pagination (follow the page.next URL / start cursor); higher limits can be requested from support.
- Slack: Per-method rate limit tiers; message posting is additionally limited per channel.

How the Ramp and Slack connectors work
Ramp
- Integration surface
- REST API (Developer API v1)
- Authentication
- OAuth 2.0: exchange client_id/client_secret (HTTP Basic) at api.ramp.com/developer/v1/token for scoped bearer tokens; client_credentials grant for server-to-server and authorization_code for user-delegated access; scopes follow resource:permission (e.g. transactions:read, bills:write, accounting:write).
- Change detection
- Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events; otherwise poll incrementally (synced_after on transactions, from_created_at on bills) with keyset pagination, or read the audit-logs/events feed.

FAQ
Ramp and Slack integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Ramp and Slack: authenticate both systems, choose the objects to sync (such as Ramp's Users and Departments), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Ramp: Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events; otherwise poll incrementally (synced_after on transactions, from_created_at on bills) with keyset pagination, or read the audit-logs/events feed. On Slack: Events API webhooks, delivered over HTTP callbacks or Socket Mode. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Ramp side: Cards, Users, Departments, Reimbursements, plus custom fields where Ramp exposes them. On the Slack side: Channels, Messages, Threads, Users. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Ramp and Slack: Where Slack collects payments or triggers charges: events land in Ramp; Where Slack tracks people or companies: one identity; Where Slack handles customer conversations: billing context in view.
