Embed · Extend · Connect
Pulse, wired into your platform.
Embed payments with a few API calls or a white-label checkout. Fiserv, NMI, TSYS, Plaid, Sovos, and 300+ Zapier connections — built and maintained by Pulse, not your team.

One integration layer
Pulse manages the connectors. You ship the product.
Building embedded payments means maintaining processor APIs, verification vendors, and compliance pipelines — unless you use Pulse. Pair the integration layer with the automation engine and merchant onboarding and the entire payment stack runs with minimal engineering overhead.
Native integrations
Processors and verification vendors, pre-wired.
Stripe & Maverick
Connect Stripe and Maverick for gateway-level transaction access, virtual terminal data, and real-time portfolio sync across every sub-merchant.
Slack
Push merchant status changes, fraud signals, and onboarding milestones to the right Slack channel the moment they happen — no polling required.
Documenso e-signatures
Trigger merchant agreements at the right onboarding step, track signing status in real time, and store every completed document alongside the merchant record.
Plaid & Smarty
Bank account verification via Plaid and live USPS-grade address validation via Smarty — both wired into the onboarding flow your platform exposes.
Sovos KYC & OFAC
Automated OFAC screening on every applicant and 1099 generation from settlement data — compliance obligations handled without manual spreadsheets.
Zapier (300+ apps)
Connect Pulse events to any tool in your stack through 300+ Zapier integrations — no custom webhook endpoints needed for the long tail.
ID.me identity
Trigger identity verification at the exact moment your onboarding flow requires it. Results flow back into the merchant record automatically.
Developer-first
Webhooks and a full REST API for your platform.
Webhooks
Subscribe to any Pulse event — merchant boarded, onboarding stage changed, fraud alert triggered, settlement posted. Sub-200 ms HTTP callbacks delivered to any endpoint your platform exposes.
REST API
Full CRUD access to merchants, onboarding applications, payment data, and more. Embed a white-label checkout, build a custom dashboard, or pipe data straight into your data warehouse.
POST /v1/webhooks
{ "event": "application.approved", "merchant_id": "482910", "dba": "Acme Coffee Co.", "risk_score": 87, "decision": "auto_approve", "ts": "2026-05-01T13:44:02Z" }
How it works
Embed, configure, automate, monitor.
- Step 1
Embed
Drop in the Pulse API or white-label checkout with a few lines of code. No processor contracts, no verification vendor negotiations.
- Step 2
Configure
Choose which events to surface in your platform, map merchant data fields, and wire Slack or Zapier for the notifications your team needs.
- Step 3
Automate
Layer the rules engine on top: when onboarding approves, trigger a Documenso agreement; when a fraud alert fires, push to Slack and pause the account.
- Step 4
Monitor
Health metrics, sync status, and event logs in one dashboard. Integration failures surface before your merchants notice anything.
Native, zero maintenance.
For supported services — Fiserv, NMI, TSYS, Stripe, Maverick, Plaid, Smarty, Sovos, Documenso, Slack, Zapier — setup is a credentials field and a toggle. Pulse owns the connectors, so when an upstream API changes, your engineers don't notice.
Custom, no ceiling.
Subscribe to events, hit the REST API, build white-label checkouts or pipe data into your warehouse. Webhooks deliver in sub-200 ms; the API covers merchants, onboarding, payments, and settlement data.
Outcomes
Ship payments faster. Maintain less infrastructure.
Ship payments without writing processor code
Pulse owns and maintains every processor and verification connector. Your engineers embed the API — Pulse handles Fiserv, NMI, TSYS, Plaid, and Sovos on the other side.
Trigger automation on real events
Pair the integration layer with the rules engine: when a merchant boards, fire a Documenso agreement; when a risk score spikes, push a Slack alert to your ops team.
Extend without a ceiling
Webhooks and the REST API mean your platform is never blocked by a missing native connector. Build white-label checkouts, custom portals, or BI pipelines on top.
One source of truth across your stack
Bidirectional sync and health monitoring keep your platform, Pulse, and every connected service reading from the same data — no reconciliation required.
Who it's for
Built for software platforms adding embedded payments.
- Vertical SaaS platforms adding embedded payments without managing processor relationships or certification timelines
- ISV engineering teams that want a single REST API to board merchants, pull transactions, and trigger payouts
- Product teams building white-label checkout or merchant-facing dashboards on top of Pulse data
- Operations teams using Slack who need merchant status, fraud alerts, and onboarding milestones pushed to channels automatically
- Compliance teams relying on Documenso for agreement execution and Sovos for OFAC screening and 1099 generation
- Data and analytics teams piping Pulse webhooks into their warehouse or BI stack via the REST API or Zapier
