Why teams connect Bill and Splunk
Feed the customers, invoices, and revenue records in Bill into Splunk in real time, so dashboards and reports run on current numbers instead of last night's export.
Bill holds the financial truth: who the customers are, what they were invoiced, what they paid, and what revenue landed. Splunk is where that data is turned into dashboards, reports, and metrics, but it only reflects the world as of its last load. When the connection between them is a scheduled extract or a hand-built pipeline, analysis runs a step behind the books, and the numbers on a chart rarely match the numbers in the finance system.
Stacksync keeps Invoices, Customers, Payments, Chart of Accounts in Bill in sync with Fired Alerts, KV Store Collections, Indexes, HTTP Event Collector in Splunk, field by field and in real time. A customer, invoice, or amount created or corrected in Bill shows up in Splunk within seconds, mapped to the right record. Where Splunk keeps its own accounts or users, the flow runs both ways, so finance attributes can enrich what Splunk already tracks.
There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning's reporting running on yesterday's figures.
Common use cases
- 01 Sync Customers and Invoices from BILL AR into a CRM or ERP so sales and finance see billing and payment status on the account.
- 02 Write Vendors created during ERP onboarding into BILL so new payees are ready to pay without manual re-entry.
- 03 Sync fired-alert history and saved-search definitions into Postgres so security and reliability teams query alert trends and detection coverage in SQL.
- 04 Ingest application, CRM, or database records into Splunk via the HTTP Event Collector so operational data lands alongside logs for correlation and dashboards.
Common sync patterns
Financial records land in Splunk for reporting
Invoices, payments, and revenue from Bill flow into Splunk as they change, so dashboards are built on live figures rather than a periodic extract.
One customer key across both
A customer or account in Bill is matched to the corresponding record in Splunk, so financial numbers join cleanly to whatever Splunk already reports on.
Revenue alongside the rest of the data
The amounts Bill records sit next to product, usage, or operational data in Splunk, so a single view combines what was billed with what actually happened.
What you can sync between Bill and Splunk
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.
| Bill objects | Splunk objects | How this pairing syncs | |
|---|---|---|---|
| Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. | KV Store Collections App-scoped, MongoDB-backed key-value collections at /servicesNS/{owner}/{app}/storage/collections/data/{collection} with full CRUD and batch endpoints. Genuinely bidirectional lookup/state store — read records out or write records in. | Bank Accounts is specific to Bill and KV Store Collections to Splunk — each maps to any object or custom field on the other side. | |
| Vendor Credits and Credit Memos AP and AR adjustments applied against bills and invoices; synced so balances stay accurate on both sides. | Indexes Index inventory and settings (retention, max size, event counts) via /services/data/indexes, with create and edit; loaded into a database for capacity, retention, and data-onboarding tracking. | Vendor Credits and Credit Memos is specific to Bill and Indexes to Splunk — each maps to any object or custom field on the other side. | |
| Bills Accounts-payable amounts owed to vendors, with bill line items; read and created via /v3/bills and pulled incrementally by filtering on createdTime/updatedTime. | HTTP Event Collector The write-in path: POST events and metrics to /services/collector (port 8088, or 443 on Splunk Cloud) authenticated with a per-input HEC token, so external records are indexed alongside logs for search and correlation. | Bills is specific to Bill and HTTP Event Collector to Splunk — each maps to any object or custom field on the other side. | |
| Vendors Payee master records; synced two-way with vendor/supplier tables in an ERP or accounting system so new payees don't have to be re-keyed. | Users and Roles Accounts at /services/authentication/users and role/capability definitions at /services/authorization/roles, with full CRUD; exported for access reviews or provisioned from an identity source of truth. | Vendors is specific to Bill and Users and Roles to Splunk — each maps to any object or custom field on the other side. | |
| Invoices Accounts-receivable invoices sent to customers; created and read via /v3/invoices to keep billing status aligned with the ERP or CRM. | Dashboards Simple XML dashboard and view definitions at /servicesNS/{owner}/{app}/data/ui/views; exported for backup and audit, or created and updated programmatically from version control. | Invoices is specific to Bill and Dashboards to Splunk — each maps to any object or custom field on the other side. | |
| Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. | Search Results SPL searches dispatched via POST /services/search/jobs return a search ID (SID); results are pulled from /services/search/jobs/{sid}/results once the job completes, or synchronously via oneshot/export mode. The primary read path for streaming indexed events out to a warehouse. | Customers is specific to Bill and Search Results to Splunk — each maps to any object or custom field on the other side. |
How changes propagate between Bill and Splunk
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.
Bill Splunk Sub-second propagation
DetectionBill notifies Stacksync of record changes through webhook events. Webhook event subscriptions (POST /v3/subscriptions) for bills, vendors, payments, invoices, and bank accounts, with polling on.
DeliveryEach detected change is written to Splunk through its API, with automatic retries and rate-limit backoff.
Splunk Bill Sub-second propagation
DetectionSplunk notifies Stacksync of record changes through webhook events. Time-range searches over indexed events (earliest/latest on _time or _indextime).
DeliveryEach detected change is written to Bill through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Bill: 20,000 requests per developer key per hour; login (POST /v3/login) capped at 200/hour; maximum 3 concurrent requests per developer key per organization. Spend & Expense API is a separate token at 60 calls/token/minute.
- Splunk: The management REST API throttles through search-concurrency quotas — max concurrent searches per user and role, plus per-CPU historical search limits in limits.conf — rather than a fixed per-request rate; exceeding quota queues or blocks jobs. HEC has per-token and per-instance throughput limits, and Splunk Cloud adds ingestion and API limits on top.

How the Bill and Splunk connectors work
Bill
- Integration surface
- REST/JSON (BILL v3 Connect API)
- Authentication
- Session-based: POST /v3/login with username, password, organizationId, and a developer key (devKey) returns a sessionId that is passed with the devKey as headers on every subsequent call; OAuth is available for partner/embedded apps
- Change detection
- Webhook event subscriptions (POST /v3/subscriptions) for bills, vendors, payments, invoices, and bank accounts, with polling on createdTime/updatedTime list filters as the fallback

Splunk
- Integration surface
- REST API (management API + HTTP Event Collector)
- Authentication
- HTTP Basic (username/password), or a session key from POST /services/auth/login sent as Authorization: Splunk <key>, or a bearer authentication token (Authorization: Bearer <token>). The HTTP Event Collector uses its own per-input token (Authorization: Splunk <hec-token>). Management API defaults to port 8089; HEC to port 8088 (443 on Splunk Cloud).
- Change detection
- Time-range searches over indexed events (earliest/latest on _time or _indextime); events are immutable once indexed, so incremental extraction advances a time cursor rather than a modified-date CDC feed. Config objects such as saved searches and KV Store are polled; alerts can push via a saved-search webhook action.

FAQ
Bill and Splunk integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bill and Splunk: authenticate both systems, choose the objects to sync (such as Bill's Bank Accounts and Vendor Credits and Credit Memos), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Bill: REST/JSON (BILL v3 Connect API). Authentication: Session-based: POST /v3/login with username, password, organizationId, and a developer key (devKey) returns a sessionId that is passed with the devKey as headers on every subsequent call; OAuth is available for partner/embedded apps. Splunk: REST API (management API + HTTP Event Collector). Authentication: HTTP Basic (username/password), or a session key from POST /services/auth/login sent as Authorization: Splunk <key>, or a bearer authentication token (Authorization: Bearer <token>). The HTTP Event Collector uses its own per-input token (Authorization: Splunk <hec-token>). Management API defaults to port 8089; HEC to port 8088 (443 on Splunk Cloud). Stacksync manages authentication, retries, and rate limits on both sides.
-
Bill: The v3 Connect API is REST/JSON; direct integrations authenticate with a session from POST /v3/login using a developer key, organization ID, username, and password, and the sessionId is scoped to that devKey. Splunk: Splunk exposes two API surfaces: the management REST API (default port 8089) for search jobs, saved searches, KV Store, indexes, users, and roles, and the HTTP Event Collector (default port 8088, port 443 on Splunk Cloud) for pushing events and metrics in — so the connector both reads from and writes into Splunk. Stacksync's field mapping accounts for these differences between Bill and Splunk without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Bill and Splunk records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Bill and Splunk connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Bill–Splunk integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Bill and Splunk. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
