Best Payment Gateways With 2000+ Integrations (Stripe, PayPal, Coastal Pay, and More Compared)

Let’s Define What “2000+ Integrations” Really Means for Your Payment Stack

Before comparing gateways, it is worth pinning down what an “integration” actually is. Vendors count integrations differently, and a 2,000+ figure can mean very different things in practice.

Three Types of Integrations

• Direct or native integrations: Pre-built, vendor-supported connections to specific platforms – e-commerce carts (Shopify, WooCommerce, BigCommerce), POS systems (Clover, Lightspeed, Toast), accounting tools (QuickBooks, Xero), CRMs (Salesforce, HubSpot), and vertical software (Mindbody, Kareo, Toast). These are the most reliable and lowest-maintenance because the vendor maintains the connection.
• Indirect integrations via iPaaS: Connections through automation platforms like Zapier (8,000+ apps), Make, Workato, and Integrately. These extend reach significantly but rely on the iPaaS platform as middleware. Useful for niche or long-tail tools where a direct integration does not exist.
• Custom API integrations: Built by your developers using the gateway’s API. Provides maximum flexibility but requires engineering time and ongoing maintenance.

How Coastal Pay Reaches 2,000+ Software Vendors

Coastal Pay’s 2,000+ integrations span POS systems, e-commerce platforms, ERPs, CRMs, invoicing tools, scheduling software, and vertical applications across retail, hospitality, healthcare, coaching, and B2B. Importantly, the directory covers both card-present (terminal/POS) and card-not-present (online/invoice) environments – something pure-play online gateways often do not offer in equal depth.

A useful working definition: an integration count is meaningful only if those tools can be connected in a supported way, with documentation and vendor support, not simply through a generic Zapier wrapper. The remainder of this guide uses this definition when comparing gateways.

Here’s Why Deep Integrations Matter More Than a Long Logo List

A high integration count is not the goal in itself. The goal is what those integrations enable – faster onboarding, fewer reconciliation errors, less custom engineering, and lower total cost of ownership for your payment stack.

Operational Benefits

• Less manual reconciliation: When payments flow directly into your accounting system and CRM, finance teams stop maintaining error-prone spreadsheets that match deposits to orders.
• Centralized reporting: A gateway that integrates with both your terminals and your e-commerce platform gives finance one source of truth for revenue, fees, and refunds across channels.
• Fewer duplicate data entry workflows: Customer records, invoices, and payment status can sync between systems automatically rather than requiring staff to copy data manually between tools.

Risk and Compliance Benefits

Tight integrations also reduce compliance and risk surface area. When payment data flows correctly into chargeback management tools, fraud screening systems, and audit logs through pre-built connectors, there are fewer brittle custom scripts to maintain and fewer points where data can leak or become inconsistent. For pharmacies, B2B merchants, and other verticals with regulatory requirements, this is meaningful.

Enterprise Project Risk

For enterprise IT teams, having pre-built, certified integrations dramatically lowers project risk. A native, vendor-supported integration with your ERP can ship in days. A custom integration to the same ERP can take months and require ongoing maintenance budget. The integration depth of your payment gateway is a direct input into your project timeline and total cost.

What Are the Top Payment Gateways That Can Plug Into 2,000+ Tools?

Five gateways realistically meet the 2,000+ integrations bar through some combination of native, iPaaS, and API-based connectivity. Here is how each is typically positioned:

• Stripe: Best for SaaS, marketplaces, and global online businesses with developer resources. Strong native integrations, excellent docs, and a massive iPaaS reach via Zapier and similar.
• PayPal (and Braintree): Best for consumer-facing brands that want a recognizable wallet button. Native plugins are everywhere; PayPal connects to thousands of tools through Zapier.
• Square: Best for U.S.-centric small and mid-sized merchants combining in-person POS, online checkout, and invoicing.
• Adyen: Best for large or international platforms and marketplaces needing unified global acquiring and complex enterprise features. Stronger when you have dedicated developer resources.
• Coastal Pay: Best for growth-focused merchants that need both card-present and card-not-present coverage with broad software compatibility, simple flat-rate pricing, dual pricing options, and instant approvals. Strong for multi-channel operators (retail, restaurant, hospitality, healthcare, B2B) who do not want to stitch together separate online and in-person providers.

Where Stripe and Adyen rely heavily on developer-led integrations and iPaaS for breadth, Coastal Pay combines a large native POS and software network with API and iPaaS options. The next section breaks down the differences in detail.

Here’s How Coastal Pay Stacks Up Against Stripe, PayPal, Square, and Adyen

Coastal Pay quick takeaway: 2,000+ direct software integrations, instant merchant approvals in approximately 2 minutes, flat 2.5% + $0.15 pricing, dual pricing to eliminate card fees, and bundled card-present, card-not-present, ACH, and alternative payment methods on a single platform. Built for multi-channel merchants who want one provider instead of stitching together specialists.

Where Coastal Pay Differentiates

Coastal Pay’s positioning is distinct in three ways. First, it bundles card-present terminals, e-commerce gateway, ACH, and alternative payment methods like Apple Pay, Google Pay, PayPal, Venmo, Klarna, Afterpay, and Coinbase on a single platform – meaning you do not need a separate POS provider for retail and a separate online gateway for your store. Second, instant approvals and fast onboarding contrast sharply with the longer underwriting and integration timelines that Adyen-class enterprise gateways often require. Third, practical enterprise features – multi-location hierarchies, role-based access, consolidated reporting across channels – are available without enterprise contract minimums.

How Should Developers and IT Teams Evaluate These Gateways for Real-World Use?

Integration count is one variable; the technical experience determines whether the integration actually ships and stays maintainable. Here is the evaluation checklist that matters most for engineering and IT teams.

API Fundamentals

• RESTful design: Consistent, predictable resource paths for charges, customers, refunds, tokens, subscriptions.
• Authentication model: API keys, OAuth, or HMAC; key rotation procedures; environment separation between live and sandbox.
• Versioning: Explicit version strings in API requests so upgrades do not silently break production.
• Idempotency: Idempotency keys on payment requests to prevent duplicate charges from retried network calls.
• Pagination: Cursor or offset-based pagination for transaction lists, with reasonable defaults.

Webhook Capabilities

Reliable event-driven flows depend on solid webhooks: comprehensive event coverage (payment success, failure, refund, chargeback, dispute, subscription events), signature verification using HMAC, configurable retry policies, and clear ordering guarantees. Coastal Pay’s gateway provides webhook events for the standard payment lifecycle and supports signature verification so your application can reject spoofed events.

Developer Experience

Look for sandbox environments that mirror production, sample code in major languages, Postman collections, and a clear path from API key generation to first test transaction. With Coastal Pay, developers can typically run a first sandbox charge within an hour of receiving credentials. Documentation is hosted at coastalpay.com/api-links.

Sample Charge Request

curl -X POST https://api.coastalpay.com/v1/charges \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: order_12345" \
  -d '{
    "amount": 5000,
    "currency": "USD",
    "source": "tok_visa",
    "description": "Order #12345"
  }'
      

Enterprise IT Requirements

• SSO/SAML: Single sign-on for the gateway dashboard via Okta, Azure AD, or similar identity providers
• Audit logging: Detailed action logs for compliance and forensic review
• IP allowlisting: Restrict API access to known IP ranges
• Rate limiting: Documented limits with clear error responses for retries
• Monitoring integrations: Webhook events that flow into Datadog, Splunk, or your internal monitoring stack

Documentation and Support

Documentation quality varies dramatically across gateways. Coastal Pay provides API docs, integration engineer support, and typical integration timelines for common stacks (Shopify and WooCommerce within hours via direct integration, custom API builds typically 1 to 4 weeks).

What’s the Best Way to Implement a 2000+ Integration Gateway Without Breaking Things?

A phased rollout dramatically reduces risk while still letting your team take advantage of the gateway’s full integration breadth.

1. Step 1 – Choose Pilot Systems

   Pick one core system (e.g., your e-commerce platform or ERP) and one secondary system (e.g., CRM or accounting) to integrate with Coastal Pay first. Avoid trying to migrate every connected tool simultaneously.

2. Step 2 – Map Data Fields and Flows

   Document how customers, orders, invoices, refunds, and settlement records currently flow through your stack. Map each field to Coastal Pay’s API equivalents – customer object, charge object, refund object, and so on. This step prevents most production surprises.

3. Step 3 – Test Comprehensively in Sandbox

   Run sandbox transactions covering test cards, AVS and CVV checks, refunds, partial refunds, chargebacks, and dual pricing scenarios if you plan to use them. Test both card-present and card-not-present flows if you operate across both channels.

4. Step 4 – Connect Long-Tail Tools via iPaaS

   Use Zapier, Make, or Workato to connect Coastal Pay to niche, vertical, or long-tail tools where a direct integration is not necessary. Keep mission-critical systems (POS, ERP, primary CRM) on native integrations for reliability.

5. Step 5 – Plan Cutover and Monitor

   Schedule the cutover during a low-traffic window with a defined freeze period. Prepare a rollback path back to your previous gateway in case of unforeseen issues. Train customer-facing and finance staff on the new dashboard. Monitor authorization rate, checkout error rate, and reconciliation time daily for the first two weeks post-launch.

Here’s How to Decide Which Gateway Makes the Most Sense for Your Team

The right choice depends on what your business actually does and how your stack is shaped. Here is a scenario-based summary.

Multi-Location Retail With E-Commerce

If you run physical locations alongside an online store, you need both card-present and card-not-present capabilities in one provider. Coastal Pay is typically the strongest fit because of its native POS reach, online gateway, multi-location hierarchies, and consolidated reporting in a single dashboard.

Software Vendors Needing Embedded Payments

If you are a SaaS or platform building payments into your own product, Stripe remains the developer-experience leader for embedded payments and marketplace flows. Coastal Pay is a strong alternative when flat-rate pricing, dual pricing, and direct merchant onboarding support matter more than developer ecosystem maturity.

B2B Merchants With Complex Pricing

For B2B operators dealing with corporate cards, ACH, and complex invoicing, Coastal Pay handles ACH and dual pricing in the same gateway as cards, which simplifies finance operations significantly compared to providers that require separate ACH agreements.

Global Enterprise Marketplaces

Adyen remains the enterprise standard for unified global acquiring across regions. If your business is U.S.-focused, Coastal Pay typically delivers comparable enterprise controls without enterprise-contract minimums.

Integration breadth alone is not enough. Pricing transparency, support quality, and omnichannel coverage matter just as much. Coastal Pay’s combination of 2,000+ integrations, instant approvals, flat-rate pricing, and bundled in-person plus online plus alternative payments makes it the strongest choice for organizations that want one provider for the entire payment stack without giving up integration flexibility.
