You can integrate Tabby from PHP without tying the API client to Laravel or another framework: keep credentials, HTTP transport, serialization, and API resources in a reusable core, then add optional framework adapters for dependency injection, routing, and logging. Tabby describes a custom API path for merchants outside its supported platform integrations; its official guidance links to separate Quick Start, Checkout Flow, Technical Requirements, and Webhooks documentation. Confirm current request schemas, authentication headers, regional hosts, and error behavior in those official materials before coding.
Choose the integration route before designing the SDK
“Tabby integration” can mean a direct connection to Tabby or a Tabby payment flow mediated by a processor. These routes have different accounts, endpoints, checkout behavior, and responsibilities. The official Tabby merchant page describes a custom API solution for stores outside its supported platform integrations; use that documentation as the starting point for a direct PHP client: Tabby merchant guidance.

Amazon Payment Services (APS) also documents its own Tabby integration. That route is for merchants using APS, not a substitute specification for Tabby’s direct API. APS describes a browser form POST to its payment page, with parameters including command=PURCHASE, payment_option=TABBY, phone_number, and order_description. Its documented route supports KSA and UAE and lists SAR and AED. Do not transfer those parameters, market limits, or currencies to a direct Tabby client without confirmation from Tabby’s documentation. See APS’s Tabby integration documentation.

| Endpoint and authentication | Confirm current Tabby hosts, credentials, and headers in Tabby’s official API references. | Uses the APS payment-page flow and APS integration requirements; do not reuse it as direct Tabby API configuration. |
| Markets and currencies | Confirm coverage for the merchant account and market in Tabby’s official documentation. | APS documents KSA and UAE and SAR and AED for this route. |
| Checkout experience | Build around Tabby’s checkout-session flow and the current official return/redirect requirements. | APS documents a browser form POST to its payment page. |
| Lifecycle and webhooks | Implement the operations and webhook handling documented for the Tabby account. | Follow APS’s flow and the relevant provider documentation for status and event handling. |
| Client ownership | Your application or SDK owns the direct API client. | APS owns the processor-facing integration surface; your application still handles its own order workflow. |
Neither route is universally preferable based on the available documentation. Choose the one that matches the merchant’s account and operational setup.
#1 Best Overall
Separate a reusable client from checkout and order workflows
A PHP SDK should make HTTP communication reusable without pretending that every application has the same checkout, order, or fulfillment model. Tabby’s API catalog lists checkout session creation (POST /api/v2/checkout) and retrieval (GET /api/v2/checkout/{id}), and describes checkout as collecting customer data and authorizing payment. The catalog is secondary; use Tabby’s official references linked from its merchant guidance to verify the live contract before implementing these operations.
Keep the core framework-neutral
- Client configuration: accept credentials, an environment or base URL, and an HTTP transport through explicit configuration. Confirm the actual regional host and authentication requirements with Tabby rather than inferring them.
- Transport: isolate request sending behind an injectable HTTP client. This is an architectural choice that supports testing and use outside a framework, not a Tabby API requirement.
- Resources: expose focused interfaces such as checkout, payments, and webhooks. Keep endpoint-specific request/response handling out of controllers and application services.
- Serialization and errors: centralize JSON encoding/decoding and map API responses into predictable SDK results or exceptions. Confirm Tabby’s error semantics and response formats before promising particular behavior.
- Framework adapters: put service-container registration, facades, route helpers, and framework logging in optional packages or separate modules. A plain PHP application should not have to boot a framework to make an API request.
Keep application decisions in the application
The SDK can create or retrieve a checkout session and return the provider data needed by the application. The application should decide when an order is created or marked pending, which customer and basket data may be sent, how a customer returns from checkout, and when fulfillment is permitted. A browser redirect or return page is not, by itself, a reliable substitute for confirming payment status through the server-side workflow.
Rank #2
Keep internal order identifiers and idempotency decisions explicit in application logic. Do not assume that a provider checkout session and a shop order have identical lifecycles or that one API response settles every fulfillment question.

Checkout session creation and retrieval are the clearest operations in the available Tabby API catalog. Payment management is a separate concern: a secondary API profile describes retrieving, listing, updating, capturing, refunding, and closing authorized payments. Treat this as an indication of the areas to investigate, not a definitive current contract for endpoint names, state transitions, or partial-operation support. Consult Tabby’s official API references before encoding lifecycle guarantees.
| Capability | What to establish before implementing |
|---|---|
| Create or retrieve checkout | Current request and response schemas, required customer/order fields, redirect or return behavior, regional host, and authentication. |
| Retrieve or list payments | Supported identifiers and filters, pagination behavior, and which payment states can be returned. |
| Update, capture, refund, or close | Allowed state transitions, required parameters, whether operations can be partial, and the response/error semantics. |
| Order state changes | Your own rules for pending, paid, cancelled, refunded, and fulfillment states; map provider events without conflating them with internal order state. |
Represent lifecycle operations with clear methods and typed inputs rather than a generic “send arbitrary action” surface. This makes it easier to validate application intent and adapt if the provider’s supported transitions differ by merchant, market, or API version.
Make webhook handling a first-class integration boundary
Webhooks let the server receive payment lifecycle changes independently of the customer’s browser. An independent API profile describes HTTPS JSON POST events for actions such as authorize, capture, close, reject, expire, refund, and update, and says retries occur. Because this is not the authoritative current Tabby contract, verify event names, signature verification, retry policy, delivery behavior, and idempotency expectations in Tabby’s official webhook documentation linked from its merchant guidance.
Rank #4
- Expose an HTTPS endpoint in the application or an optional framework adapter; keep routing out of the core SDK.
- Verify the request using Tabby’s currently documented signing mechanism before processing it. Do not infer the signature algorithm or header from a third-party package.
- Record a durable event or delivery identifier when available, and make processing idempotent so retries do not repeat order or fulfillment effects.
- Apply a validated event to the application’s order state machine, then acknowledge according to Tabby’s documented response and retry requirements.
- Log enough context for reconciliation without recording secrets or unnecessary customer data.
Keep the Tabby secret and webhook secret on the server. A package README also warns against exposing them in front-end or mobile applications; treat that as sound backend practice and follow Tabby’s official current instructions for exact verification.
Decide whether an existing PHP package fits
Two package listings illustrate the early PHP ecosystem, but neither listing establishes production readiness. Packagist’s search preview for yasser-elgammal/tabby-php reported v1.0.0 published at 2026-10-03 08:43 UTC, PHP ^8.2, Guzzle ^7.0, and features including checkout, payment retrieval/listing/update, capture, refund, close, webhook management, and secret verification. The registry page could not be opened in the browsing pass, so these are preview details, not an independently reviewed package. The displayed release date is later than this article’s stated current date, 2026-10-11, but verify the registry listing directly before relying on that metadata.
The mustafataj/tabby-php listing describes a framework-agnostic core with Laravel integration, injectable HTTP clients, and checkout, payment, and webhook features; its README says Guzzle is used by default. Those are maintainer claims, not conclusions from a code review. Before adopting either project, inspect its current source, release history, dependency constraints, tests, license, security practices, and alignment with Tabby’s official API documentation.
Quick Recap
Build and verify in a controlled sequence
- Choose direct Tabby or APS. Confirm the merchant account, target markets, currency, and who owns the payment page or redirect flow.
- Read the relevant official docs. For direct integration, use Tabby’s custom API, Quick Start, Checkout Flow, Technical Requirements, and Webhooks materials. Confirm exact request contracts, credentials, hosts, and failure handling before coding.
- Define the core boundary. Specify configuration, transport, resource methods, DTOs, and error mapping independently of framework registration.
- Implement checkout first. Create and retrieve a session using the verified contract; keep application order creation, return handling, and fulfillment decisions outside the transport layer.
- Add lifecycle operations deliberately. Implement only operations the merchant needs, and verify legal state transitions and full-versus-partial capture or refund support.
- Add verified webhooks. Build signature checks and idempotent event processing to the official requirements, then exercise duplicate and out-of-order delivery cases in application-level tests.
- Test the transport boundary. Use a fake or mock HTTP transport for serialization, error mapping, and retry behavior; separately validate environment configuration and provider responses using the official testing procedure available to the merchant.
- Add framework adapters only when useful. Keep Laravel bindings or route helpers optional so the same core remains usable from plain PHP and other frameworks.
Common integration mistakes to avoid
- Copying APS’s form fields, endpoint, test values, or market assumptions into a direct Tabby client.
- Hard-coding a host or authentication header without checking Tabby’s current regional and merchant-specific instructions.
- Treating a successful checkout redirect as proof that an order is paid or ready to fulfill.
- Assuming capture, refund, close, or webhook behavior from an API catalog or package feature list without checking official semantics.
- Putting secrets in browser code, mobile binaries, logs, or client-side configuration.
- Building a framework facade into the only client entry point, making plain PHP usage dependent on framework bootstrapping.
- Processing webhook retries as new business events instead of making handlers idempotent.
